In a fit of coronavirus caution, I used a wet wipe on my iPhone screen. Only after did it occur to me to check online, and I was told that doing so could damage the coating on the screen. The wet wipe liquid was on the front for a minute or two before I wiped it off.
This is my first iPhone (albeit used), so again I’m overcautious. How likely is it that I did any damage to the coating on the screen; I thought maybe it was warning against regular use, and this one mistaken use was fine. If the coating were damaged, how would I tell? Can I fix it? And is water and wiping sufficient for disinfecting a screen, which is what I was going for to begin with?
First of all, there is really no point in disinfecting a phone screen. Any process that would do a really good job is a bad idea.
Second of all, see the previous statement.
For just general cleaning purposes, a microfiber cloth that has a tiny amount of moisture on it will do a decent job. By “tiny” take what you think it a usable amount and cut it down by a factor of 10-50. If you see beads on the screen after the first wipe, you used waaaay too much.
(Yes, I know. They sell phone sanitizers. Shades of Hitchhiker’s Guide. But they sell a lot of things that are useless or harmful.)
I’ve used wet wipes on my iPhone and iPad many times with no issue. Why is it supposed to be problematic? (I use them not for any disinfectant purposes, but because it’s a simple wet cleaning cloth I have lying around.)
It’s called an oleophobic coating, which is oil resistant so that our fingers don’t leave streaks or smudges on the screen. Different manufacturers will use different substances to make their oleophobic compound so some are better than others but most agree that a strong concentration of isopropyl (or ethanol) alcohol will wear away at this coating. However, keeping it at 70% or under will be fine, (read negligible).
Keep in mind, it’s only a coating so it will eventually wear off if you keep rubbing your screen regardless of what solvent you use or don’t use, and this includes fingers.
