So, I know the iPad screen should not be cleaned with windex (or so I've read) but when I was home over the holidays good ol' mom tried to be helpful and wiped down my screen with a windex covered cloth (I witnesses the crime ) and this cloth was pretty damp (not soaking). Is it true that over time this will break down the protection of the screen and glass itself, or is that with repeated use? I'm not too worried about this one time (even though I have occasionally used eye glasses cleaner, but it has no ammonium and is fairly weak) but wiped it down with a little water on a microfiber cloth just to make sure and was just curious in general. Should I get a screen protector just in case? (No, I am not currently using protection with my iPad) Thanks!
