If you're noticing that your brush is starting to collect gunk, it's probably time to give it a good cleaning. Here's how to clean the gunk out of your brush:
1. Start by running your brush under warm water. This will help loosen up any build-up that's clinging to the bristles.
2. Next, add some shampoo or soap to the bristles and work it into a lather. Really work the cleanser into the bristles, getting rid of as much gunk as possible.
3. Rinse your brush thoroughly under warm water until all of the soap is gone.
4. Finally, allow your brush to air dry completely before using it again.
