How to Clean Hair Brushes with Baking Soda (the Easiest Way Ever)

I used to spend way too much time picking fuzz out of my hairbrush with a pair of tweezers. It felt like a chore that never really got the tool clean. Then I started using a simple pantry staple, and my brushes look brand new in under ten minutes. You do not need expensive sprays or fancy store tools to get the job done right. I promise you will never look back once you try this simple method.

You need one teaspoon of baking soda, a few drops of dish soap, and a bowl of warm water. Mix it well until the water gets bubbly. Submerge your plastic or rubber-based brushes for ten minutes. Rinse them well, let them air dry on a towel, and watch the built-up product residue vanish without any hard work.

Why Hair Brushes Need a Deep Clean

Most people forget about their brushes until they see a gray film or a clump of old hair. That buildup hides oils and dead skin, so it needs a wash.

Hair Product Buildup

Your hair products like spray or gel stick to the bristles every time you brush. This layer attracts dust and lint. Over time, that sticky surface makes your hair look greasy even after a wash. I noticed my hair stayed cleaner for two extra days after I started washing my brushes twice a month.

Natural Scalp Oils

The oil from your scalp travels down the bristles to your hair. While this is normal, the oil eventually turns rancid on the brush base. You are then putting old oil back into clean hair. A quick soak removes the grease that shampoo cannot reach. It makes a big difference for anyone with fine or flat hair.

Dead Skin Cells

Skin cells flake off constantly. They get trapped at the base of the bristles where it is hard to reach. This area becomes a home for bacteria if you ignore it too long. I once took a microscope to a dirty brush, and I wish I had not. It was enough to make me wash them every single week.

Dust and Lint

Static electricity pulls dust out of the air and into your brush. It mixes with the oils to form a thick, fuzzy mat. If you see this gray stuff, your brush is officially overdue for a bath. You might even be pulling that dust right back into your strands, which is not great for shine.

Bacteria Growth

Warm and damp bathrooms are the perfect spot for bacteria to grow. If your brush sits near the shower, it stays humid. This creates a breeding ground for germs right where you put them on your head. Regular cleaning stops this cycle. It is a simple step that keeps your scalp healthy and your hair feeling light.

Brush Longevity

Good brushes are not cheap. When grime builds up, it weakens the rubber base or damages the bristles. The acid in your hair products can actually eat away at the materials. I found that my favorite boar bristle brush lasted three years longer once I started a regular maintenance schedule. It is just basic care for your tools.

Actually, let me back up a second. Do not use this method on fancy wooden brushes, as the wood will soak up the water and warp. Stick to plastic or metal tools for this specific soak.

• Clear hair from bristles first.
• Use warm, not boiling water.
• Check the brush base material.
• Rinse thoroughly after the soak.
• Air dry with bristles down.
• Wash brushes twice monthly.

The Best Process to Clean Hair Brushes with Baking Soda

Cleaning your tools should not be a headache. This method takes very little effort and uses stuff you already have in your house, so you can do it right now.

Remove Loose Hair First

Before you start any liquid cleaning, get the hair out. If you leave the hair in, it acts like a sponge for the dirty water. That defeats the whole purpose of the soak. Use a comb to lift the hair out from the base.

It takes me about two minutes to clear a really full brush. If you do not have a comb, a clean pen or a spare toothbrush works just fine. Just get the bulk of the mess out so the water can hit the base directly.

Once the brush is clear of hair, you are ready to move on. Getting the physical hair out is the most important part of the process. If you skip this, the baking soda and soap mix cannot reach the skin cells stuck underneath the hair mat.

Mix the Cleaning Solution

Grab a bowl and fill it with warm water. You want it warm enough to cut through grease but not so hot that it melts the plastic. Add a teaspoon of baking soda to the water. It will fizz a little bit when it hits the water.

Next, add a small squirt of your favorite dish soap. The soap breaks down the oils, while the baking soda lifts the stubborn residue off the plastic. Stir it around with your hand until it is nice and bubbly.

Do not worry about exact measurements. A little more or less baking soda does not change much. I usually just shake some in until the water looks cloudy. This mixture is mild enough for your tools but strong enough to clean them well.

Soak the Brush Properly

Place your brush into the bowl with the bristles facing down. Make sure the entire head of the brush is underwater. If your brush is a cushion type, try not to submerge the air hole. Too much water inside the cushion makes it hard to dry.

Let it sit for about ten minutes. You can walk away and do something else while the solution does the work. I usually go start a load of laundry or just grab a quick glass of water.

When you come back, the water will probably look a little murky. That is actually a good sign. It means the soap and soda pulled the grime out of the bristles and off the base. You are seeing the clean happen right before your eyes.

Scrub the Tough Spots

If you see any bits left on the base, grab an old toothbrush. You can use it to scrub between the bristles. Since the soak already loosened the grime, it should come off with almost no effort. I focus on the area right at the base where the hair touches.

Sometimes, a tiny bit of lint stays stuck. A quick scrub with the toothbrush fixes that fast. You do not need to push hard. The baking soda acts like a gentle scrub that does not scratch the plastic or the rubber base.

Be careful not to pull on the bristles too hard. Just use light, circular motions to clear the gaps. It feels satisfying to watch the last of the gunk wash away. Your brush should look brand new once you finish this quick scrubbing step.

