Makeup brushes don’t only work well to apply eyeshadow and blush. In fact, they often put lots more on your face than you may realize.
The dirty problem
Every time you use them, your cosmetic brushes collect makeup residue, dead skin cells, dirt and skin oils — all of which can become a nice breeding ground for bacteria. If your makeup brushes are not cleaned regularly, that goop and bacteria gets rubbed back on to your face.
What’s the solution? The good news is that you don’t need to constantly replace your brushes. Instead, you can just clean them — carefully. Here’s how.
When should you clean your brushes?
So how often should you clean your dirty makeup brushes? Recommendations vary.
Brushes used to apply liquid cosmetics (like foundation and lipstick) should be cleaned daily, according to Empire Beauty Schools, while brushes for dry makeup (such as blush and eye shadow) can be cleaned weekly. Makeup brands like CoverGirl, Benefit Cosmetics and Estee Lauder also recommend cleaning the brushes once a week.
But not everyone keeps this schedule. For example, top Austrialian makeup artist Napoleon Perdis says to disinfect brushes with a brush cleaning spray after every use, then to deep clean your brushes every two to four weeks. “Wet your brush with warm water and massage a small dollop of shampoo into the bristles. Rinse thoroughly and then work just a bit of conditioner through the brush and rinse again.”
If someone else has used your brush, wash it immediately afterwards — or, at least, before you use it again. (Read about how one woman believes she caught a major infection from a dirty makeup brush, which led to her becoming paralyzed.)
Finally, if your brush has visible makeup residue and isn’t soft, no matter how long it’s been since its last bath, it’s time to give it a good wash.

The baby shampoo method
Beauty and lifestyle blogger Aly Walansky shared with us her favorite brush cleaning method:
“Put a few squirts of baby shampoo mixed with warm water in a soup bowl in your sink. Rinse off the brushes first with warm water, then simply place them in the bowl and let them soak for a few minutes.” When they’re clean, she says, rinse them off again, making sure the water runs clear, to be positive you don’t have any excess residue.
Olive oil and dish soap
For another take, here is Michelle Phan’s “Ultimate DIY brush cleaner” how-to:
Pour 2 parts basic dish soap on to a plate along with 1.5 parts extra virgin olive oil. (The soap cleans and disinfects, while the olive oil works as a conditioner on the bristles.)
Stir your makeup brushes one at a time through the mixture, using a circular motion. Next, rub the brush back and forth on your hand to release the makeup and oils from the brush.
Then there’s a completely different way to sanitize — but not wash — your brushes: the Brush Medic, which uses UV-C Sterilizing LED technology to kill most viruses, germs, microorganisms in less than 10 minutes. Another brand offering UV sterilization is Salon Sundry.
No matter what soap or mixture you use, don’t let the base of your brush — where the bristles meet the handle — get wet. Doing so can loosen the glue holding the brush together, and the bristles may get loose and fall out. (It could also rust any metal.)
Also, take your time and be gentle. When washing your brush, don’t push hard or bend the bristles, so you can maintain the shape of each brush.
After cleaning each brush, gently re-shape the bristles before drying.
Drying your brushes
Gently dry and blot your brushes with a paper towel, according to Michelle Phan, then hang them upside down (bristles facing down) to dry completely.
Estee Lauder suggests you lay brushes flat to dry. “Place at edge of table or counter with bristles pointing out to air-dry completely. Avoid drying upright, which can cause bristles to spread and handles to crack.”
Never let your brushes dry on a towel, warns Bobbi Brown, as the bristles can become mildewed.
Don’t forget your brush handles
No matter which method you use to clean the brush bristles, don’t forget to clean your brush handles, too!
Clean them by putting rubbing alcohol or full-strength white vinegar on to a napkin or paper towel, or use a disinfectant wipe (such as those from Clorox or Lysol) and completely wipe down each brush handle.
By taking just a few moments each week to cleanse your cosmetic brushes, you can not only apply makeup the way it was intended to be seen, but keep your skin healthy and vibrant.
