Screens, especially touchscreens, collect a lot of dirt, grease and hair. This means that periodic cleaning is something we all have to and should do.

Now, plenty of people get away with wiping a smartphone screen against their t-shirt or pants or using a sleeve to clean a laptop display, but this is not the best way and can itself damage the display.

Do a quick search on the internet, and you"ll find that isopropyl alcohol is the weapon of choice in cleaning displays. This is true, but if used incorrectly, this chemical can also damage the display.

The big DON"T of using isopropyl alcohol is this -- don"t pour or even spray isopropyl alcohol on your display. If you put too much isopropyl alcohol on a screen, damage can occur in two ways:The isopropyl alcohol can seep between the layers of the display, completely ruining it and requiring the device to have a replacement screen fitted

Apple has, naturally, published detailed information on safely cleaning a whole range of products, from notebooks to tablets to smartphones. While this is aimed at Apple users, the information applies to other brands too.

If you have been wondering how to clean a monitor with isopropyl alcohol, then let me tell you that the answer is very simple. All you need is a lint-free cloth and a container filled with 99% pure isopropyl alcohol. To start, dip your cloth in the container of alcohol and wipe away grime from your screen without applying too much pressure. After cleaning, let the monitor dry completely before turning it on again.

Use a soft, lint-free cloth. Avoid paper towels or anything else that might contain fibers. If you"re concerned about your monitor"s finish, you should be especially careful when cleaning it with alcohol—so don"t use any kind of rag or cloth you"ve already used on something else. If you"re concerned about dust or other contaminants on the monitor itself, then go ahead and use a small piece of tape to pick up excess dust before cleaning the screen with isopropyl alcohol.

A damp cloth is best for cleaning the monitor"s screen. This will prevent you from scratching it with a dry cloth or paper towel, which could damage your screen and make it harder to see.

Use a lint-free cloth. You don"t want to leave behind any debris, so you want to avoid using paper towels or other cloths that have fibers that could stick to your screen.

Use only enough isopropyl alcohol to clean off the dust and dirt from your monitor. Overapplying the cleaning solution will cause it to evaporate too quickly and leave residue on your screen, as well as potentially damaging it if there"s too much moisture in the air.

If you"re using a circular motion with your cloth, wipe slowly and do not press down hard on any part of the surface of your display—you could cause permanent damage by scratching or marring it with too much pressure or speed! Instead, move lightly around each individual point until all traces of dust have been removed before moving onto another area (if needed).

The next step after this is drying off any excess liquid: if there is any left over after patting down with one dry portion of cloth material, use another clean section again but be careful not overdo it here so as not spill water into places where they should not go!

Let the alcohol dry completely before turning on the monitor. If you do not, it could damage your monitor and void your warranty. Allow at least five minutes for a regular monitor, and overnight for laptops—the liquid will evaporate faster in warmer weather than in colder.

If you are looking for a way to clean your monitor, then consider using isopropyl alcohol. Isopropyl alcohol is a common solvent used in the medical and pharmaceutical industries, as well as one of the most effective disinfectants around. You can find it at your local drug store or supermarket, usually labeled “rubbing alcohol” or “isopropyl rubbing alcohol”.

Isopropyl alcohol is also very safe to use on monitors because they do not contain any oil or other contaminants that can be removed by detergents such as soap. Another benefit of this cleaner is that it will remove fingerprints without leaving any residue behind (unlike commercial cleaners).

Cleaning your monitor with isopropyl alcohol is a simple way to keep it looking good. It’s also cheap and easy to do, so there’s no reason not to try it. The alcohol will remove dust and fingerprints from both LCD and CRT monitors, leaving them looking like new again!

These displays are not constructed to be touched. It"s very important to exercise care in the handling of a liquid crystal display. The tiny dots that make up the images on the screen are each a separate transistor/crystal. Pressure can "crack" pixels easily, and when the pixels are damaged, black spots fill those areas of your monitor.

Pressing and poking, whether with a dull object such as your finger, or a sharp object, such as a pen or knife, typically damages far more than one individual pixel.

