Cleaning your makeup brushes is a vital part of wearing makeup. Maintaining pristine brushes is not only hygienic, it also allows for better makeup application and increases a brush's life span. For bareMinerals brushes -- and most other brands -- it's advised by the bareMinerals beauty educators to thoroughly wash them about once a week.
If you're doing a makeup application with multiple eye shadow colors, your brush will need to be cleaned between each color. Spritz bareMinerals Quick Change Brush Cleaner onto a paper towel. Wipe your dirty brush onto the moistened paper towel, in a quick, circular, downward motion on the bristles. Continue applying your makeup once the brush is wiped down.
Use the same cleaning method once you're done applying your makeup, just to keep your brushes somewhat clean throughout the week before you deep clean them.
In lieu of bareMinerals Quick Change Brush Cleaner, use another gentle makeup brush cleaner spray, or a diluted mix of baby shampoo and water in a spray bottle.
For the weekly deep cleaning of your bareMinerals brushes, put them under lukewarm running water in a clean sink. BareMinerals makes a product called Well-Cared for Brush Conditioning Shampoo, but the company also says that baby shampoo will do the trick. Put a dime-size amount of shampoo into your hand and swirl the brush into it, ensuring it lathers throughout all the bristles. Rinse the brush in running lukewarm water. Once completely rinsed, squeeze the bristles to remove most of the water. Leave the brush on its side to dry overnight on a paper towel. If you don't lay it flat, water could get into the base where the bristles are and expand the brush, potentially resulting in bristles falling out.
Store brushes so they stay hygienic between uses. Place them bristle end up in a jar with coffee beans, beads or marbles in the bottom so the brushes can be positioned to not touch each other.
