How to Clean Your Makeup Brushes and Cosmetic Sponges: Step-by-Step

Quick Answer

To clean makeup brushes and sponges, wet the bristles or sponge, apply a gentle cleanser or brush cleaner, work into a lather, rinse thoroughly, and let them dry completely. Wash brushes weekly and sponges every few days to prevent bacteria buildup and breakouts.

Dirty makeup brushes and cosmetic sponges harbor oil, dead skin, and bacteria that can lead to clogged pores and breakouts. Regular cleaning keeps your tools in good condition and your skin happy. Here's a practical step-by-step approach to washing them effectively.

You don't need fancy equipment—just a gentle cleanser, lukewarm water, and a bit of time. Below, we break down the process for both brushes and sponges, along with common mistakes to avoid and how often to clean them.

What You Need to Clean Makeup Brushes and Sponges

Start with a gentle cleansing product. A dedicated makeup brush cleaner works well, but a mild baby shampoo or fragrance-free liquid soap is also effective. For sponges, use a cleanser that can break down silicone-based makeup, such as a gentle dish soap or solid cleanser.

You'll also need a small bowl or your sink, lukewarm water (hot water can damage glue and bristles), and a clean towel or paper towel for drying. Avoid soaking brushes handle-first, as water can loosen the glue over time.

• Use lukewarm water, never hot.
• Avoid soaking the ferrule (metal part) of brushes.
• Use a separate clean towel for drying.

Step-by-Step: How to Clean Makeup Brushes

Wet the bristles of a brush with lukewarm water, keeping the ferrule dry. Apply a small amount of cleanser to your palm or a cleaning mat, then swirl the brush in the product until it lathers. Work the lather through the bristles to lift makeup and oils.

Rinse the brush under running lukewarm water, bristles pointed downward, until the water runs clear. Squeeze the bristles gently with your fingers to remove excess water, then reshape them. Lay the brush flat on a towel to dry, with the bristles hanging slightly off the edge of a counter so air circulates.

• Checkpoint: If the water still shows makeup residue, repeat the lathering and rinsing.
• Common mistake: Drying brushes upright in a cup—water seeps into the ferrule and weakens the glue.

Step-by-Step: How to Wash Cosmetic Sponges (e.g., Beauty Blender)

Wet the sponge thoroughly with lukewarm water. Apply a gentle liquid soap or a dedicated sponge cleanser directly to the sponge. Squeeze and massage the sponge under running water, repeatedly squeezing to release makeup and buildup. Continue until the water runs clear and the sponge returns to its original color.

Rinse thoroughly, then squeeze out as much water as possible. Let the sponge air-dry on a clean towel or a drying rack. Never wring it out, as that can tear the sponge. Make sure it's fully dry before storing to prevent mold.

• Checkpoint: The sponge should return to its original color when clean.
• Common mistake: Microwaving sponges to 'sanitize'—this can melt or damage the material.

How Often to Clean Brushes and Sponges

As a general rule, clean makeup brushes once a week to prevent bacteria from accumulating. Sponges used for liquid foundation should be washed every three to four days since they absorb more product and moisture, making them a breeding ground for bacteria.

If you use a sponge daily, consider buying multiple and rotating them so each has time to dry completely between uses. Brushes used for eye makeup (especially cream formulas) may need cleaning more frequently to avoid irritation.

• Set a weekly reminder for brush cleaning.
• For sponges, clean after every three to four uses.
• When in doubt, smell the tool—a musty odor means bacteria have taken hold.

Quick Cleaning Routine: Steps to Remember

1. Gather supplies: Lukewarm water, gentle brush cleaner or mild soap, clean towel. Avoid harsh detergents that can strip brush bristles.
2. Wet the tool: For brushes, wet only the bristles; for sponges, wet fully and squeeze out excess water. Never submerge the brush handle or ferrule.
3. Clean and lather: Swirl brushes in cleaner; massage sponges with soap until they return to their original color. Rinse until water runs clear.
4. Dry flat: Lay brushes flat with bristles over a towel edge; let sponges air-dry on a clean surface. Full drying prevents mold and bacteria regrowth.
