Begin by running your brushes under lukewarm water, rinsing out all of the residual makeup. Try to focus on the actual bristles while avoiding the part of the brush where handle meets the head, as this can loosen the glue over time
Fill a bowl with lukewarm water and a squirt of shampoo, and gently swirl your brush tip in the water. If you need to, you can also swirl the brush in the palm of your hand to work up a lather.
Rinse the brush tip under running water once again. Repeat steps two and three until the water runs clear from the brush,
Use a cloth to wipe your brush clean, reshaping the bristles as you go.
