Bristle Magic is a cleaner and brush conditioner that cleans oil and acrylic paints from paintbrushes. You will love that even dried-on paints can be removed with Bristle Magic. Bristle Magic is a concentrated product . For oil painters, we recommend using Bristle Magic full strength. For acrylic painters, we recommend diluting with water to the strength needed, depending on how long your brushes have been left with paint on them. When mixed with water, Bristle Magic turns into a cream colored solution. That's OK!
