I'm sorry, but I've NEVER had brake cleaner remove paint (or powder coat, or attack plastic or rubber) as it's usually the first thing I spray on something to clean it before working on it if it's greasy/dirty. Used it to clean the stop solenoid on the fuel pump of my 4400, this spring, before removing it. I'm sure I got some on the plastic panels in the process, & it didn't remove the paint on the pump, or discolor the plastic panels. (that I could see). Even using it for cleaning brakes (gasp!) it won't take paint off backing plates, caliper mounts, or the body where it gets sprayed (notably on door hinges prior to lubricating with anti-seize compound). It's also the only thing I ever found that will remove anti-seize compound plus it'll CLEAN sand-blasted glass (this amazed the guy I was working for at the time, as he'd been in the glass biz most of his life & his "method" was lots of water & glass cleaner 3-4 times if not more to remove the streaking... the brake cleaner turned the glass about 70% translucent on contact, water won't do that, & cleaned it completely in one pass leaving no streaks).
