You may know when it’s time to give your makeup brushes a good scrub (at least once a week), but some unsuspecting tools fly under the radar. For example, do you know how to clean your hot tools? What about ridding your hairbrush of debris? And finally: Did you know your dry brush can get gunky? But dry brushing is also an excellent physical exfoliant for the body since those bristles can buff away excess dead skin cells from the surface of your skin. As the brush manually lifts that dead skin, those flakes can become lodged in the bristles and build up—so, yes, you need to give your dry brush a good clean every once in a while, even though you’re sweeping over dry skin. The good news is, cleaning your dry brush is super easy: Simply scrub the tool with warm water and a gentle soap or makeup brush cleanser. Make sure to set it out to dry with the bristles facing up so they don’t collect any mildew or bacteria. If you’’d like to clean your dry brush in between washes, feel free to mist it with a tea tree solution (1 part tea tree oil, 2 parts water), as the essential oil has antifungal and antibacterial properties. In terms of how often you should clean it, it really depends on how often you use it. Some practice full-body brushing daily or every other day, which means you may have to clean the tool more regularly (like once a week). Others only do it once or twice a week, and if you’re dry brushing your face, you definitely shouldn’t make it a daily habit (that’s way too much exfoliation for your delicate facial skin). If you do have space between your sessions, you may only need to clean the tool every few weeks or so. No matter what, make sure you carve out some cleaning time every once in a while or replace the tool after its prime. Here’s a list of our favorites, if you’re in the market.
