How To Clean Sigma Brushes 1 Wet Wet the bristles of your makeup brushes under warm water. Avoid unnecessarily wetting the ferrule and handle. This can damage and losen the fibers and ferrule of the brush over time. 2 Wash Add a small amount of cleaning solution to makeup brush bristles. Using the textures of your Sigma Spa brush cleaning tool, swirl brush on the WASH texture to deep clean. 3 Rinse Continue to hold the brush downward, place makeup brush under running water and sweep brush back and forth on the RINSE texture on your Sigma Spa gadget. Repeat steps two through three until the water runs clear. 4 Squeeze Gently squeeze brush bristles with hand, microfiber towel or paper towel to remove excess water.
