How To Refresh Old Makeup Brushes Without Spending Much

Makeup brushes are essential tools in any beauty routine, but over time they accumulate product buildup, oils, and bacteria that dull their performance and appearance. Replacing them frequently can be costly, especially if you own high-quality sets. The good news? Most worn-looking brushes aren’t beyond saving. With the right care, even stiff, misshapen, or discolored brushes can be restored to near-original condition—without spending more than a few dollars. This guide reveals practical, budget-friendly methods to deep-clean, reshape, and sanitize your old brushes using common household ingredients and smart techniques.

Why Old Brushes Need Refreshing

Over weeks and months of use, makeup residue, facial oils, and environmental dust embed into brush bristles. This buildup leads to several issues: reduced blending ability, patchy application, bacterial growth, and irritation—especially for sensitive skin. Additionally, dried foundation or concealer at the base of bristles can cause shedding and permanent deformation of the ferrule (the metal part holding the bristles). Ignoring these signs doesn't just affect your makeup results; it can compromise skin health. Regular maintenance prevents long-term damage, but when brushes have already degraded, a thorough restoration process is necessary.

Tip: Clean your brushes every 1–2 weeks for daily-use tools and monthly for occasional ones to prevent irreversible buildup.

Essential Supplies You Likely Already Have

The best part about reviving old makeup brushes is that you probably don’t need to buy anything special. Most effective cleaning agents are already in your kitchen or bathroom cabinet. Here’s what works—and why:

• Dish soap – Cuts through oil and cosmetic residue effectively due to its degreasing properties.
• White vinegar – A natural disinfectant that kills bacteria and helps dissolve stubborn buildup.
• Coarse salt or baking soda – Acts as a gentle abrasive for scrubbing the brush base.
• Olive oil or coconut oil – Softens hardened product near the ferrule without damaging bristles.
• Hydrogen peroxide (3%) – Helps lift stains and sanitize deeply, ideal for light-colored brushes.
• A small bowl and paper towel – For soaking and drying.

These items cost little or nothing if already owned, making this one of the most economical beauty upkeep practices available.

Step-by-Step Guide to Deep-Cleaning Old Brushes

Restoring old brushes isn’t complicated, but it does require patience and attention to detail. Follow this methodical approach to achieve optimal results.

1. Pre-treat with oil: Dip the bristle tips into olive or coconut oil for 5–10 minutes. Focus on areas where product has hardened near the ferrule. This softens dried makeup so it rinses away easily.
2. Wash with dish soap: In a small bowl, mix warm water with a teaspoon of dish soap. Swirl the brush gently against the palm of your hand or a silicone cleansing mat to create friction. Avoid submerging the entire brush—water in the ferrule can loosen glue and cause shedding.
3. Soak in vinegar solution (optional): For heavily soiled or smelly brushes, prepare a mix of one part white vinegar and two parts lukewarm water. Soak bristles only for 15–20 minutes, then rinse thoroughly.
4. Rinse completely: Hold under lukewarm running water until no suds or color runs out. Squeeze gently from base to tip using your fingers to encourage water flow through bristles.
5. Tackle stains with hydrogen peroxide: If bristles remain discolored, soak only the tips in diluted hydrogen peroxide (equal parts water) for up to 30 minutes. Rinse well afterward.
6. Reshape and dry: Gently squeeze excess water, then reshape the bristle head with your fingers. Lay flat on a clean towel with the head hanging slightly off the edge to prevent water from seeping into the handle. Allow 6–12 hours to dry completely before reuse.

“Many people throw out brushes too soon. In my studio, we revive old tools weekly using basic soap and oil. It saves money and reduces waste.” — Lena Patel, Professional Makeup Artist & Beauty Educator

Do’s and Don’ts When Cleaning Makeup Brushes

To avoid damaging your brushes during the refresh process, follow these guidelines carefully.

