Always clean your brush immediately after use. Pour nailbrush cleaner solution into a glass container. The cleaning solution is usually available at beauty supply stores. Swish the brush in the cleaner solution until visibly clean. Remove liquid from the brush by dabbing the bristles on a paper towel. Try not to press the brush too hard on the paper towel as the bristles are delicate and can come off if too much force is used. With your fingers, gently reshape the brush and allow to dry. Optional: Apply a little cuticle oil or olive oil on the tip of the brush after you have finished cleaning it. This will keep the bristles soft. To clean the oil off, run the brush through warm, soapy water.
