THE FIRST CLEAN: We recommend cleaning your new Sigma brushes by using a brush cleanser or mild shampoo, prior to your first use. When cleaning your brushes be careful not to fully submerge or wet the brush beyond the metal ferrule, as this may cause damage to the wooden handle. THE SPOT CLEAN: Daily spot cleaning can be done by using a brush cleanser solution and a soft tissue. Add a small amount of brush cleanser to the tissue and gently wipe the bristles back and forth until they are clean. nTHE DEEP CLEAN: Deep cleaning is recommended once a week. Brush cleanser or mild shampoo is ideal for washing, sanitizing and conditioning brushes. To deep clean your brushes, soak the bristles in a brush cleanser and warm water solution until product is removed from the bristles. Gently wipe the brush back and forth, squeezing out any excess water. After the bushes are clean, we recommend drying and shaping them using the Sigma Beauty Dry n Shape system. This patented system guarantees to dry and shape any brush within 4 to 6 hours!