Do	Don’t
Use lukewarm water—never hot, which can warp bristles and weaken glue.	Submerge the entire brush; water in the ferrule causes shedding.
Clean synthetic brushes more frequently—they trap liquids and bacteria faster.	Use strong alcohol-based cleaners unless absolutely necessary; they dry out bristles.
Lay brushes flat to dry to maintain shape and prevent moisture damage.	Stand brushes upright in a cup while wet—this allows water to pool in the base.
Condition natural hair brushes occasionally with a drop of argan or jojoba oil.	Scrub aggressively on hard surfaces, which frays delicate bristles.
Use a cleansing mat or textured silicone pad for better deep-cleaning action.	Leave brushes damp overnight—mold and mildew can develop inside the handle.

Bonus Techniques for Stubborn Buildup

Sometimes, standard washing isn’t enough—especially for stippling brushes used with thick foundations or densely packed eyeshadow blenders. For extreme cases, try these advanced yet affordable tricks:

• The Shampoo + Conditioner Method: Use baby shampoo (gentle pH) followed by a tiny amount of conditioner on natural-hair brushes to restore softness after deep cleaning.
• Baking Soda Paste Scrub: Mix baking soda with a few drops of water to form a paste. Gently rub it around the base of the bristles where gunk collects. Rinse immediately after.
• Vinegar Steam Loosening: Hold the brush over a steaming kettle (not touching the water) for 10–15 seconds to loosen caked-on product, then wash as usual.
• Freezing Trick: Place a badly clogged brush in a sealed bag and freeze overnight. The expansion of trapped moisture can help break apart dried product, making it easier to clean the next day.

Tip: After cleaning, store brushes in a breathable container—like a fabric roll or open-air holder—to prevent mustiness.

Real Example: Reviving a $40 Brush Set for Under $3

Sarah, a freelance makeup artist in Portland, inherited a professional brush set from her mentor. Though high-end, the brushes were neglected—bristles were stiff, stained brown from old bronzer, and some had bent ferrules. Instead of replacing them, she spent one evening restoring them using only Dawn dish soap, white vinegar, coconut oil, and a repurposed silicone phone case as a scrubbing surface.

She pre-soaked each brush in oil, washed with soapy water using circular motions on the textured silicone, soaked stained brushes in vinegar-water, and rinsed thoroughly. After reshaping and air-drying overnight, all eight brushes performed like new. “I saved over $40,” she said. “They blend better now than when I first got them. Plus, I feel good knowing I didn’t contribute to beauty waste.”

This example shows that investment isn’t always monetary—it’s in effort and consistency.

How Often Should You Refresh Your Brushes?

While full restoration may only be needed every few months, regular upkeep extends the interval between deep cleans. Here’s a simple maintenance timeline:

• Daily: Wipe off excess product with a microfiber cloth after use.
• Weekly: Quick cleanse with soap and water for frequently used brushes (foundation, concealer).
• Monthly: Deep clean all brushes, including eye and powder tools.
• Every 3–6 Months: Full restoration using oil, vinegar, and stain treatment as needed.
• Annually: Inspect for irreversible damage—excessive shedding, loose ferrules, mold. Retire unsafe brushes.

Sticking to this rhythm keeps brushes functional and hygienic far longer than sporadic cleaning.

FAQ

Can I use hand soap instead of dish soap?

Hand soap is less effective because it’s formulated to moisturize, not cut grease. Dish soap is specifically designed to remove oils and residues, making it superior for brush cleaning. Stick with clear, fragrance-free dish liquid for best results.

Is it safe to use vinegar on natural hair brushes?

Yes, but dilute it properly (1 part vinegar to 2 parts water) and limit soak time to 15–20 minutes. Always follow with a thorough rinse and conditioning step to prevent dryness. Natural bristles respond well to occasional vinegar treatments for odor and germ removal.

My brush still smells after cleaning. What should I do?

Odors usually mean trapped bacteria or mold. Repeat the vinegar soak (15 min), then rinse and let dry in indirect sunlight for a few hours—UV rays naturally disinfect. Never store a brush that still smells; it can transfer bacteria to your skin.
