Clean makeup brushes apply product more evenly and are easier to inspect for wear. The reliable method is to wash only the bristles with lukewarm water and gentle cleanser, rinse completely, reshape, and dry flat with the brush head over a counter edge.
The safest routine is simple: rinse only the bristle tips with lukewarm water, work in a gentle brush cleanser or gentle clarifying shampoo, rinse until the water is clear, reshape the head, and dry the brush flat with the bristles hanging over a counter edge. Keep water away from the ferrule and handle, where prolonged moisture can weaken the brush.
That method works for most everyday powder, blush, foundation, concealer, and eye brushes. It also avoids the improvised treatments that can leave residue or damage a brush, such as olive oil, hand sanitizer, bleach, vinegar, or high heat. The guide below explains what to use, how often to clean, and when a brush is no longer worth saving.
What You Need
- A sink with lukewarm running water
- A dedicated brush cleanser or a small amount of gentle clarifying shampoo
- A clean towel or clean paper towel
- A clean, ventilated surface where brush heads can hang over the edge
Check the brush maker’s care instructions first, especially for expensive natural-hair brushes or tools with unusual finishes. A textured silicone cleaning mat is optional. If you use one, move the bristles gently rather than grinding or splaying them against the texture.
How to Clean Makeup Brushes Step by Step
- Rinse the tips. Hold the brush with the bristles pointing down. Run lukewarm water over the bristle tips, turning the head so all sides become wet. Do not submerge the whole brush or direct water into the ferrule.
- Add a small amount of cleanser. Put gentle brush cleanser or gentle clarifying shampoo in your palm. Swirl the wet bristle tips lightly through it. Use your fingers to massage dense bristles without pulling them.
- Rinse thoroughly. Keep the brush angled downward and rinse the bristles under lukewarm water. Repeat the cleanse only if visible product remains. Continue rinsing until the water is clear and the brush no longer feels soapy.
- Remove excess water. Gently squeeze the bristles from the ferrule toward the tip with a clean towel or paper towel. Do not twist or wring the head.
- Reshape the brush. Use clean fingers to return the damp bristles to their normal profile. This is especially useful for tapered eye brushes and fluffy powder brushes.
- Air-dry it flat. Place the handle on a clean counter or folded towel with the entire brush head extending beyond the edge. Let it dry completely before use or storage. Do not stand a wet brush upright, because water can run toward the ferrule.
This sequence follows the practical method published by the American Academy of Dermatology. Plan the wash for a time when the brushes can air-dry undisturbed; overnight is convenient, but the actual drying time depends on head density, room airflow, and humidity.
How Often Should You Wash Them?
The American Academy of Dermatology recommends washing makeup brushes every 7 to 10 days. Treat that as a useful baseline, then adjust to the way each brush is used. A brush that repeatedly picks up cream or liquid makeup may show buildup sooner than one used occasionally with loose powder. Clean a brush before changing between products when cross-contamination would matter, and do not share personal makeup brushes.
| Situation | Best decision | Why |
|---|---|---|
| Regular personal use | Use a 7-to-10-day washing routine | It creates a memorable baseline before heavy product buildup develops. |
| Switching strong eye colors | Use a labeled quick-dry brush cleaner, then deep-clean on schedule | Spot cleaning removes surface pigment but does not replace a full wash. |
| Someone else wants to use the brush | Do not share it | A clean disposable applicator or that person’s own brush is the simpler hygiene choice. |
| A brush was used around an irritated or infected eye | Stop using it and follow medical advice before reuse | Routine cosmetic cleaning is not a substitute for infection-control advice. |
What Cleaner Should You Use?
A dedicated brush cleanser is the clearest choice because its label tells you which brush materials it is intended for and whether it needs rinsing. A gentle clarifying shampoo is the straightforward alternative included in the dermatologist method above. Use only a small amount and rinse it out completely.
