As hobbyists, we absolutely punish our brushes. Show them some love and respect by keeping them clean and conditioned the proper way. I highly recommend using The Masters brush cleaner. I have been using this product for nearly a year now and have seen incredible results. My sable bushes have maintained their original shape and point, the bristles remain soft and supple without splitting and the brushes are lasting a very, very long time. This is a great way to extend the life of your brushes with very little expense.
It is simple to use. After a full painting session simply wet your brushes in warm water and then lather them in the cream and rinse. Easy enough to do after every painting session. I have tried many products, but this is the most respected and recommended brush cleaner available and I have loved it.
The brushes we use make a critical difference in the quality and enjoyment of our painting - don't neglect them.
