Overheard a kid at the makerspace talking about using lithium grease on his cyberdeck case

I was at the local makerspace in Portland last Tuesday helping a friend with his 3D printer, and I overheard some young guy telling his buddy he used lithium grease on a polycarbonate cyberdeck case. I had to step in and stop him. That stuff eats through certain plastics like acid. He was about to ruin a months worth of work. Has anyone else seen someone make this kind of mistake with lubricants on their builds?

Saw a guy at my local space try WD-40 on his PLA prints once. He learned the hard way it makes the plastic all cloudy and brittle.

WD-40 has acetone in it which is basically nail polish remover for plastic.
