How to clean a touch screen / touch panel ?

1
Cleaning with a Microfiber Cloth


  1. 1
    Choose a microfiber cloth. This is ideal for cleaning a touchscreen. Some devices will have such a cloth included or perhaps you can borrow one you use on your sunglasses.
    • The cost of such cloth varies. For cloth recommended by companies for their products, the price can be considerably higher simply because of the recommendation. Look around for a good deal on such cloth or substitute with a cheaper but still effective microfiber cloth.

  2. 2
    Turn off the device before commencing to clean it. It is usually much easier to see where to clean when the device is switched off.

  3. 3
    Give the screen a once over by brushing it with the microfiber in small circles.This will remove the majority of simple imperfections.

  4. 4
    Only if truly needed, moisten a cotton cloth, even the corner of your cotton shirt, and repeat the small circular motions. It may actually be enough to just breathe over the screen and use that moisture to clean with.
    • Read the instructions accompanying the cloth you're using. Some of them need to be made slightly damp before use. If this is the case, skip this step and follow the cloth's instructions instead.
    • If dampening a cloth, it is best to use distilled water or a cleaner specifically designed for cleaning touch screens.

  5. 5
    Brush again with the microfiber cloth to finish off. Don't over-rub though! And if there is any dampness left, just leave it to air dry.
    • Do not put too much pressure on the screen when cleaning it.

  6. 6
    Wash the microfiber cloth. To wash the microfiber cloth, soak it in warm, soapy water. The warm water serves to open the fibers and release the grime that may have gathered. Scrub the cloth lightly while soaking it (not too hard or you will damage the cloth). After soaking, avoid squeezing out any excess water, let the cloth out to air dry. If you're in a hurry, you may want to blow dry it. Do not wash any screens with the cloth until dry (or lightly damp) to the touch.

Disinfection with Alcohol Gel

This method is good because the sanitizer kills all the germs. Please use this method sparingly!


  1. 1
    Get some alcohol gel. It is also known as hand sanitizer.

  2. 2
    Take a clean paper towel.

  3. 3
    Squeeze a little gel into the paper towel.

  4. 4
    Wipe down the screen.

  5. 5
    Use a clean microfiber cloth to remove smudges - but there shouldn't be any!

Tips

  • If you do not have a microfiber cloth and the cleaning can't wait, a cotton cloth or corner of a shirt will do in a pinch.
  • Make sure your device is off before you start cleaning the screen.
  • If possible get a case for your device to prevent bumping, scratching and prints from happening.
  • It is possible to purchase screen cleaning kits. Often these will include anti-static wipes. However, this may be an added expense that isn't worth the price; do some research first.
  • If you want to further protect you device you can buy a scratch guard, also known as a screen guard. It is a layer of film that protects the screen from the scratches that occur from everyday use.
  • Keep the touchscreen cleaning cloth in good, clean condition. Wash regularly to remove buildup of grime from the screen.
  • Isopropyl alcohol is best for cleaning screens, either HMI computers or mobile phones.Leaves no trace or marks. This can be bought from any chemist. 
  • Do not use paper towels or toilet paper or anything paper-based on your screen! It can get scratched up badly if you do! Also, don't use alcohol-based stuff, because it can damage your HMI computer/tablet.

Warnings

  • Never use the spit and rub cleaning method. It will only create grime on your screen that you will have to clean later.
  • Don't press too hard on the screen when cleaning or you might damage the display.
  • Never use anything containing ammonia to clean the touchscreen with unless the manufacturer has specifically stated a product. Ammonia can damage the screen.
  • Avoid using anything that is abrasive when cleaning a touchscreen.
  • Never use paper towels or tissue paper. They contain wood fibers that will scratch any plastic surface. You may not see the scratches the first time, but over time your screen will look like you used very fine steel wool to clean it which will leaving it looking dull and somewhat fuzzy.
  • Avoid spraying liquid or water direct on the screen; there is a risk of liquid leaking into the device and damaging it. Instead, always spray the liquid onto the microfiber, squeeze to remove any excess liquid, and then wipe.
