Cleaning makeup brushes without damaging bristles means using lukewarm water, never wetting the metal ferrule, lathering with gentle shampoo, and drying them flat with bristles hanging off a counter edge.
Dirty makeup brushes are a breeding ground for bacteria that can cause breakouts and skin irritation. But the wrong cleaning method—hot water, soaking the handle, or scrubbing aggressively—can ruin bristles in one wash. The real trick is protecting the ferrule and glue while still getting every trace of foundation or eyeshadow out. Here is exactly how to do it, step by step, with advice from dermatologists and health sources.
Why Bristles Get Damaged During Washing
Most brush damage comes from water seeping into the ferrule—the metal band that connects bristles to the handle. Once moisture reaches the glue inside, it weakens the bond and bristles start shedding. Hot water is another culprit: it can warp synthetic fibers and dissolve natural-hair bristles over time. Aggressive twisting or scrubbing against a textured surface can also fray and break individual bristles. The fix is simple: keep the ferrule dry, use lukewarm water, and be gentle with the bristle tips.
Step-by-Step: The Safe Cleaning Method
The American Academy of Dermatology and Cleveland Clinic both recommend this approach for brushes with natural or synthetic bristles.
- Wet only the bristle tips under lukewarm running water. Keep the ferrule and handle completely dry.
- Apply a small amount of gentle shampoo, clarifying shampoo, or dedicated brush cleanser to your palm or a cleaning mat.
- Gently swirl and massage the bristles in the cleanser. Do not scrub hard or twist the brush.
- Rinse under lukewarm water until the water runs completely clear—no suds remaining.
- Gently squeeze excess water from the bristles with your fingers. Do not pull or tug.
- Reshape the brush head to its original form with your fingers.
- Lay the brush flat with the bristle end hanging slightly off the edge of a counter or towel. This keeps water from draining back into the ferrule as it dries.
after drying overnight, the bristles should feel soft, look clean, and hold their original shape with no loose fibers.
Mistakes That Ruin Brushes
- Hot water: damages fibers and loosens glue. Use lukewarm water only.
- Wetting the ferrule: water inside the metal band is the number one cause of shedding and brush breakup.
- Flat drying is the only safe method.
- Aggressive scrubbing: twisting or rubbing bristles against a textured mat can fray them permanently.
- Drying on a flat towel without support: trapped moisture underneath promotes mildew. Always let bristles hang off an edge.

How Often Should You Clean Them?
The American Academy of Dermatology recommends cleaning makeup brushes at least once a week if you use them daily. Brushes used around the eyes or for liquid products (foundation, concealer) need the most frequent cleaning. Powders can stretch to every other week, but weekly is the safest routine for skin health and brush longevity.
FAQs
Can I use dish soap to clean makeup brushes?
Dish soap is too harsh for most brush bristles and can strip natural oils from natural-hair brushes, leaving them brittle. Stick with gentle shampoo, clarifying shampoo, or a mild unscented soap instead.
What is the best way to dry makeup brushes after washing?
Lay them flat with the bristle end hanging off the edge of a counter or tabletop. This allows air to circulate around the bristles while keeping the ferrule dry. Never dry them upright in a cup or jar.
How do I know if my brushes are clean enough?
Rinse until the water runs completely clear and no suds remain. After drying, the bristles should feel soft and look uniformly clean. If you see residue or smell old product, wash again.
