How to Disinfect Your Phone, Device, Laptop, Keyboard

If there’s one thing we’ve learned in recent days, it’s that our health is closely tied to things we touch throughout the day. And what’s the one thing we touch more than a few times a day? Our phones! Or as the Journal of Hospital Infection refers to them, our portable Petri dishes.

It’s not certain how long viruses survive on surfaces, but the World Health Organization reports it may persist on surfaces for a few hours or up to several days. This may vary under different conditions such as the type of surface, temperature or humidity of the environment but just think now how often you touch your phone.

If there’s the slightest possibility that a surface has been infected, err on the side of caution and clean it with simple disinfectant to kill viruses and protect yourself and others. Clean your hands with soap and water or an alcohol-based hand sanitizer when soap and water are not available. Avoid touching your eyes, mouth, or nose. And for goodness’ sake, clean your phone!

What not to do

When it comes to disinfecting your phone and other electronic gear, you want to kill viruses and bacteria without doing harm or voiding your phone or device warranty. That means no dripping antibacterial wipes. Do not use a prohibited cleaner or do not spray anything directly on the device.


Follow these basic instructions for how to clean your phone, screens, keyboards and other electronic gadgets

  • Always unplug the phone or device before attempting to clean it.
  • Prepare a dry, soft cloth or open a packaged alcohol wipe designed for eyeglasses cleaning. Never use paper materials like tissues, napkins or paper towels. Paper contains wood pulp that can leave scratches and permanent marks.
  • Cleaning instructions vary from one manufacturer to another. If in doubt, consult the manufacturer’s website.
  • Allow the disinfectant to air dry on the surface for at least 10 minutes before you wipe down it with a soft, clean towel.
  • Clean frequently used phones, devices, and keyboards twice a day.


Apple has just updated its support page to say that you can clean your iPhone with 70% isopropyl alcohol poured or sprayed onto a clean, soft cloth, alcohol wipes or Clorox disinfectant wipes. Use only a soft, lint-free cloth. Avoid abrasive cloths, towels, paper towels, or similar items.

  • Avoid excessive wiping, which might cause damage.
  • Unplug all external power sources, devices, and cables.
  • Keep liquids away from the product, unless otherwise noted for specific products.
  • Don’t get moisture into any openings.
  • Don’t use aerosol sprays, bleaches, or abrasives.
  • Don’t spray cleaners directly onto the item.

Android, Pixel

For the Pixel 3a and other Android phones, Google recommends screen disinfecting wipes or eyeglasses cleaner on the screen and ordinary household soap or cleaning wipes, as needed. There are no restrictions on alcohol-based wipes.

Computers, tablets, keyboards, remote controls, mouses

  • Unplug and remove batteries, if any.
  • Spray 70% isopropyl alcohol on a cloth, never on the screen, keyboard or device.
  • If using an alcohol wipe, make sure it is not dripping wet. Wring it out a bit first as necessary, then proceed. You do not want to drip liquid into any openings, especially a keyboard.
  • Consider a wipeable cover for your laptop keyboard so you can disinfect it without suffering potential harm to the keyboard itself.


These EPA-approved disinfectants are good options for cleaning phones, devices, screens, remote controls, and keyboards. Check back often if out of stock, as we’re updating quickly as possible.


Due to the high demand, some of the products mentioned above are temporarily out of stock. I’ve just learned the SNiPER will be available within a couple of days, so keep checking. The alcohol wipes shown above are available at this writing. Also, look for rubbing alcohol, alcohol wipes, Clorox Wipes and Lysol Disinfectant Spray in Costco, Sam’s Club, local drugstores, supermarkets; department stores and dollar stores.

    Hi, Mary! Just before Thanksgiving 2019 you gave your readers a recipe from a chef for disinfecting countertops, etc., with Clorox and cool water. I have been using this and liking it. I wonder however, do I need to make the solution fresh each time I use it? The recipe you published was for a large amount and I think I cut it in half or less. Also, would this be safe to use in other parts of the house? Thank you for all your great tips!

    Thank you for this info! I wondered how SNiPER was comparing with other products. It is certainly my first preference for this kind of cleaning and protection. Good health to you, your family and staff, Mary!