Don"t attack a dusty monitor with a great deal of force, regardless of your cloth. Attacking a dusty monitor with anything transforms your wiper into a piece of fine gritted sandpaper. Use a Swiffer duster (the "feather duster" type with a handle... not the cloth), a microfiber or cotton cloth, or a can of compressed air to get the dust off before you clean with a liquid product.

Isopropyl alcohol at 100% would not be something you"d want to soak a piece of plastic in, but in a 50/50 combination with water (or even less) it will dissolve finger-print oil and many other marking agents and evaporate quite fast (thus while it may HARM plastic if left exposed it doesn"t get the chance) and it"s evaporation process forces the water around it to also evaporate quickly.

Display technology has come a long way in recent years. OLED and LCD screens are brighter, more colorful and responsive than ever before, but at some point, they all still succumb to dust, dirt and grime. What’s worse is that there are a plethora of cleaning products out there that claim they can make your screen sparkle again. But in our testing, we’ve found that the simplest route is actually the best. In this how-to, we’ll show you how to clean all the screens in your home, from TVs to smartphones.

Before we get to how to clean a screen, there are a few ways you don’t want to go about the process. The first, and most important, is that you don’t want to clean a display using substances like isopropyl alcohol or Windex. Alcohol- and ammonia-based cleaners can damage your screen’s anti-reflective coating. Using those substances repeatedly can lead to clouding and the coating becoming uneven.

Companies like Whoosh make cleaning agents that won’t damage your screen, but in my experience, you’re best off using distilled water. It’s more affordable than a dedicated cleaning agent and more versatile too since you can use it on a variety of surfaces. It also won’t leave behind any residue on your display, which is something I’ve seen products like Whoosh do occasionally. You can buy distilled water at a grocery store or make it yourself with some simple cookware.

Next, be mindful of what you use to wipe your screen. You want to avoid using paper towel, dish rags and anything else that may have an abrasive surface that will damage the coating on your screen. You can use the sleeve of an old but clean t-shirt. That said, you’ll get the best results using microfiber cloths. That’s because the fabric they’re made from is extremely soft and good at attracting dust. We suggest buying a pack of them so that you always have a clean one on hand. The last thing you want to do is use a dirty one and transfer any dirt and grime onto your display.

With all that out of the way, the actual process of cleaning a display is straightforward. If you’re only dealing with some dust, use a can of compressed air or an air blower to dislodge it. You can also turn to a dry microfiber cloth.

For anything more than that, dampen your microfiber cloth with a small amount of distilled water and then gently wipe the display. Once you’ve gone over the entire surface, turn over the cloth and use the dry side to remove any excess water. At this stage, avoid buffing the screen or using excessive pressure. You don’t want to work any particles into the surface of the screen.

That’s it. You should have a clean display now. Obviously, it will take longer to clean a bigger screen, but you can put to use the tips mentioned for all types of displays, including TVs, monitors and glass smartphone displays.

We"ve all had that moment: You"re sitting at your computer or laptop and the light hits your screen in a way to reveal an unsightly accumulation of streaks, fingerprints, and dust.

To help, we round up the most important things to know about cleaning your computer screen, whether it"s a Mac or PC. While it"s a simple process, there are a few important rules to keep in mind to make sure you"re doing it safely.

Computer screens are not all made the same, and thus can"t all be cleaned the same way. You"ll want to be careful no matter your screen type, but it"s helpful to know that displays come in two categories:Glass-coated screens: The screens on newer iMac displays and MacBooks have a glass overlay. Glass displays are a little less delicate than LCD or LED screens, and mild cleaning solutions, like rubbing alcohol, are generally safe to use on them.

LCD or LED screens:Windows computers and most touchscreens and matte displays are typically not coated in glass. Extra care should be taken with these screens so not to damage the pixels that make up the display.

Since there are so many computers, laptops, and monitors out there, each with their own set of variables and specificities, it"s smart to just simply err on the side of caution.

To clean a computer screen, you really just need two things: A microfiber cloth and filtered or distilled water. That"s to say you don"t need a special store-bought cleaning solution.

