If you are determined to give toothpaste a go I would certainly experiment with a disposable piece of plastic and with different toothpastes; certain brands of smoker"s toothpastes for example are very aggressive and have quite large particles in them which could end up doing more harm than good. I would tend to keep clear of Brasso, Dura-Glit, etc, all of which have anti-oxidents in them to remove the tarnish off brass and I reckon could react with plastic (but there again, you could experiment). The abrasive which is considered to be the finest and produces the best polish is something called "Jeweller"s Rouge" which is high quality, 100% pure, very finely ground iron oxide. We used this in the labs as the final polishing agent when preparing opaque mineral specimens for reflected-light microscopy.

Another option (and a darned sight easier!) is to have the LCD cover replaced - I understand from posts on other threads that this costs just a few dollars.

You"ll find as many methods for cleaning a TV screen as there are people you ask. Then, just to add to the confusion, consult your TV"s owner manual and add another method or two.

TV screens are a magnet for dust. A simple weekly flick-over with a soft duster reduces the frequency you need to actually get stuck in and do a proper clean. That"s a good thing. And when you do need to do some polishing, the duster removes potentially dangerous particles that could be rubbed in and create scratches.

It"s very important that the cloth be washed regularly — something most people probably don"t do. Any trapped grit equals disaster when rubbed across your precious screen, and built-up gunk reduces their effectiveness, so just drop them in the washing machine after each use.

This is optional. If regular dusting does the job, great. But many people swear by these. They act like dust magnets and a gentle sweep over the screen can lift the dust completely. Pledge Grab It dry electrostatic cloths are popular and are available in most supermarkets.

But the fact is you simply cannot get a TV streak-free unless you use a bit of dampness. The odd Catch-22 is that for the first few months of owning a new TV only a light dusting is needed to keep it beautifully streak-free. It"s only after the first mystery household blobs and bits start to appear than the owner takes to their screen with a damp cloth — and that’s when the first streaks appear.

You can buy any of a billion or so HDTV/computer monitor cleaning solutions. If you do make sure there is no alcohol, acetone, acetate or ammonia in the solution. They will strip the screen of its magical chemical coating which helps reduce screen reflection.

Mostly because a dark screen makes it easier to see faint streaks or grime. Also, because it"s the sensible thing to do when introducing even tiny amounts of liquid to an electronic device.

Give it a gentle swish with a duster or a dry electrostatic cloth until all the dust is gone. Even small amounts of dust can act like sandpaper under a cloth, so be thorough. If there are no grubby bits or streaks on the screen after dusting then congratulations — the job is complete!

Apply a small amount of your cleaning solution directly to a micro-fibre cloth (never spray directly on to the screen) and wipe evenly across the screen starting from the top and working down. Catch any drips or streams if they start to flow downwards.

This step is only needed for faint traces of streaks which may remain. Use your second, dry micro-fibre cloth and very gently polish out the streaks. Do not apply any pressure to the screen as you polish. Your TV is comprised of several thin layers and it"s all too easy to permanently damage your set by pressing too hard against these delicate components.

Before you give into your impulses and wipe your screen with whatever you have at hand, let us stop you right there. Your display is way more delicate than you think, and if you want it to last a long time in optimal conditions, you’ll need to treat it with proper love and care.

The good news is that cleaning a computer screen is more simple than you think. You only need a soft cloth, a tiny bit of water, and the most delicate of touches.

As you would expect, not all screens are created equal, and some are more delicate than others. The safest way to figure out the proper care for your screen is to search for the make and model of your device, find out if it has an LCD, LED, or some other type of display, and search for the manufacturer’s instructions on how to care for it.

If you want to skip all that, there’s an easy way to avoid making a mistake that might not only result in irreparable damage to your screen but to your entire device. According to Joe Silverman, owner of New York Computer Help, a tech repair center in New York City, no matter how much money you spent on your computer or tablet, it probably has an LED or an LCD screen if you bought it within the last three years—and neither type benefits from window cleaner or highly concentrated alcohol.

