Your Makeup Brushes Are Dirtier Than You Think—Here’s How to Clean Them Properly

Like it or not, your makeup brushes do more than give you that flawless blend—they can also be a breeding ground for bacteria if you don’t clean them properly and regularly.

Experts recommend giving them a good wash at least once weekly or every 10 days, as leftover product, dirt, and oils build up on the bristles with each use.

But don’t worry, it’s not as complicated as it sounds. Here’s a simple guide to keeping your brushes clean and your skin safe from breakouts and irritation.

Start with a Lukewarm Rinse

Start by rinsing the brush bristles under lukewarm running water, aiming the water downwards to avoid loosening the glue that holds them. This helps remove surface-level product and preps the brushes for a deeper clean. To keep the glue intact, avoid getting the ferrule (the metal part) wet.

Lather Up with a Gentle Cleanser

Squeeze a small amount of gentle cleanser (baby shampoo or a brush-specific cleanser works great) into a shallow dish. Gently swirl each brush in the solution, ensuring the cleanser penetrates the bristles to lift out stubborn residue. For tougher buildup, use your fingers or a silicone brush cleaning mat to work the product through.

Swish and Rinse Thoroughly

Once lathered, rinse the brush thoroughly under lukewarm water, gently squeezing the bristles until the water runs clear. Repeat if necessary, but don’t pull or tug on the bristles, as that can damage them. Pat the brushes gently on a clean towel to remove excess moisture.

Reshape and Let Them Air-Dry

This laid-back look works for almost any occasion. Section off the top half of your hair, twist it into a small, messy bun, and secure it with a hair tie or pin. It creates a casual, boho vibe and looks more put-together than it really is.

Lastly, Pro Tips to Keep Brushes and Skin Healthy

Beyond the basic cleaning steps, a few extra practices can help keep your brushes in tip-top shape and your skin clear. Experts recommend deep cleaning your brushes at least once a week, especially if you use them daily, to prevent product buildup and bacterial growth.

When washing, be mindful not to soak the handles, as water can loosen the glue holding the bristles. For a quick refresh between deep cleans, a brush cleaner spray can remove light product residue without needing water.

If you use natural hair brushes, be extra gentle and opt for a mild, sulfate-free cleanser to maintain their softness.

And don’t forget—brushes have a lifespan, so replace them every one to three years to ensure they stay effective and hygienic.
