I have used spirit stain/dye for years now, and have had a supply of denatured alcohol, to thin and clean brushes with, now I'm getting low on it, and cant buy it because of the ban in California, what other thinner can I use thats safe to use in a confined space? I'm considering switching to water-soluble dye after reading the article on it from the latest magazine, but I like the alcohol based dye, it dries faster and it's already in a liquid state, any help is appreciated.