That’s the uppermost layer of your screen, which is extremely sensitive to the acidity in alcohol and in compounds like ammonia or propylene glycol. These are often present in cleaning agents such as window cleaners and degreasers. Using these liquids will corrode the surface of your screen, resulting in scratches or even smudges you won’t be able to get rid of.

Things get even trickier when you’re dealing with touchscreens. On models like the Microsoft Surface, the display is the main input—as opposed to your mouse or trackpad on a regular laptop—so it’s ultra-sensitive, Silverman says. Using a strong liquid cleaner like a degreaser or a bleach-based disinfectant can obliterate the top layer on the screen. Combine that with high pressure, and you can kiss your fancy touchscreen computer goodbye.

Another downside to newer computers is their size and weight. If you decided to splurge on a new laptop, for example, you probably found one that has top-notch components, but also a slick, lightweight design. This format is only possible if everything in your laptop is smaller and thinner. In the case of your display, a thinner screen means a weaker barrier between your computer’s guts and the elements in the outside world.

Caring for your screen is simple—it only takes a little bit of water and a dust-free cloth, such as a microfiber wipe or the piece of fabric that came with your glasses.

First, turn off your computer and disconnect the charger. This might sound paranoid, but the benefit is twofold—you avoid any chance of triggering an electrical surge, and your screen will remain black, which will make it easier to see any dirt and grime.

Pour a couple drops of water on your cloth. Forget paper towels or the sleeve of that soft cotton t-shirt you love—microfiber is your best bet. Still, no matter how soft it is, a dry wipe could always leave micro-abrasions on your screen. The moisture will also help gather dust and particles while lifting grease from your display.

Use circular motions starting in the center of your screen and moving outward, so you don’t leave any streaks. If you can see any droplets or water traces on the glass while you clean, you’ve used way too much water. Gently dab the residual H2O with an absorbent cloth or tissue paper and start again.

If you’re dealing with next-level gunk, you can use isopropyl alcohol at 70 percent or lower, Silverman says. “That percentage is very important,” he explains. “We’d only use 90 percent or higher on dummy parts that don’t have sensors, like top cases and keyboards.” In these extreme cases, spray the alcohol on the cloth, never directly on the screen, and wipe it gently.

Just like solar damage, screen damage is cumulative. The more pressure you apply, the more abrasive a product you use, and the more often you use it, the greater the damage you’re inflicting on the protective layer of your display and the delicate sensors underneath it.

Maybe you can get away with using a high percentage of alcohol or even a window cleaner on your computer screen once or twice. But if you keep at it, eventually you’ll see the deleterious effects.

“You’ll see discoloration, lines (vertical and horizontal); sometimes it looks pretty and rainbow-like,” Silverman says. “Sometimes it’ll blink and sometimes you’ll see droplets of water or liquid in the back of the screen. There’s a lot of ways in which damage appears.”

The best way to avoid damaging your screen while cleaning it is to simply keep it from getting dirty in the first place. If you have a laptop, cover the keyboard with a thin microfiber cloth before closing it to prevent finger grease from transferring to the screen. If you have a touchscreen, wash your hands often before you use it, but make sure you let your hands dry completely before you start tapping—the soapy water or liquid hand cleanser from your fingers can easily end up on the screen and corrode it.

Your phone was designed to be carried, dropped, tapped, swiped, smashed against your face for long periods of time, and stowed in the deepest corners of your bag. In other words, its screen is way more resilient than your computer’s.

Silverman explains that most iPhones and Samsung phones, for example, have screens made out of one thick piece of glass. These, as opposed to computer screens, have all the LCD layers fused together, making them much more difficult to damage. Still, if you’re using alcohol, he recommends keeping the concentration at 70 percent or lower, using a soft cloth, and applying only low pressure to get rid of any accumulated gunk there.

