Brush Therapy TM by Joz TM cleans and restores brushes. Add 1 packet of Brush Therapy to 1 gallon of warm water. Let the brushes sit in the solution for 8 minutes. With larger thinner wooden backs soak the bristles only, in a shallow tray. Remove the brushes from the solution after 8 minutes and use a comb to loosen embedded hair. Rinse the brushes thoroughly with cool water. Shake out excess water and allow to air dry gently in a well ventilated area. Do not dry with heaters or fans. Repeat the process if needed. (Please note: Brush Therapy uses a three level cleaning process so it is important to leave the brushes in the solution for the full 8 minutes even though the solution will stop bubbling by then). If in doubt, please contact us. Use only as directed. Avoid contact with eyes or mucous membranes. Do not ingest. Minors should be supervised by an adult. Made in USA. If you want the Brush Therapy with the box, see #2539. Now available in a multi dose tub! See #1551.
