Developed by Brian of Art Party Unlimited and made in small batches here in the studio.  This gentle formula does wonders for your oil painting brushes.  Cleans and conditions in one step.  We've found it can also effectively revive brushes with dried-on oil paint! A new batch of the big blocks is coming soon. See Brian's demo on our YouTube channel.
