How to Clean a Phone or Tablet
Phones and tablets have an oleophobic (fingerprint-resistant) coating that could come off, so manufacturers generally recommend wiping them down with distilled water and a barely textured microfiber cloth and then using cotton swabs to clean around crevices, like the edges of the screen and buttons.
But a global pandemic is no time to heed manufacturer warnings. In March, Apple, in fact, revised its “How to Clean Your Apple Products” guidelines to endorse using “70 percent isopropyl alcohol wipe or Clorox Disinfecting Wipes.” According to Cupertino, “you may gently wipe the hard, nonporous surfaces of your Apple product, such as the display, keyboard, or other exterior surfaces. Don’t use bleach. Avoid getting moisture in any opening, and don’t submerge your Apple product in any cleaning agents. Don’t use on fabric or leather surfaces.”
If you can’t find any Clorox Disinfecting Wipes, get some 99 percent isopropyl alcohol, distilled water, a spray bottle, and a disposable microfiber cloth. Mix a solution that is 70 percent alcohol and 30 percent water and put it in the spray bottle. Then remove any case from your phone or tablet, spritz the cloth with the solution, and thoroughly wipe down your phone. Do not reuse the cloth.
If you’re concerned about your screen, put on a tempered-glass screen protector so you don’t damage the actual screen. Though it’s likely to be treated with a coating as well, it’s at least easily replaceable and won’t cause damage to the device itself.
Before you put the case back on, go over it with the solution and a cloth and let it dry completely. Then be sure to wash your hands, or all your cleaning will have been for nothing.
If you’re just concerned about grime and not germs, you can use wipes like Care Touch Lens Cleaning Wipes.
