Remember when Apple used to tell us that it was not safe to clean your iPhone's display? The company used to say it was unsafe to use disinfecting wipes or sprays because it might damage the the coating on the touchscreen displays. Apple's suggestion was to use a cloth dampened with water to clean their phones.

Those days are gone due to the Coronavirus outbreak. Apple has changed their guidelines and now say it is okay to use disinfecting wipes.

From Apple's Website:

Is it OK to use a disinfectant on my iPhone?
Using a 70 percent isopropyl alcohol wipe or Clorox Disinfecting Wipes, you may gently wipe the exterior surfaces of your iPhone. Don't use bleach. Avoid getting moisture in any openings, and don't submerge your iPhone in any cleaning agents.
