Your foundation looks patchy. Your blush is pulling color from last week. Your blending brush smells like something that shouldn’t be on your face.
The culprit? Dirty makeup brushes. And if you’re not cleaning them regularly, you’re not just compromising your makeup application, you’re putting your skin at risk.
Here’s everything you need to know to clean your brushes properly and keep your makeup looking like it was done by a pro.
Why Cleaning Your Makeup Brushes Actually Matters
Every time you use a brush, it picks up more than just a product. Oils, dead skin cells, bacteria, and old pigment build up in the bristles over time. Dirty makeup brushes are a breeding ground for bacteria and that bacteria can cause acne breakouts, rashes, fungal infections, E. coli, or even staph infections, which can be very serious.
Beyond skin health, dirty brushes are also the number one reason makeup doesn’t apply smoothly. Leftover product means your makeup shades won’t stay true to their color, and dirty bristles make blending harder — resulting in a muddy, uneven finish.
How Often Should You Clean Your Makeup Brushes?
Dermatologists recommend washing your makeup brushes every 7 to 10 days to protect your skin and kill harmful bacteria. But frequency also depends on usage:
- Foundation and concealer brushes – once a week (they carry the most product and bacteria)
- Powder, blush, and bronzer brushes – every 1–2 weeks
- Eyeshadow and liner brushes – every 7–10 days
- Sponges and beauty blenders – ideally after every use, but aim for at least once a week
What To Use To Clean Makeup Brushes
You don’t need expensive products. Some of the most effective cleaners are already in your home:
- Gentle face cleanser or baby shampoo – the go-to recommendation from dermatologists. Anything safe enough for your face is safe enough for your brushes.
- Liquid dish soap – effective at removing caked-on product residue, but avoid overusing as it can be drying on bristles
- Castile soap – a gentle, vegetable-based option that cleans thoroughly without stripping bristles
- Vinegar and lemon – a natural disinfectant combination that kills germs and leaves brushes smelling fresh
- Specialist brush cleaner – worth the investment for a deeper, conditioning clean, especially for dense or heavily used brushes
Step-by-Step: How To Clean Makeup Brushes
Step 1 – Rinse the Tips: Rinse only the tips of your brushes under lukewarm running water to remove residual makeup. Avoid submerging the whole brush head – this will eventually dissolve the glue that connects the bristles to the handle.
Step 2 – Lather and Swirl: Apply a small amount of cleanser to your palm or a silicone cleaning mat. Gently swirl the brush bristles into the cleanser using circular motions – you’ll see makeup and dirt running out as you work up a lather.
Step 3 – Rinse Until Clear: Keep rinsing under lukewarm water and repeat the shampooing process until the water running from the brush runs completely clear – that’s the sign all residue is gone.
Step 4 – Squeeze and Reshape: After cleaning, squeeze out excess water from the bristles using clean, dry paper towels, then gently reshape the brush head back to its original form.
Step 5 – Dry Flat: Lay your brushes flat to dry on a towel with the tips hanging off the edge of the counter. Never dry brushes upright – water will run down into the handle and loosen the glue over time.
Common Mistakes To Avoid
- Soaking the full brush – always wet tips only, never submerge the handle or metal ferrule
- Drying upright – always flat, always with tips off the counter edge
- Using alcohol regularly – while alcohol seems like a quick disinfectant, it dries out bristles, weakens the ferrule glue, and damages brushes over time
- Sharing brushes – never share your makeup brushes with anyone else, especially at a time when skin infections are on the rise
Clean brushes aren’t just a beauty habit. They’re a skin care habit. Once you make it a routine, you’ll notice the difference immediately – smoother blending, truer color, and skin that isn’t fighting a bacteria battle every morning.
Your brushes work hard for you. Return the favor.
FAQs
Q1-What is the best thing to clean makeup brushes with?
A gentle face cleanser or baby shampoo is dermatologist-recommended – anything safe for your skin is safe for your brushes. Castile soap is another excellent option: gentle, effective, and budget-friendly.
Q2-Can you use Dawn dish soap to clean makeup brushes?
Yes, Dawn works well for removing stubborn, caked-on products. Use it sparingly though – its degreasing formula can dry out bristles over time. Follow up with a drop of conditioner to keep bristles soft.
Q3-How do I deep clean my makeup brushes?
Wet the tips with lukewarm water, swirl into cleanser on your palm or a silicone mat, lather in circular motions, then rinse until water runs completely clear. Repeat if needed for dense brushes. Lay flat to dry overnight.
Q4-How do professional makeup artists clean their brushes?
Pros use a two-step system: a quick-drying brush spray between clients for same-day use, and a thorough shampoo wash at the end of the day. They never dry brushes upright and always reshape bristles before drying.
