NEVER USE TURPS to clean your brushes instead use artists quality LINSEED OIL.
FINALLY with a little water, slurry up your brush on a cake of “THE MASTER’S” SOAP FOR ARTISTS; available in most PROFESSIONAL ARTISTS SUPPLY SHOPS.
When all the paint has been gently removed, rinse the brush well in clean water, smooth the bristles and leave to dry flat.
Not only does this method preserve your precious brushes but unlike TURPS, it is NOT TOXIC and it is A GOOD CHOICE FOR OUR PLANET.
Happy painting!