If you"d like some extra sanitation power, an equal parts mixture of water and vinegar is safe no matter your screen type. If you know that your display is glass-coated, you can also use an equal parts mixture of water and 70% rubbing alcohol.What you needTwo lint-free microfiber cloths

d3sign/Getty ImagesTurn the computer or laptop off.For safety reasons, begin by letting the device cool down completely. Dust, fingerprints, and smudges are also easier to spot on a black screen.

Wipe off dust with a dry cloth. Use a dry, lint-free microfiber cloth to gently wipe away any visible dust and dirt. If necessary, apply gentle pressure to remove surface-level smudges.

If any marks remain, wipe with a lightly moistened cloth.For glass-coated screens, you can use a mixture of equal parts water and vinegar or rubbing alcohol. For LED or LCD screens, use only water. Spray or lightly dab the solution directly onto the cloth and carefully wipe the screen from left to right.

Buff with a dry cloth and air-dry.If any streaks remain once the screen dries, gently buff them with the dry cloth. Before you turn your computer or laptop back on, allow the screen to dry completely.Note:Apple claims that you can use 70% isopropyl disinfecting wipes to clean any Apple product. Just remember not to get any liquid into the device"s ports or openings — to avoid this, you might want to wring out the wipe to remove any excess liquid before using it.

For the best advice for cleaning your screen, it"s a smart idea to check your owner"s manual, which provides the manufacturer"s specific recommendations. But since screens are especially susceptible to damage, there are a few general guidelines that apply, no matter the type of screen you own.

Turn off your computer before cleaning the screen. This is just safe practice where any amount of liquid is involved, but more specifically, any static on the screen could create a shock and damage the internal components.

Do not use abrasive cleaning solutions. This includes bleach (or any products containing bleach), hydrogen peroxide, or all-purpose spray cleaners. Using an abrasive cleaner can ruin the finish of your screen.

Use filtered or distilled water. Especially in areas with hard water, water containing minerals like calcium and magnesium can damage your screen or leave even more streaks.

Use only soft microfiber cloths.Even a fabric as soft as a cotton shirt has snags and uneven particles that can scratch a computer screen. For this reason, avoid T-shirts, towels, and paper towels. The exception is the Apple Pro Display XDR or iMac, which requires a special polishing cloth.

Never spray cleaning solution directly onto the screen. To avoid any risk of damage from excess moisture, mist the solution directly onto the microfiber cloth instead.

Do not wipe in circles. Wiping in circles can create uneven pressure and ultimately lead to screen damage. It"s also more likely to create streaking. Wipe in tight, Z-shaped motions, or in broad strokes from side to side.

Do not scrub.Apply gentle pressure only. Hard scrubbing can damage the internal components of the screen and could leave scratches or spots of discoloration or dead pixels that won"t go away.Melanie Weir

Don"t spray the screen because the mist can get in the sides and bottom/top of screen area and short out your monitor. Play it safe and spray the cloth. These things are expensive.

It is good to know that flannel is the best material to use to clean an LCD screen. I learned the hard way how important it is to use the right products to clean these screens. I was spraying on a general cleaner, with a paper towel and now my screen has a dull finish to it.

I am going to try the vinegar and water solution to see if this will help. I don"t have high hopes that my screen will look like new again, but now I know what not to do the next time I buy something that has an LCD screen.

I use a multipurpose biodegradable cleaner to clean my LCD screens. This is a diluted solution that I use to clean the glass in my home. I have never had any problem using this on my screens. I also use this on my iPad to get rid of all the fingerprints. I have found if I use this all the time it also seems to keep the fingerprints from building up as often.

I keep a small bottle of this mixed up all the time and always spray on the cloth before wiping the screen. I don"t mind the smell of vinegar so this doesn"t bother me. Because it is diluted in water it isn"t that strong anyway and quickly disappears.

You can use this cleaning solution for a lot of other uses in your home. It is safe for you and the environment and works just as good or better than cleaning products that have chemicals in them.

I have always wondered what was the best way to clean an LCD screen. After spending that much money on something I didn"t want to ruin it by using something I wasn"t supposed to. I have just taking a soft cloth and wiping away the dust when the screen is turned off. So far this has worked OK for me, but I like knowing I can use a liquid solution as long as I don"t directly spray on the screen.

