Airbrush Restorer is a non-toxic super-cleaner/soaker that eats away the dried paint left in brushes. It works on even the most neglected and junked-up brushes. It is best used as a bath for soaking the spray gun or airbrush after painting. Airbrush restorer also works as a cleaner and helps remove dried paint. Hardened paint will loosen up and disolve a bit making it easier to remove. Make sure to thoroughly rinse with water after using Restorer to avoid any contamination of Colours. Restorer has a oil like texture which does not mix well with waterbased paints.
