Why Does My Makeup Brush Smell after Washing? (How to Fix)

My Makeup Brush Smell after Washing:

Do your makeup brushes have a strange smell even after you wash them? This is a common and frustrating problem.

You wash your brushes to keep them clean and germ-free, so it is annoying when they come out smelling bad.

This blog post will explain why this happens and give you clear steps to fix it. First, let’s look at the reasons your brush might smell after washing.

Reasons Why Do My Makeup Brushes Smell After Washing

There are several reasons your clean brush might still have an odor. Understanding the cause is the first step to fixing it.

1. It took too long to wash the brush

Makeup brushes collect a buildup of makeup, oil, sweat, and bacteria every time you use them. A dirty brush is full of germs that cause bad smells.

If you do not wash your brushes regularly, this dirt and bacteria build up deeply. When you finally wash them, the bacteria may not wash out completely and can start to stink.

2. Not washing the makeup brush thoroughly

If you do not wash the brush well enough, old makeup and bacteria can be left behind. Also, if you do not rinse out all the soap, soap residue stays on the bristles.

This leftover soap can make your brush start to smell funny over time.

3. Using the wrong makeup brush cleaning product

Using the wrong cleaner can cause problems. You need a product made for delicate makeup brushes.

Strong soaps or detergents can leave a residue that makes brushes smelly. Also, a cleaner meant for hair can damage your brush’s bristles.

4. Using substandard makeup brushes

Cheap brushes are often made with poor-quality materials. These materials can cause a bad smell.

The bristles might be a mix of synthetic and natural hairs. Natural hairs are sometimes treated with chemicals that smell when washed.

Also, the plastic handle of a cheap brush can absorb water and develop a mildew smell.

5. The makeup brush is old

If you have had your brushes for a long time, they are more likely to smell. Older brushes have had more time to accumulate bacteria deep inside.

This bacteria buildup can become impossible to wash out completely. Also, bristles wear out over many washes and may hold onto odors.

6. Not setting brushes out to dry correctly

Drying your brushes the wrong way is a major cause of smell. If brushes stay damp, they can develop a mildew odor.

Without proper airflow, bacteria and mold continue to grow in the moist bristles. This causes a funky smell to come from your brushes.

How Do You Get the Smell Out of Makeup Brushes

Here are practical steps to eliminate odors and keep your brushes fresh after every wash.

1. Wash the makeup brush regularly

Wash your brushes often to prevent heavy buildup. If you cannot wash them right after use, blot them on a tissue first.

Store them upright in a dry place. Even brushes you haven’t used in weeks can collect dust, so give them a quick wash before using them again.

For long-term storage, keep brushes in a drawer to protect them.

2. Use the right cleaning product

Use a cleaner made specifically for makeup brushes. This will properly remove oils and product residue.

Avoid very strong soaps or scented cleaners, as the fragrance and residue can cause smells. For brushes with natural bristles, use a little conditioner to keep them hydrated.

A brush cleaning tool can help clean thoroughly without damage.

3. Dry the makeup brush the right way

Proper drying is crucial. After washing, gently squeeze excess water from the bristles with a towel. Do not wring or twist them.

Never stand wet brushes upright. Water can run into the handle, causing mold and damaging the glue.

Lay them flat on a towel or, even better, hang them upside down so water drips away from the handle. This keeps their shape and prevents mildew.

4. Buy good quality makeup brushes

Invest in better quality brushes. They are made with higher-grade materials that are less likely to hold odors.

Good brushes last longer and maintain their shape. They are a worthwhile investment to avoid the smell problems of cheap brushes.

5. Change your makeup brush regularly

Replace your brushes every few months, especially if you use them daily. Over time, brushes become less effective and can harbor odors that won’t wash out.

Synthetic brushes, in particular, wear out and may need replacing more often to stay fresh.

6. Keep your brush holders clean

Your brush holder or cup can also be a source of bacteria. If it is dirty, it can transfer germs to your clean brushes.

Clean your brush holder regularly with warm, soapy water. Rinse it well and dry it completely before putting brushes back in.

A moist holder will encourage bacteria growth.

7. Use vinegar

If soap washing does not remove the smell, try white vinegar. Vinegar kills bacteria and eliminates odors.

Mix one part vinegar with three parts warm water in a bowl. Soak each brush in the solution for 10-15 minutes.

Then, rinse the brushes very well under lukewarm water until no residue remains. Lay them flat to dry completely before using them again.

Conclusion

A smelly makeup brush after washing is annoying, but it can usually be fixed. The causes are often leftover makeup, bacteria, or improper drying.

You can keep your brushes fresh by washing them thoroughly, using the right cleaners, and drying them correctly. Taking good care of your brushes makes them last longer and protects your skin from irritation.

Next time you clean your brushes, remember these simple tips to prevent bad smells.