First, you run the risk of having liquid run down between the diffusion layers on the LCD, or hitting the CCFL in there and shorting out your inverter.

It"s just as easy and safer to spray the cloth you wish to use rather than the screen itself. The screens are not sealed in anyway, so any drips can possibly cause damage if they get inside.

You don"t spray it on the screen because cleaners used to damage the seal on the bottom edge of the screen. I don"t believe is still happens as long as something reasonable is used. The warning is most likely still there simply to cover themselves if someone uses something that is much to harsh and allows it to drip down the screen.

I actually spray the liquid (i.e., eyeglass cleaner or the solution they make specifically for LCD screens) on the screen all the time, and haven"t noticed anything bad come of it. I think the fear is that the droplets from the spray makes permanent splotches on the screen. It"s there for only a brief second but maybe with the heat of the screen those splotches get burned in somehow? I"m not sure, but I"ve done it -- I wipe right away and do it when the screens turned off -- and I haven"t had any problems with it.

Q: I have a new LCD television, and I"m not sure how to clean it. With my old tube set, I just spritzed it with Windex, but the surface of my new TV isn"t glass.

A: "We recommend using LCD cleanser that can be purchased at any electronics store," says a customer service tech for Westinghouse, a manufacturer of popular LCD televisions. The cleaner can be found in both spray and wipe form. But what exactly goes into these LCD solutions?

Kai Hui of MG Chemicals, makers of one of many available LCD cleaners, explains, "The main ingredient in most wipes on the market is water. There needs to be a small percentage of isopropyl alcohol (IPA) to help get rid of the grease from busy fingers." Some LCD cleaning solutions may include up to 50 percent IPA, according to Hui, but any more than that could damage the screens.

Since I"d never suggest you spend more money than you have to, I"d start with a clean, soft cloth and regular ol" tap water. You can add just a capful of isopropyl alcohol to a glass of water if you need something to help loosen the greasy gunk on the screen, so it can wipe off more easily. Get the cloth damp and then apply to the screen instead of splashing the screen and trying to wipe up the liquid; and always -- always -- use a clean cloth, as tiny, hard particles trapped in the fibers can scratch the surface of your screen.

This is the ultimate guide to properly cleaning your flat-screen television without scratching it or causing any potential damage. Included in this guide will be the best cleaning techniques, as well as the ideal products to accomplish a brand-new appearance on your TV. This guide is full of must-have knowledge for absolutely anyone who wants their television to remain in pristine condition. As a bonus, this guide will also provide you with a detailed explanation and instructions on how to clean your TV remote control.

Nowadays, most televisions are manufactured with a soft plastic screen. As a result of this, TV screens are delicate and can be easilydamagedif cleaned with an improper solution or technique. Accidentally using the incorrect product on your television could result in permanent damage, such as fogging, discoloring, or scratching.

When cleaning a television screen, two different techniques work extremely well. The first technique focuses on spraying down a microfiber cloth and wiping the Televisions screen. Alternatively, you may spray a minimal amount of non-ammonia based cleaner onto the TVs screen and gently wipe it away. These two techniques are proven safe and will not result in any permanent damage to your TV’s screen, as long as you follow the necessary detailed instructions when performing the cleaning.

Certain products and items you never want to use on the screen of your TV since they will cause permanent damage. When gearing up to perform a television cleaning, you will want to avoid using regular tap water, wood-based wipes, isopropyl alcohol solution containing more than 50% alcohol, regular Windex, or any cleaners that are ammonia-based.

Many products that are not made specifically for cleaning electronics will harm your television. If regular tap water is used on the television screen, a visible residue will appear after the water has dried. Instead of utilizing tap water, you may choose to use distilled water combined with a microfiber cloth. The combination of distilled water with the microfiber cloth will cause any dust on the screen’s surface to cling to the damp cloth. Distilled water will also ensure that the anti-reflective coating on your TV’s screen does not become worn-out.

Though Windex is a common go-to product for cleaning many devices and appliances, using it on a television screen can cause permanent damage. The reason behind this is because Windex is an ammonia-based cleaner. Ammonia-based cleaners may cause a chemical reaction between the ammonia-based cleaner and the coating on the Televisions screen or cause clouding.

