isopropyl alcohol lcd screen supplier
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
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:
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.
Most are aware of IPA 99% highly effective utilization for medical use and as a laboratory solvent, but Isopropyl Alcohol plays an important role in the everyday maintenance of electronics for businesses, manufacturers, and consumers.
Isopropyl Alcohol 99% is the best substance to use for this purpose. Isopropyl Rubbing Alcohol 91% may also be effective, but it is best to use the purest IPA available.
A cloth, cotton swab, or cotton swab can be applied with Isopropyl Alcohol 99% to the electronic parts that need to be cleaned, but be sure not to leave any fibers on the device components.
LCD Displays are interfaces of human and machine. They expose to various environments, especially now that COVID-19 spreading around the world. So it"s impossible to keep a screen clean all the time. When you are going to clean an LCD display,do you have the right steps in mind?Maybe what you"ve been doing is not right!
LCD screens could have different top layers. For example, there are glass, plastic, coating, or protective bezels. Each one of them is different. Therefore, each type of screen should not be cleaned in only one way. In fact, the most appropriate way is written in product manual. Take Topway HMT070ETD-1D, a 7 inch Smart TFT LCD Display with capacitive touch screen, as an example. Cleaning precautions are as follow: Only clean LCD with a soft dry cloth. Isopropyl Alcohol or Ethyl Alcohol. Other solutions(e. g. water) may damage the LCD.
LCD screens are fragile. Before cleaning an LCD display, you should turn it off completely, disconnect it from power supply, and let it cool down for a few minutes. This will eliminate danger of electrocution and make it easier to see dust on screen.
Don’t press down hard while cleaning, because that action may damage top layers or coating. Spray a little cleaning solution, such as isopropyl alcohol diluted with either pure or distilled water, onto a microfiber cloth and gently wipe the display in either an up and down or side to side motion. Too much pressure can compromise limited durability of even the most rugged LCD screens.
It is dangerous that an LCD display directly contacts with any liquids (especially when they’re still plugged in). A safer and smarter approach is to first wipe the screen with a dry cloth, then spray a small amount of cleaning solution onto another cloth and wipe gently. After that, wipe with another clean, dry cloth to remove the residual liquid.
Never use ammonia or rubbing alcohol based cleaners on LCD screens. They will damage the extremely delicate coating on top of screens, and negatively alter viewing experience, especially in strong sunlight.
Dust in gaps where bezels and top layers meet can cause internal damage to LCD displays. Regularly using a vacuum with a soft-bristled brush (to prevent scratching) can be helpful.
Now you know how to clean an LCD screen safely and correctly, if you find it helpful, please share this article with your friends. If there are more questions about LCD displays, please feel free to leave us a message.
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.
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.
Remember when your LCD or OLED display had that brand-new, fresh-out-of-the-box shine, feel and look? You are in the right place if your display is now due for deep cleaning.
A microfiber cloth and distilled water is recommended for cleaning the display glass. Use Qtips and Isopropyl alcohol for cleaning the printed circuit board.
Only use a microfiber cloth and don"t use chemicals to clean a resistive touchscreen.Disconnect the display from the power supply and remove any screen protectors or liners.
Isopropyl alcohol (IPA) is widely used to clean printed circuit boards (PCBs). Use a Q-tip or soft small bristle brush for scrubbing a PCB, and never use a paintbrush.Gently rub a Q-tip in Isopropyl alcohol.
Cleaning soldering residue on LCD with Isopropyl alcohol and a Q-Tip.Cleaning residue around soldering elements is not necessary if Newhaven Display performed the soldering.
Cleaning your electronic display is a simple task. However, it is essential to consider these steps to handle and clean it properly. You should now have a better understanding of what cleaning products are safe to use, how to clean the display screen glass, how to clean touchscreens and how to clean soldering residue.
If any marks remain, moisten the cloth with LCD cleaner, and then gently stroke the cloth across the display in one direction, moving from the top of the display to the bottom.
Notice: Do not use any of the following chemicals or any solutions that contain them: acetone, ethyl alcohol, toluene, ethyl acid, ammonia, or methyl chloride. If you have a different chemical or solution and are not sure whether it is suitable, do not use it. Using any of the chemicals in the previous list may cause permanent damage to the LCD screen. Some commercial window cleaners contain ammonia and are, therefore, unacceptable.
Note: Many cleaning solutions are sold specifically as LCD cleaners. You can use these to clean LCD screens on Dell laptops. Alternately, you may use a 50/50 isopropyl alcohol and water mixture. Microfiber cloths such as those used to clean eyeglasses are excellent for use with LCDs.

There are a few different types of screens, and your cleaning options vary between the surfaces. It’s critical to know how to clean your specific screen because, if you do it wrong, the active ingredients in the cleaning agents could affect the display of sensitive crystals or cause permanent damage in the form of streaks and scratches.
It doesn"t hurt to wipe down the surface of your keys and your mouse at the same time you"re cleaning your screen, since many germs are housed on those surfaces. Using a dry microfiber cloth is always safest when it comes to removing dust.
