How to Clean Makeup Brushes (The Right Way)
By Viktoria @vioda.makeup ·
Dirty brushes ruin your makeup and your skin. Here's the right way to clean them—and how often you actually need to.
How often to clean brushes, what to use, and the drying technique that prevents damage. A complete guide.
Why Cleaning Your Brushes Matters More Than You Think
Makeup brushes collect product buildup, dead skin cells, oils, and bacteria every time you use them. That accumulation degrades your makeup application—colors look muddy, blending gets streaky, and products don't apply evenly. Worse, dirty brushes can cause breakouts, irritation, and even infections if bacteria builds up over time.
A study published in the Journal of Applied Microbiology found that cosmetic brushes can harbor significant bacteria after just a few uses. You don't need to be paranoid, but regular cleaning is non-negotiable if you care about your skin and the quality of your makeup.
How Often You Actually Need to Clean
Brushes that touch liquid or cream products—foundation brushes, concealer brushes, lip brushes—should be cleaned after every 2–3 uses. These products are moist environments where bacteria thrive. Eye brushes used for dark or pigmented shades should be spot-cleaned between uses if you're switching colors, and deep-cleaned weekly.
Powder brushes—blush, bronzer, setting powder—can go a bit longer, about once a week for regular users. Sponges and beauty blenders are the worst offenders for bacteria and should be cleaned after every single use. Yes, every single use. They absorb liquid product and stay damp, which is a bacteria playground.
Deep Cleaning Method
Wet the bristles under lukewarm running water, pointing down so water doesn't get into the ferrule (the metal part that connects bristles to the handle—water there loosens the glue and causes shedding). Apply a gentle cleanser to the bristles. You can use baby shampoo, a dedicated brush cleanser, or even a gentle bar soap.
Swirl the brush on your palm or a textured silicone mat, working the cleanser through the bristles until the water runs clear. Gently squeeze out excess water with a clean towel, reshape the bristles, and lay flat to dry on a towel with the bristles hanging off the edge of a counter. Never dry brushes upright in a cup—water drips into the ferrule and destroys the brush.
Quick Spot-Cleaning Between Washes
For a fast clean between uses, spray a brush cleaner or 70% isopropyl alcohol onto a paper towel and swirl the brush until no more color transfers. This removes surface product and sanitizes without a full wash. It's especially useful for eyeshadow brushes when switching between colors during the same look.
Dedicated brush cleaning sprays from brands like Cinema Secrets and e.l.f. evaporate quickly and leave brushes ready to use in seconds. Keep one on your vanity for daily maintenance between deep washes.
How to Make Your Brushes Last Longer
Quality brushes can last years with proper care. Beyond regular cleaning, store them upright in a cup or brush roll—not loose in a makeup bag where bristles get crushed. Avoid using hot water, which can melt the glue in the ferrule. Never pull on bristles to check if they're secure; the fibers are delicate and won't survive rough handling.
If a brush starts shedding despite good care, it's time to replace it. Natural hair brushes typically last 3–5 years; synthetic brushes can last even longer. The cost per use of a well-maintained quality brush is pennies—far cheaper than buying replacements every few months because you skipped cleaning.