It is essential to avoid the use of any wood-based cleaning wipes on a TV screen. Wood-based cleaning wipes include paper towels, Kleenex tissues, along with any similar products. If wood-based wipes are used on the TV’s screen, there is a strong possibility that you would be left with a multitude of visible, permanent scratches on the screen. The reason why the scratching often occurs is how rough the fibers of these products are combined with how soft the screen on the TV is.

You have a few technique options to choose from when preparing to clean a TV screen. A 50% isopropyl alcohol-based spray, also known as a lens cleaner, is a simple option that many lean towards. When using an isopropyl alcohol spray, you will want to pay close attention to the level of alcohol in the spray and be sure to avoid any alcohol-based sprays that contain more than 50% alcohol, as this will over-dry the television screen.

When choosing to utilize the lens cleaner technique, you will also want to use a clean, soft microfiber cloth that does not shed any fibers. If the microfiber cloth does shed fibers, you will find that sometimes after you’ve already cleaned the TV, you have to clean it again. This is due to the small static electricity charge produced when wiping the TV’s screen, which will attract the fibers of a microfiber cloth.

Optionally, specific products are intended for use on electronics that are extremely gentle as they do not contain ammonia or alcohol. Windex makes a special electronics cleaner that works phenomenally and is highly recommended. Additionally, the product “Screen Mom” is specially formulated for televisions and is also a fantastic product.

If the television is not dirty but has acquired a collection of dust particles on the surface, compressed air may be the best option for this job. Using compressed air will inevitably eliminate the worry of causing potential damage to the screen since there is no possible way to damage the television with air. Compressed air is an easy, inexpensive, and fast way to clear any dust from the television, leaving the TV appearing brand-new.

The first option entails simply spraying the microfiber cloth down with the cleaning solution and using that to wipe the television screen. If this is the method that is chosen, you will want to be cautious of the amount of solution used. Ideally, the cloth should only be slightly damp after you’ve sprayed it down.

Accidentally applying too much solution onto the microfiber cloth and using the excessively wet cloth on the TV screen may result in permanent damage. When too much cleaning solution is applied to the TV screen, the cleaner tends to run down the screen into the bezel and any other nearby electronics.

Alternatively, you may mist the TVs screen directly with a small amount of the cleaning solution that you’ve chosen. Immediately after misting the screen, you will want to gently wipe away the mist with a microfiber cloth. If this is the option that you would like to utilize, be sure to be extremely careful to not spray too much cleaner onto the television – as this may drip onto the bezel along with any other nearby electronics very rapidly, resulting in permanent damage.

IMPORTANT: When wiping a television screen with any wipe, be sure to be gentle, and refrain from applying any excessive pressure. Applying too much pressure on the screen will result in distorted pixels.

Microfiber cloths are commonly located in the automotive aisle of any big box store, and the lens cleaner can often be found bundled in kits for eyeglasses. Alternatively, Amazon possesses an extensive assortment of microfiber wipes and appropriate cleaning solutions that can be shipped directly to your door.

This is because the TV remote is one of the most overlooked household objects when cleaning a home. TV remotes are commonly touched multiple times a day by nearly every person in a household. However, no one ever thinks to clean it. The rubber buttons trap and preserve all sorts of dirt, skin flakes, and hair.

When performing a deep clean on your TV remote, all you need when performing a deep clean is rubbing alcohol, also known as isopropyl alcohol, which comes in a solution or a spray cleaner. Typically, you’ll find this at your local grocery, pharmacy, or hardware store as a 50% water and 50% isopropyl alcohol mixture. Combine this with a clean toothbrush, q-tips, and a microfiber cloth.

Next, use the isopropyl alcohol mixture and spray the microfiber cloth down, but you’re going to want to be sure to not overspray, leaving the cloth dripping wet, as that may cause damage to your remote.

If there are any tighter crevices that the cloth couldn’t get to, use a q-tip sprayed with the isopropyl alcohol-water mixture and deep clean between the buttons. Once finished, put the batteries back inside of the TV remote. You can rest easy knowing that the dirtiest part of your home is now the cleanest.

