Pull out your used makeup brushes
To keep bacteria from building in your makeup brushes, beauty pros recommend washing your tools at least once a week.
Add baby shampoo
There are plenty of makeup brush cleaners on the market (Try: Clinique Makeup Brush Cleaner), but you may have a great solution already in your bathroom. Baby shampoo will cleanse your tool of makeup without damaging the bristles. Place a pea-sized amount onto the brush.
Wash
Put the makeup brush with baby shampoo into shallow water. Ideally, you want to avoid getting water in the base of the brush. Pro tip: Using a small bowl or mason jar will help to save water and keep you from having to clean your skin after.
Pat dry
Gently pat the brush dry on a paper towl or lint-free cloth.
Leave to dry
Beware: It will take at least half a day for your brushes to dry completely. Lay them flat, so the water doesn't sink into the base, rusting your brushes.
Use your clean tools
Now, your tools are ready to be used again!
