Brush Cleaning How-To: 1. WASH- Add 1-3 pumps of SigMagic™ Brushampoo™ to brush bristles, depending on brush density and product buildup. While holding the brush downward, add water to brush bristles only, avoiding ferrule and handle, and swirl brush on Sigma Spa® cleaning gadget. 2. RINSE- Rinse thoroughly with warm water to remove makeup residue and soap. 3. RESHAPE- Remove excess water and insert into a Sigma Dry'n Shape® Tower or reshape brush bristles and lay flat to dry.
