To clean makeup brushes, begin by gently wetting the bristles of your brushes with warm water. Stiles recommends using a soapy cleanser and hot or warm water to deep-clean brushes. Swirl the brush onto the bar of a gentle soap (like baby shampoo or a dedicated brush cleanser) or into a bowl of soapy water. Gently massage the bristles with your fingers or a cleaning mat until the lather runs clear. Rinse thoroughly under warm water, reshape the bristles, and lay them flat or hang them upside down to air dry completely.
Makeup sponges also require regular cleaning, ideally after every few uses. Wet the sponge completely under warm running water. Apply a small amount of liquid soap or sponge cleanser directly to the sponge. Squeeze and massage the sponge repeatedly under running water until all makeup residue is released and the water runs clear. Gently squeeze out excess water with a clean towel and allow it to air dry completely in a well-ventilated area.