Replacing the screen of your computer or smartphone can be expensive, and even if that’s not an issue for you, no one wants their devices to fail when they need them the most. So remember these tips well—we hope you never have to read this article again.

Starting from the top, wipe the screen in one direction until you have cleaned the entire screen. Apply light, but distributed pressure. Repeat if necessary. Let it air dry.

Can you read this line? Or is there a splash from a sneeze, or a greasy fingermark in the way? Perhaps another portion of your screen is dirty. The chances are that you don"t clean your screen often enough. In fact, we"re willing to bet that you"ve been putting it off for a while…

Cleaning a computer screen isn"t as difficult as you might think it is. Here"s what you need to know about how to clean your display, what to use, and cleaning it safely.

Splashes can obscure what you see on the screen. Smudges and greasy fingerprints accumulate over time to leave you with a dirty screen; dust gathers. The result is a viewing experience that is diminished by the presence of dirt.

Don"t have these things to hand? Don"t worry---you can also clean your computer screen with standard household products. Start off by making your own screen cleaner, using isopropyl (rubbing alcohol) or white vinegar, and distilled water.

Next, spray the screen cleaning fluid onto the lint-free cloth, wiping the display in straight lines. Don"t worry if the cloth dries out---simply apply another few squirts of cleaning fluid.

These devices attract more grease and dust than static LCD displays. As such, you"ll need to clean them in a slightly different way. Hybrid device touchscreen displays are cleaned in much the same way as standard tablets and smartphones.

The main aim here is to remove the grease, then clean the screen of other dirt and detritus. Our guide to safely cleaning a tablet or smartphone display will help you here.

Finally, if you use a hybrid or touchscreen laptop, you"ll need to be more aware of the problems with grease. Our dedicated tutorial, linked to above, will help you out here.

Once your greasy, dirty screen is cleaned up, you might feel ready to start using your computer again. But you shouldn"t stop there. It"s time to completely clean your computer. Using a notebook? Here"s how to clean your laptop and keyboard.

The television screen is what everyone sees first, but don’t forget these other key areas, not to mention the area around your unit. “It can also help to clean the furniture and carpets around the TV to prevent dust and hair from getting into it,” says Williams.

Start the remote control cleaning by removing the batteries. As with the TV screen recommendations, you’ll want to avoid spraying directly onto the surface, as this could cause the device to malfunction. Dampen a clean microfiber cloth and rub gently on the top and the underside of the remote control. For hard-to-reach gunk that’s jammed between the buttons, try a cotton swab dipped in a small amount of the cleaning solution. Make sure to let it dry thoroughly before replacing the batteries and using it again.

When figuring out how to clean a TV screen, selecting the safest cleaning solution is key, but it’s also important to know what cleaning products to avoid. Keep in mind that not only should you skip cleaning with certain products, you should also avoid spraying them in close proximity to the TV.

In terms of what to use, Samsung recommends “monitor cleaner only” (also called TV screen cleaner). Panasonic suggests “one part mild liquid dish soap diluted by 100 times the amount of water.” To make this cleaning solution, add a scant teaspoon of liquid dish soap to two cups of water, stirring well to dissolve.

Williams likes TV cleaning kits for their ease of use. “A TV kit will be your safest option for cleaning a TV,” he says. “These kits will come with everything you need to get your TV looking new, like screen-cleaning solvent and a fast-drying microfiber cloth.” You can find TV cleaning kits and cleaning products designed for flat-screen TVs at electronics stores or on Amazon.

Some people swear that only distilled water is useful as cleaning spray for their delicate electronics. Although Williams does not necessarily recommend using distilled water, if you know for a fact you have hard water in your area, you may want to try the distilled water route and see if you notice a difference. Hard water, which has high levels of calcium and magnesium, may leave a film or residue when it’s used for cleaning. Before you spray water to clean TV screens, try experimenting with tap water on a less-important screen, like an old cell phone, to assess the results.