Alcohol breaks up the human oils that creates smudges on the screen, your supposed to tab a little on a cloth and then wipe the oil away, then use a new clean spot and repeat, removing the oil onto the cloth as the alcohol evaporates fast.

Like the OP, I"ve always used a 50/50 mixture of isopropyl alcohol and distilled water. Just now, I seem to have damaged the screen of my (Late 2013) MacBook Pro Retina by cleaning it with this mixture and a microfibre cloth.

There is a coating on the screen that has rubbed off in a patch about a quarter inch wide and two inches long. It"s very noticeable, but luckily it"s on the bezel rather than the screen proper. I"ll probably live with it, as a repair would probably involve replacing the whole screen. ($$$$)

This was possibly the third or fourth time that I"ve used this mixture to clean this screen in the few months that I"ve owned this machine. It"s really annoying to find that the most expensive laptop I"ve ever bought has a screen that can be so easily damaged, using a cleaner that I"ve seen recommended lots of times on the web and which has worked well for me in the past.

Isopropyl Alcohol is commonly found as rubbing alcohol in the grocery store, usually in a 70% isopropyl alcohol 30% distilled water mix; there is no need to dilute it when it comes that way. Some stores may sell 100% isopropyl alcohol which should be diluted. Something about the 70/30 mix causes the alcohol to evaporate away in the most efficient manner, so it"s better to do that than a 50/50 mix.

Isopropyl alcohol should be used only when distilled water won"t do the job, because repeated applications can eventually damage more delicate finishes.

A variety of chemicals can be found throughout the electronic assembly and repair process, but no solvent appears more commonly than isopropyl alcohol. It is universally used for cleaning and as a main constituent of fluxes, but how much do you really know about isopropyl alcohol?

Isopropyl alcohol (CAS #67-63-0) is also referred to as IPA, isopropanol, 2-propanol, and even rubbing alcohol (more on that later). It dissolves a wide range of both polar and nonpolar soils, and is often used to dissolve and remove light oils, fingerprints, cutting fluids, flux residues, carbon deposits, and mold release. It is also readily miscible in water, which makes it an effective drying agent.

For electronic printed circuit board (PCB) assembly, you will find isopropyl alcohol being used either to clean flux residues from recently soldered circuit boards, or in PCB repair and rework. IPA is also used to remove solder paste or adhesive from SMT stencils. Maintenance cleaning with isopropyl alcohol is common for removing caked-on and burnt-on flux from SMT reflow ovens, wave soldering fingers, selective soldering nozzles, pallets, and anywhere else flux tends to collect in automated soldering processes.

Isopropyl alcohol is generally compatible with most materials used in electronics. As with any chemical product used, component compatibility must be determined on a non-critical area prior to use. The following are a list of common materials used in PCB assembly and their respective compatibility ratings:

When a solvent is not compatible with a substrate, it may cause crazing (micro-cracks) or soften the material. In the case of seals or gaskets, this incompatibility will cause parts to swell, shrink, or become brittle. This video shows an extreme example of acetone on polycarbonate, which causes it to fog, soften, and even scratch from contact with the plastic dropper.

Isopropyl alcohol is available in a large number of varieties and grades, which are generally differentiated by the amount of water in the solution and trace amounts of other chemicals or nonvolatile materials.

Isopropyl alcohol is hydrophilic, so it readily accepts water into an azeotropic solution. When you see on the label “70% isopropyl alcohol”, it refers to amount of alcohol in relation to the amount of dissolved water – i.e. 70% alcohol to 30% water. Water can be removed to form purer grades of isopropyl alcohol, resulting in what is called “anhydrous” isopropyl alcohol.

Whether an IPA has 0.2% or 50% water has little effect on the look and smell of the material, but greatly impacts surface tension (its ability to wet) and the dry time. The more water isopropyl alcohol contains, the greater the surface tension. This causes the solvent to bead up more as it dries rather than wet or sheet, which can lead to spotting. “Water spots” are particularly problematic when cleaning mirrors, lenses, and other optics.

