Cleaning your phone will help keep keep you free from all of these germs, according to health experts. Here are some simple tips for going about it.

The first step, whether you own an iPhone or a Galaxy, is to unplug and turn off your phone. 

Although directions vary slightly from there, the basics are the same.

If you use a protective case, take that off and wash it with warm soapy water. Let it dry thoroughly before snapping it back onto your phone.

In the meantime, take a lint-free cloth, such as an eyeglasses microfiber cleaning cloth, and dampen it with warm, soapy water. Then wipe down the exterior of your phone. Just a couple of drops of soap is all you need. Any dish soap will work, although Wirecutter recommends Seventh Generation Dish Soap.

Or you can use a technology-safe disinfecting wipe, but make sure it does not contain bleach. Isopropyl alcohol-based cleaning wipes are safe, according Apple and Samsung. Apple even specifically says Clorox Disinfecting Wipes are OK for wiping down the exterior parts of iPhones.

However, it is important to keep liquids and moisture away from any openings on your device. Do not wipe the inside of charging and headphone ports, and avoid using sprays or abrasives.

Clean your phone once a day for the best protection against germs, the Federal Communications Commission recommends. To further minimize your phones exposure to germs and moistures, the FCC also recommends taking the following steps:

• Keep your phone in your pocket, purse or car when you are away from home.
• Use a written shopping list instead of a list on your phone while shopping.
• Use a credit card instead of a mobile pay option on your phone.
• Use a hands-free device to make calls. That way you're not pressing your phone against your face.