If you can picture the hulking tube TVs (also known as CRTVs) of yore, you may also remember how delightfully easy they were to clean—a few spritzes of window cleaner and some wipes with paper towels and you were good to go—no special microfiber cloth required. But modern TVs with fancier technologies like LCD, OLED, and plasma call for gentler techniques. “Avoid using chemicals like alcohol, ammonia or acetones when cleaning your TV. These cleaners were safe to use for previous generations of TVs with glass panels, but as the hardware changes with time, the cleaning methods do too,” says Williams. Since some multi-purpose and glass cleaners are made with ammonia, skip the Windex.

Modern TVs are often smart TVs but the cleaning tips are the same as the ones for LCD, OLED and plasma TVs. The microfiber cloth is your TV screen’s best friend. “The majority of TVs you purchase today will be smart TVs, and the cleaning process is the same as TVs without smart capabilities,” Williams says.

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.

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.

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

Modern projectors are one of the best tools that any conference room can have. They also make for great additions to any living room or classroom looking to increase screen size. They are an affordable way to project images into large surfaces while still maintaining a clear, smooth, and sharp image. LCD screens have become an integral part of most projector’s optical assembly units since the 90s. In this article, we will show you how to properly clean and maintain the screen of an LCD projector.

LCD’s or Liquid Crystal Displays are the most common type of screen found on most electronic products. They are relatively affordable and very versatile, you can easily find LCD screens that are as small as a watch, or as big as a wall-mounted television set. They are used mostly in computer monitors, television displays, projectors, mobile phones, calculators, and even in military aircraft displays.

The screen works using the inherent properties of liquid crystals. The liquid crystals are usually held between two sets of transparent electrodes. When an electrical charge is passed between the electrodes, the molecules of the crystals can be manipulated predictably to form different images. Most LCD screens have internal control mechanisms that transform the signals coming from any given device into precise electrical inputs, these allow the screen to render any image we want.

If your screen gets dirty or damaged there is no need to panic. There are several solutions to keep an LCD screen well maintained and working properly. Let’s explore some of the main reasons the LCD projector screens get dirty or damaged.

There are multiple ways by which the LCD screen in your can stop functioning properly or decrease its picture quality. Maybe you can see a fractal of psychedelic colors when you project your image, or there is a visible line blocking the image that can’t be removed by simple cleaning. Let’s look at some of the most common reasons.

Depending on the issue you are having, it is important to understand the best ways to approach the handling of an LCD projector screen. On most projectors, the LCD screen is located within the optical unit of the device. One of the most common issues is dirt and stains stuck to the outer layer of the glass. This is by far the easiest problem to fix because there is no need to disassemble the projector to access its components. On our example project, we can see that there are stains and some dirt accumulating on the screen.

The black dots tell us there is some dirt stuck to the screen. The shadowy smear is probably a stain. For this simple cleaning job, it is important to know the best tools you’ll need to proceed.

One of the biggest mistakes people make when attempting to clean an LCD projector screen is rubbing their fingers on the screen to try and eliminate the issue, but this may cause further problems as hands tend to leave smears and stains on screens. If enough pressure is added you can actually damage the screen. To remove all the dust, dirt, and stains from the outer layer of the screen you will need:

These are common household items that you might already have in your possession! A lint-free cloth is very important because if the surface of the cloth isn’t smooth, you can easily scratch the screen.

Now comes the fun part! Clean the screen. Make sure you don’t apply too much pressure. Begin the cleaning using circular motions and remember to be gentle. The goal is to soak up the dirt or dust with a wet cloth. Most dust will get absorbed by the cloth and the dirt will loosen up. Any stain or smear should come right off when the alcohol is applied, this happens because pure alcohol is one of the best chemical solvents around. Once you have cleaned the screen, try passing a dry portion of the cloth to soak up all the remaining solution.

