Don’t ask me how I found this out, but if you’ve got crap on your iPhone screen that won’t come off with a tissue, giving your iPhone a good lick or two and then giving it another go with a tissue is a win every time.
Yes, it is gross. I support iPhones, and if our users are going to do this, then I’m going to do a bulk order of isopropyl wipes. I mean, where else have their tongues been?
Icky.
(Isopropyl is an alcohol, which is good at cleaning all sorts of computer devices. I use it for cleaning devices before they go back to the customer).