Rinse with Clean Water

Take the brush out of the soapy water and rinse it under the tap. Use cool or lukewarm water. Make sure you get all the soapy bubbles out from between the bristles. You do not want any residue left behind in your hair later.

I usually rinse for about thirty seconds. I tilt the brush in every direction to make sure the water flows through the base. If you have a cushion brush, give it a firm shake to get any trapped water out of the hole.

Check it one last time in the light. If it looks clean, you are done. If you see a spot you missed, just give it another quick scrub and rinse. It is a quick step that makes sure your hair stays clean and residue-free.

Dry the Brush Completely

The final step is to dry it the right way. Lay a clean towel on your counter. Place your brush with the bristles facing down on the towel. This lets the water drip out of the brush instead of pooling inside the cushion.

Leave it there for at least a few hours. I usually do this at night so the brush is dry by morning. If you try to use it while it is still damp, you might get a musty smell. That is never what you want in your hair.

Once it is totally dry, it is ready to use again. You will notice how much lighter it feels and how much better it moves through your hair. It is honestly one of the best habits to keep your tools in shape.

• Remove all hair first.
• Use only warm water.
• Avoid soaking wooden handles.
• Give it plenty of drying time.
• Keep the cushion hole clear.
• Clean once every two weeks.

Cleaning your hairbrushes feels like a small thing, but it changes how your hair looks. You are removing layers of old product and oil that weigh your hair down every single day. A fresh brush means fresh hair.

Does Baking Soda Damage Bristles?

Many people worry that using a cleaner will ruin their expensive brushes. I have used this on plastic and metal brushes for years without seeing any damage at all. Baking soda is a very mild abrasive, so it does not scratch the smooth surface of the plastic or the synthetic bristles.

I used to be scared to try this, but it is actually much gentler than the chemicals found in some store cleaners. Those harsh sprays can sometimes dry out the rubber, causing it to crack over time. Baking soda is a natural, safe way to lift the grime without causing any harm to the tool.

You just need to make sure you rinse it well. Leaving a white powder residue behind is the only real risk, and that happens if you rush the rinse. Take an extra ten seconds at the tap, and your brush will be perfectly clean and ready to go for the next use.

• Baking soda is mild.
• It won’t scratch plastic.
• Rinse well to prevent residue.
• Safer than harsh chemicals.
• Great for synthetic bristles.
• Keep away from wood.

Can I Use This on Wooden Brushes?

Actually, you should avoid soaking wooden brushes entirely. Wood is porous, which means it acts like a sponge. If you put a wooden hairbrush in a bowl of soapy water, it will absorb the liquid. This leads to the wood swelling up, cracking, or even developing mold inside the handle.

I learned this the hard way when I soaked a nice bamboo brush. The handle split right down the middle after it dried. Now, I only use a damp cloth with a tiny bit of soap to wipe down the wooden handle. I keep the water away from the base as much as I can.

If you have a wooden brush, just use the brush to flick the hair out. Then use a barely damp paper towel to wipe the bristles clean. It will not get as deep of a clean, but it will keep the wood safe from water damage.

• Avoid soaking wooden handles.
• Use a damp cloth instead.
• Water causes wood warping.
• Mold hides in wet wood.
• Keep the base dry.
• Bristles can be wiped.

How Often Should I Wash My Brushes?

I think washing your brush twice a month is a good goal for most people. If you use a lot of hair spray or dry shampoo, you might want to do it once a week. Those products create a sticky film that grabs onto dust faster than natural hair oils do.

It really depends on your hair type too. If you have very thick hair that needs a lot of styling products, your brush will get dirty faster. You will know it is time to clean when you see the gray fuzz start to build up at the base.

Do not wait until the brush is totally clogged. It is much easier to clean a brush that has a little bit of dust than one that has a thick mat of hair and grime. Consistency is the secret to keeping your hair tools in great shape.

• Aim for twice monthly.
• Weekly if using sprays.
• Watch for gray fuzz.
• Faster cleaning is easier.
• Adjust for styling products.
• Consistency prevents buildup.

Will This Remove Old Product Residue?

Yes, the baking soda and dish soap combo is a pro at breaking down product. Think about how dish soap cuts through grease on your dinner plates. It does the exact same thing to the oils and silicones left behind by your hair products.

I have seen it remove thick layers of hair spray that looked like they were part of the plastic. The baking soda acts as a gentle scrub to help lift those stubborn bits. It leaves the bristles smooth and shiny, just like they were the day you bought them.

It even helps with that weird, waxy feeling you get on some plastic bristles. Once you rinse that away, your brush will glide through your hair instead of pulling on it. It makes the whole brushing experience feel much better and way more gentle on your scalp.

• Soap cuts through grease.
• Soda lifts sticky residue.
• Removes waxy buildup fast.
• Bristles become smooth again.
• Prevents hair pulling.
• Works on stubborn sprays.

Final Thoughts

I hope you found this guide helpful and easy to follow. Cleaning your brushes is one of those small tasks that makes a big difference in your daily routine. Once you see how much grime comes off that brush, you will probably be hooked. It is a tiny bit of effort for a much better result. Give it a try this weekend, and your hair will definitely thank you for the extra care.