Are there different considerations for cleaning a Mac screen versus a PC screen? In short, yes. We know that there are hundreds of different computer and monitor models to consider, but in general, screens are either backlit LED made with LCD (liquid-crystal display) pixels, or a non-LCD glass-coated surface. And just to note, some of the newer matte glass screens are nano-texture glass, which require a special polishing cloth from the manufacturer and should be cleaned with nothing else.
LCD screens are more susceptible to damage by cleaning agents, but because they’re commonly used on PC laptops and standalone computer monitors, there are lots of easy-to-use products available to clean them. It’s not that they’re hard to clean, but you’ll have to be careful and diligent so you don’t damage the surface or any of the LED elements. Any cleaners that include ammonia will leave a film. Soap and water can cause damage. It’s always safest and most effective to use an LCD cleaner free of alcohol, ammonia and acetone to clean an LCD screen, but if you need a DIY fix, you’ll be successful if you use a microfiber cloth that’s sprayed lightly with a mix of vinegar and distilled water.
Most Mac computer screens are glass-coated and can be cleaned and resolved streak-free more easily than LCD products using glass cleaners, like Windex, or a cloth lightly sprayed with rubbing alcohol. Nano-texture glass screens on products like the Apple Pro Display XDR or iMac require use of the special polishing cloth sold by Apple.
For fingerprints and smudges, spray 70% isopropyl alcohol onto a cloth, or use a pre-moistened alcohol wipe or a Clorox Disinfecting Wipe, to clean non-porous surfaces like the screen; do not use bleach.
To clean spots and streaks on the surface of the screen, mist an LCD cleaning spray onto a dust-free side of your microfiber cloth; an easy DIY solution is 1:1 parts of white vinegar and distilled water.
Regularly cleaning your LCD monitor keeps it free of dust, smudges, and germs. Wiping with a dry microfiber cloth is the safest cleaning option and is surprisingly effective at removing germs. You may need to use a dampened microfiber cloth to get rid of stubborn smudges and stuck-on debris, though. If you"re worried about germs, consider using a vinegar and water solution or a Lysol wipe on the screen. Be sure to check the device’s user manual first to make sure it’s okay to use liquids!

Windows 10 laptops are built to be mobile, which means that a dirty screen is inevitable. A dirty laptop screen can become a source of frustration with those fingerprints, mystery spots, and smears a distraction. Unfortunately, there isn’t a magical solution to this problem and from time to time, the laptop screen will need to be cleaned. However, laptop screens are easily damaged, so it is important to follow manufacturer guidelines when cleaning them.
Cleaning a laptop screen is a delicate procedure, so a gentle touch is needed when wiping down the screen. All laptop manufacturers recommend using a soft cloth when cleaning the screen, most opt for a microfiber cloth to avoid damage. Before starting the cleaning process, it is best to turn off the laptop, disconnect the power cord, remove the batteries, and disconnect any external devices. As a safety precaution, disposable gloves should also be worn during the cleaning process.
According to HP, one of the keys to safely cleaning your laptop screen is choosing the right cloth or material. Common household materials, such as rags and paper towels, can cause damage to the screen. The best material to use when cleaning the laptop screen is a microfiber cloth. For non-LCD screens, a few drops of rubbing alcohol can be used on the microfiber cloth, but do not use alcohol when cleaning an LCD screen. It is important to check with the manufacturer to discover what cleaning products are safe to use on a specific laptop screen. Under no circumstance should any cleaning product be directly applied to the screen. Instead, the rubbing alcohol or other cleaning product should be dabbed onto the microfiber cloth first.
When the microfiber cloth and choice of cleaner have been gathered, there are proper techniques that should be used to clean the laptop screen. After dabbing the microfiber cloth with rubbing alcohol or another cleaning solution, start in the center of the laptop screen and gently wipe in a circular motion. Gently continue wiping in a circular motion until the surface is free from dust and dirt. Keep in mind not to directly apply the cleaning solution to the laptop screen and avoid using the moist section of the cloth on the corners of the screen. If a tough stain is encountered, it is better to find a stronger cleaning solution than to rub the screen harder.
Dell also says that cleaning liquids should never be directly poured or sprayed on the laptop display screen and that a microfiber cloth is used. Lightly moisten the microfiber cloth with a cleaning solution, Dell recommends a mixture of 70-percent isopropyl alcohol and 30-percent water. Gently wipe the cloth in one direction starting from the top of the screen and work to the bottom. After the screen is cleaned, make sure the surface is completely air-dried.
Samsung recommends using a microfiber cloth as well. Using a dry microfiber cloth, gently wipe down the laptop screen, but don’t press too hard. Using only water or a mixture of 50-percent distilled water and 50-percent white vinegar, gently wipe the screen, remembering not to press too hard. Again, allow the screen to dry before firing up the laptop for use. Alternatively, Samsung also suggests compressed air as another way to remove dust from a laptop screen.
