Default Re: Black stuff in gas tank

The biggest component in Lacquer thinner is MEK. Methyl Ethyl Ketone is in the same family of solvents as Acetone. Be very careful when using as they are both very flammable. both will remove lacquer paint upon contact so make sure you do not spill on the paint surface. Do not create sparks when working with it. We use to use brass scrapers and hammers in the painting industry so we could not create a spark.
Just some thoughts about safety when we talk about MEK or acetone,
By the way acetone is in finger nail polish remover,
