Yes! Love your Cocobrush and your Cocobrush will love you back. Cocobrush bristles should be rinsed thoroughly with hot water before and after every use to wash away debris and bacteria. Use steamy water (watch your hands!) for the best sanitization. After brushing and rinsing, store your Cocobrush upright to air dry, which helps reduce bacterial growth. Take care of your Cocobrush, and it will last you about three-to-four months until the next replacement.
