This brush belonged to my daughter-in-law's grandfather and she gave it to me so I was really sad when I thought I had ruined it. I put it to soak in some rubbing alcohol over night to try to dissolve the acrylic paint and it worked! It broke it down enough that with the help of some mild handmade soap and a nailbrush, I was able to remove all but a slight stain left from the paint.
