Q: I have a few paintbrushes that have hardened oil paint stuck in the bristles. In which solution should I soak them?
A: There is a great soap called The Masters Brush
Cleaner and Preserver that really works on brushes that have hardened
with oil and acrylic paint. It is sold in a thin, flat, round plastic
container that has old-fashioned, dark brown lettering. It is also sold
in a bar-shaped cake and in a tub. Most art stores carry it, including
*** Blick, which also carries it online.
