Rinse bristles under lukewarm water. Avoid getting ferrule wet as much as possible.
Use baby shampoo or your favorite makeup brush cleanser. The only antibacterial soap gentle enough to use on makeup brushes is Dawn antibacterial soap (use this if you want to disinfect). We also recommend a cleansing palette/glove. If you do not have a palette or glove, you can use the palm of your hand.
Squeeze soap into cleansing palette and mix with lukewarm water.
Swirl bristles into mixture. Keep swirling bristles in cleansing palette until all of the makeup product is off of the bristles and the water appears clear.
Fold a clean drying towel 1/4 over to create a ledge.
Place brushes bristle-side down so that water can drip toward the tips of the bristles and onto the towel. This helps prevent water from dripping into the ferrule and onto the handles. Try your best to avoid getting the ferrule and crystals wet. Allow brushes to air dry.
To shine the crystals use jewelry cleaner and a lint free microfiber cloth.
Dip microfiber cloth into jewelry cleaner.
Polish the crystals by rubbing the cloth up and down the handle of the brushes. Air dry.
Repeat this process until each brush is clean.
