I’m sure the obvious answer is “no,” but if the phone is water resistant up to certain depths why wouldn’t I be able to give it a quick rinse with warm water and a drop of dish detergent (notwithstanding any damage the soap could do to the finish)? Wouldn’t the phone still work perfectly as the water would not penetrate the inner workings?
mall you need is a 12” square microfiber cloth, get it wet, wring it out well and wipe your iPhone down with it between your hands. The iPhone gets very clean this way. I use tap water and clean mine often this way regularly.
