Wet your makeup brush with lukewarm water and swirl it onto the Brush Cleaner. In a circular motion, gently swirl the bristles onto the beaded surface on the inside of the lid until all makeup has been removed from the brush. Rinse the brush, squeeze out excess water with a towel or absorbent paper and repeat as necessary. Reshape the brush and allow to air dry completely before use. Finally, rinse the Brush Cleaner and let dry before storing. This product can also be used to clean makeup sponges.
