is acetone same as mineral spirits
I can't tell you the chemical difference, but acetone is very hot with a fast evaporation rate. Acetone will soften or lift many types of paint. Mineral spirits and paint thinner are pretty much the same thing. Both are slower dying, mild solvents for reducing enamels and varnish. When it comes to cost, paint thinner is usually cheaper. I always have a gallon of both in the shop and at home.