Avoid assuming that any product safe for hair, dishes, hands, or a countertop is automatically right for a makeup brush. Dish detergent can be unnecessarily aggressive for some fibers and finishes. Oils may loosen stubborn makeup but can also leave residue that changes how the brush picks up powder. Hand sanitizer and household disinfectants are not universal brush-cleaning products. Bleach and undiluted vinegar can damage materials or leave unwanted residue. If a brush manufacturer specifies a cleanser, that instruction takes priority.
Deep Cleaning vs. Spot Cleaning
Deep cleaning uses water and a rinse-out cleanser to remove product through the brush head. It is the regular maintenance method described above. Spot cleaning uses a purpose-made, quick-drying formula on the surface of the bristles, often so an eye brush can move from one color to another during the same makeup session.
Spot cleaning is useful, but it does not reach every part of a dense brush. Follow the product label, work in a ventilated area if directed, and wait until the brush is fully dry before putting it near the eyes or skin. Keep the normal deep-cleaning schedule even when you spot-clean between uses.
Drying Without Damaging the Brush
Drying is part of the cleaning job, not an afterthought. After blotting and reshaping, support the handle while the head hangs freely over a clean counter edge. Air can then reach all sides of the bristles, and moisture is less likely to travel into the ferrule.
Do not put a wet brush upright in a cup, close it in a makeup bag, or place it on a radiator. Avoid a hot hair dryer: heat can distort synthetic fibers and affect adhesives or finishes. If drying is routinely slow, improve room airflow and wash fewer dense brushes at once rather than adding heat.
Common Cleaning Problems
The rinse water stays tinted
Dense foundation and concealer brushes can trap product near the center. Add another small amount of cleanser, massage gently, and rinse again. Do not compensate by soaking the entire head or scraping it against a rough surface.
The brush feels stiff after drying
Stiffness often means product or cleanser remains in the bristles. Rinse the brush again with lukewarm water, squeeze it gently, reshape it, and let it dry flat. Adding oil or conditioner can introduce another residue and is not a reliable fix for every fiber type.
The brush smells musty
Do not use it while it smells unusual. Wash it again and let it dry completely in a clean, ventilated place. If the odor remains after a thorough wash and full dry, replacement is the safer practical choice.
The brush is shedding
One loose hair is different from repeated shedding. Persistent shedding, a moving ferrule, or a cracked handle indicates structural failure that cleaning will not reverse.
When to Replace a Makeup Brush
Makeup brushes do not have one universal replacement date. Condition matters more than age. Replace a brush when the ferrule is loose, the handle is cracked, bristles shed repeatedly, the head no longer returns to its shape, sharp or split fibers scratch the skin, or odor remains after correct washing and complete drying.
Permanent staining alone does not always mean a brush is dirty; some pigments tint light bristles even after the rinse water is clear. Judge the brush by residue, feel, smell, performance, and structural condition rather than color alone.
Brush Storage After Cleaning
Store only fully dry brushes. Keep them in a clean cup, roll, case, or divided drawer where the heads are not crushed. A closed travel case protects dry brushes in a bag, but it is a poor drying chamber. Clean the holder periodically too, otherwise a freshly washed brush returns to a dusty or product-coated surface.
Makeup sponges need their own care routine because their porous structure and replacement needs differ from brushes. Follow the sponge maker’s washing and replacement instructions rather than treating it as a brush.

Makeup brush cleaning FAQ
Can I soak makeup brushes in a bowl?
No. Wet and rinse the bristle tips while keeping the ferrule and handle out of the water. Soaking can move water into the parts that hold the brush together.
Can I use micellar water to clean brushes?
Use a product only if its maker labels it for brush cleaning and follow those directions. For a full routine, a rinse-out brush cleanser or gentle clarifying shampoo provides a clearer method.
Can I use the brush while it is damp?
Wait until it is fully dry. A damp brush can apply makeup unpredictably, and returning it to closed storage slows evaporation.
Should natural-hair and synthetic brushes be cleaned differently?
Both should be handled gently, kept out of prolonged soaking, rinsed thoroughly, reshaped, and dried flat. Because fiber treatments and adhesives vary, follow the maker’s instructions for the exact brush rather than applying a homemade treatment to all natural- or synthetic-fiber tools.
