Clean your Liner Brush with odorless thinner by swirling it around in clean thinner. Once it is completely clean, lightly roll the brush hairs on a soft paper towel until dry. Then take some “Orange” hand cleaning soap with pumice and put this onto one of your index fingers. Thoroughly massage the liner brush hairs for several minutes until the natural color of the hairs have returned. Don’t forget to clean all the way up to the metal ferrule. Clean in thinner, roll dry on paper towel and store with a small amount of baby oil in your liner brush hairs.
