Our smart phones are filthy. Wiping off the screen improves the view. UV light is a good option to get rid of bacteria and viruses. Using chemicals or soaps on a smart phone can damage the phone.
The Soeland UV cellphone sanitizer is one option of a product designed to rid our devices of bacteria and viruses.
The UV radiation from the Soeland UV cellphone sanitizer is about 2000 μW / cm2, which can effectively fungi, viruses and so on. Under ultraviolet light, oxygen in the air decomposes, producing a small amount of ozone. Ozone is a strong oxidant and also effectively remove various pathogens.
If you want to fit larger tablets, remotes, keys (or different items altogether – baby bottles etc.) the Baby UV Sterilizer is another option.
Update: Apple posted an update on cleaning your iPhone that says it is ok to clean your iPhone
Using a 70 percent isopropyl alcohol wipe or Clorox Disinfecting Wipes, 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.
They specifically are saying isopropyl alcohol wipes are ok; they are not saying that spraying anything onto your phone to clean it is ok.