The dry time is greatly increased as the percentage of water in the alcohol solution is increased. This can be an advantage or disadvantage depending on the application. For example, isopropyl alcohol is often used as a flux remover to remove flux residues from around solder joints. Technicians tend to prefer a fast dry time so that they can clean the electronics and bring them back into service as quickly as possible. When breaking down and removing thick, gummy, or baked-on materials, more dwell or soak time is required. Slowing down the dry time often improves the cleaning effectiveness. That is one of the reasons 70% pure isopropyl alcohol is commonly used for degreasing and SMT stencil cleaning. In the case of electrical contact cleaning, the faster evaporation time helps ensure that the flammable solvent is gone before energizing the equipment.

The general term “rubbing alcohol” is often used for isopropyl alcohol, but users looking to buy a specific grade of alcohol should avoid products labeled that way. Rubbing alcohol does not refer to a specific grade, and may even be a different type of alcohol, like ethanol (also called ethyl alcohol, CAS #67-17-5). Consumer rubbing alcohol can also contain other ingredients like denaturant, fragrances, and colorants that are potential contaminants. ASTM D770 (currently on revision 11(2019)) is the standard specification for isopropyl alcohol published by ASTM International.

As mentioned above, isopropyl alcohol is also available in different grades, or percentages of solvent to water, to fit a variety of specific applications. When deciding on the best isopropyl product for a particular manufacturing or repair process, first decide on the grade of solvent, then the packaging.

Bulk containers- Isopropyl alcohol is packaged in 1 gallon bottles, 5-gallon containers, 54-gallon drums, and even totes for automated dispensing. In most cases, a spigot can be attached to the 1 and 5 gallon containers for convenient dispensing in benchtop or workstation use. When transferring to another container, make sure the smaller bottle is properly marked with the chemical name and warning information.

Small bottles / spray bottles- To avoid the risk and hassle of pouring and labelling smaller containers, isopropyl alcohol is also available in smaller plastic containers like pints and quarts. Some have a trigger spray attachment for convenient cleaning.

Pump dispensers / dauber bottles- Empty bottles are available to make dispensing even more convenient. A wipe or swab can be saturated in the opening, which is filled with a valve when the user pushes down. This keeps the isopropyl alcohol sealed, which avoids cross contamination when a wipe is resaturated after use, causing it to draw in moisture from the ambient air. These bottles can come with a variety of features including ESD-safe materials and a selection of labels for standard chemicals like IPA.

Presaturated wipes- For the ideal mix of form and function, wipes are available, and are already saturated with isopropyl alcohol. They can come in pop-up tubs where the wipes are pulled up from the top, plastic boxes or pouches that reduce linting caused by wipe perforations, and even individually wrapped packages. The individually wrapped wipes are perfect for field maintenance because they fit neatly in a tool box.

Although isopropyl alcohol is generally considered safe if handled properly, it is a flammable solvent, so precautions need to be taken to prevent a dangerous situation from developing.

Storage- because isopropyl alcohol is very flammable, it needs to be stored in a closed container in a cool, well-ventilated area away from ignition sources like heat, sparks and flames. It has an NFPA rating of 3, so it should be stored in a cabinet or room designed for that type of hazardous material. If solvent is transferred to another container, make sure it is marked with the chemical name and required warning information.

Personal protection equipment- isopropyl alcohol has a tendency to defatten the skin, which means it draws out the protective oils from the skin and can lead to dermatitis if improperly handled. Gloves made of nitrile or other solvent-resistant materials should be worn. Glasses or even a face shield should be worn if the user is spraying an IPA product, or if splashing could occur. Respirators can be used if ventilation is not adequate enough to avoid breathing in a high concentration of vapors.

Disposal- isopropyl alcohol needs to be disposed of as a hazardous liquid according to state and local requirements. It certainly cannot be flushed down the drain, and additional disposal requirements may need to be followed depending on the soils dissolved in the waste material.

Safety Data Sheets (SDS)- The central resource for all safety requirements is the SDS, which should be readily available wherever isopropyl alcohol is used.

Is it any wonder isopropyl alcohol can be found in all corners of electronic PCB assembly, rework and repair operations? It is effective, reasonably priced, and safe if handled properly. To buy isopropyl alcohol in the grade and packaging that is best for your application, go to www.techspray.com.
