Input: Text: i bought a scanner on ebay, and collected it today. having installed and tested it, i decided the lid needed a bit of a clean. i know, i have just the thing, a can of that foam cleaner stuff. it's in my garage in a grey aerosol. i grabbed it and gave the top a quick spray. it was then that i noticed i hadn't grabbed the cleaner, but the can of grey primer next to it.  
i've managed to clean most of it off but it still looks a right mess.

TIFU by not reading a label.
