Disinfecting only the outside of your phone case is ineffective as bacteria can linger between your phone and its case. Always remove your phone to sanitize the case thoroughly. Be sure to target germs on both the inside and outside of the silicone case for the best results. Rub a disinfecting wipe all over the inner and outer surface of the case. Let the case sit for several minutes to dry. When you are sure that it is dry, put your phone back in. This is also a good way to disinfect your phone case quickly if in comes in contact with germs. Apply rubbing alcohol to a cotton swab or cotton ball. Swipe the alcohol-soaked cotton over both the inner and outer surfaces of your phone case. This will kill bacteria lingering on the case.  The rubbing alcohol should dissipate within seconds of applying it. Make sure there is no lingering moisture in the case, as this could damage your phone. Wait a few extra minutes to ensure the case is totally dry before putting it back on your phone. Strong, concentrated cleaning products can cause damage to silicone items. Refrain from using any harsh cleaning chemicals on your phone case. These may include:  Household cleaners Window cleaners Cleaners with ammonia Cleaners containing hydrogen peroxide Aerosol sprays Solvents
