I picked up some of this paint thinner the other day at Lowes thinking I would save a couple bucks and be “green” at the same time. Big mistake, this stuff is nothing like paint thinner. I was going to use it to clean up some greasy parts and while it did dissolve some of the crud it just didn’t have the solvent action of mineral spirits. I tried to find a MSDS on it to find out what’s in it but couldn’t find anything. It almost seems like it is kerosene based because it leaves an oily film and takes forever to evaporate. I think kerosene or diesel would actually do a better job. I can’t imagine using this stuff to clean a paint brush.
