Step 1 Run the bristles of the makeup brush under warm running water.





Step 2 Apply a small amount of shampoo OR Dawn Dish Soap to bristles and work into a light lather.





Step 3 Rinse bristles thoroughly under running water. You will notice that the water leaving the brush is tinted from old makeup.





Step 4 Continue rinsing until no color leaves the brush.





Step 5 Allow it to air-dry.How do you clean an old mascara brush?
i just kept rinsing it under really hot water til the water stopped running black, then left it in a cup of boiling water for like 5mins then rub some olive oil or sunflower oil onto the brush massage it in this loosens any mascara that may be left, then run under hot water again, or pour boiling water from the kettle over it.
The best way to remove the makeup is washing it with dawn dish washing soap. Then soak it in boiling water for at least five minutes, this way the brush will be sterilized, you should change your mascera brush about every four months so you need to make sure if you are using an old brush to sterilize it. After that just let it air dry.
i was told you can clean your brushes with vinegar. rinsing it with water before and after
YOU DON';T !!!!!!! just go buy a new mascara. A doctor once told me that if use the same mascara wand it could be carrying terrible bacteria ! beware
use nail polish remover and wait till its dry then use as usual
