The paint is another subject altogether.
Sometimes you can scrub it off with a scrub pad.Nothing to abrasive though.The idea is to remove the paint and not damage the surface.
If you use a razor blade you can scrape it,again without damaging the surface it's stuck on.
A little lacquer thinner maybe.
Some use denatured alcohol or mineral spirits.I always ended up with the lacquer thinner.
I know this sounds odd,but after 35 years of this stuff I know it's true,and that is.It matters what kind of rag you put the lacquer thinner or alcohol on to try and clean something.Don't grab a paper towel,won't work or a tshirt rag,again it will not work.Use a terry cloth towel.It has something to do with the way it absorbs to quickly into the rag and then there is none of the chemical left on the surface to actually do the cleaning.
As well when you finish using one of these rags with lacquer or alcohol.Leave the rag outside and the odor and chemical will evaporate.If you throw it in your washing machine it will stink up the whole place.Leave it outside.It will evaporate and then you can toss it in with the other rags to wash.
I found this new product called De-Solv-it. Never tried it on paint,but it's AWESOME for stickers, labels,and black marks on floors.
