How to clean a touchscreen

Do you always wash your hands before using your laptop, tablet, or smartphone? Neither do I. And the result isn’t pretty. A chemist could probably take samples from my iPad’s capacitive touch screen right now and tell you what I had for breakfast.

Touch screens need to be cleaned often. They get dirty quicker than non-touch screens, and the dirt interferes with both the visual experience and touch sensitivity.

You don’t have to buy anything expensive or special. Touch screens may be high-tech, but the job of cleaning them requires only simple tools and elbow grease.

You will need a microfiber cloth. You may already have one. Perhaps it came with some devices. Or your eyeglasses. If not, you can buy them for a few dollars at computer stores, camera stores, and various places online.

Display as white an image on your screen as possible. For instance, you can create a new word processing document and not type anything in it. The white background will make it easier to see the dirt.

Now wipe the screen, applying only slight pressure. Try straight wipes horizontally across the screen. If that doesn’t work, try wiping vertically or using circular motions.

If the screen is still dirty, you’ll need to prepare my secret screen-cleaning potion. Fill a spray bottle to approximately the halfway point with distilled water. Then fill it the rest of the way with white vinegar. Close the bottle and shake it.

Shut down your computer or device. You don’t want electricity going through it right now.

Spray a bit of the potion onto a microfiber cloth, preferably a clean one. Do not spray directly at the screen. Then wipe as described above.

When you’re done, wipe it again with a clean, dry microfiber cloth—or at least with a clean, dry corner of the cloth you’ve been using. Don’t turn on the device until the screen is dry.

Eventually, you’ll have to clean the clothes. Microfiber Wholesale offers detailed instructions.
