Liquid Brush Softener Refill
Quickly refill your Liquid Brush Softener with this large refill bottle.
Liquid Brush Softener (or Gel Thinner) helps keep your brushes in optimal condition and will soften and prevent any hardening of the brushes in your 3-Step Liquid Base System. We recommend always picking up at least one bottle of Brush Softener, and then order refill bottles as needed - that way you'll always be able to continue using all of your brushes in your entire Liquid kit.