Now that you have cleaned the screen, you’re all set! Go ahead and test the projector and look out for any visual cues that might indicate that your cleaning wasn’t thorough enough.

Make sure you repeat this process as many times as possible till you see thing goes right. We recommend you keep the proper maintenance of your screen every time you use it. This is to allow the screen to remain as shiny and clear as possible. The more work you put into maintaining the LCD screen clean, the better the results will be. Save yourself the headache of seeing unwanted spots when you need to use the projector, and try to maintain it clean.

If you think the problem lies inside the projector’s optical unit, you can always disassemble the projector to see what is going on. We recommend you have your user manual with you in order to check what projector model you own. Do some internet research to check what type of LCD screen your projector houses, and if it can be replaced. The most common problem is the dust has entered through the cooling fan accumulating near the optical unit. To fix this you’ll need:

You can absolutely change the LCD screen of a projector. You can do this in a few simple steps. We recommend you contact the manufacturer to see how they can help you. Changing components inside a projector is a daunting task for most people, so you can save yourself the hassle by emailing or calling the manufacturer. If you want to do it yourself you can:

We hope you have learned a bit more about how projector LCD screens work. We also showed you some of the most common issues people run into with their projector LCD screens. How to keep the screen of your LCD projector clean is an easy task if you make sure you treat your unit with care and follow some simple instructions. Remember that most of the tools we used (e.g. water, lint-free cloth, isopropyl alcohol) are very common household items. So give it a go and enjoy your ‘newly-bought’ projector!

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.

Additionally, avoid paper towels, rags, old T-shirts, or any of the usual materials you use to wipe down surfaces in your home. Monitors are more delicate than they look, and these fabrics — even paper towels — are abrasive enough to scratch your screen, especially if you have used them for other jobs where they might have accumulated grit. A microfiber cloth — the kind you might use to clean your glasses or vinyl records — is the safest choice. Just make sure it’s free of any dirt or grime before swiping across your display.

Step 1: Turn off your monitor. It’s easier to see smudges and stuff on a black screen, so turning off your monitor makes it easier to see what you are doing. It’s also safer for you and your computer. Cleaning your monitor while it’s on and the pixels are all fired up could damage your screen or potentially give you an unpleasant electrical jolt. Please turn it off!

Step 2: Wipe your monitor with a microfiber cloth. If dust is the only thing on your screen, a quick wiping should be enough to clean it. Take the microfiber cloth and gently brush the screen in long motions. We cannot stress enough that you should be gentle: Pressing too hard on the screen could damage the pixels within.

There are gentle cleaning fluids designed for monitors, but distilled water works well, as mentioned earlier. It’s important you only use filtered or distilled water, however, since tap water contains minerals and other substances that can harm the screen or leave annoying streaks. For especially stubborn grime, add a bit of white vinegar to the water. Just be careful not to spill any on your laptop.

Step 4: It’s important that you never spray water or other cleaning fluids directly onto your monitor, or it might trickle down to the edge of the screen and seep into the monitor itself and damage the electronic components within.

Found this...dont know if it helps....this was for a computer lcd screen not sure if its the same for the lcd screen on the back of digital cameras. Maybe someone else could suggest an alternative.

1. First of all apply diluted isopropyl alcohol (50/50 with water) with a clean cotton cloth on the surface of the screen. This should make the surface clear of any dirt and then you can put Vaseline in the trough of scratch. Gently wipe the Vaseline left off the scratch. This should fill the scratch with Vaseline and you can again enjoy gaming or watching videos on your screen.

2. You can also do this trick to get you rid of the scratch if the scratch is particularly harsh. Start with cleaning the surface with diluted isopropyl alcohol (50/50 with water) as mentioned in previous way. Apply a bit of auto rubbing compound the scratched surface and polish the area. After that, use a piece of paper and make a very small hole (5mm) in its centre to spray clear lacquer on the surface. Leave the surface to dry after that.
