You know how frustrating it feels when you grab your paint brush, only to find it hard and crusty with dried paint? You want to paint again, but the brush just won't work right. The good news is you can fix this! You don't have to throw your brushes away. In this article, you will learn simple, easy ways to clean paint brushes with dried paint. No matter if the paint is old or really stuck, these methods will help you save your brushes and make them ready to use again.
Soften the Dried Paint with Warm Soapy Water
When paint dries on brushes, it gets hard and stiff. The first thing you need to do is make that dried paint soft again. Warm soapy water works great for this. You just fill a container with warm water and add some dish soap. Then, soak your paint brush in the water for a few hours or even overnight. The warm water and soap will help the paint to loosen up from the bristles.
Be sure the water is not too hot because it might damage your brush hairs. Check your brush now and then by gently trying to rub the paint with your fingers. After soaking, try using your fingers or a soft brush comb to remove the softened paint. You might need to repeat soaking if the paint is very thick or stubborn.
If the paint is water-based like acrylic or latex, this method works very well. For oil-based paints, the warm soapy water may only help a little, but it is still a good first step. Be patient and gentle so you don't break your brush.
- Fill a container with warm water and dish soap
- Soak the brush for several hours or overnight
- Use fingers or a soft comb to remove softened paint
- Repeat soaking if needed
- Avoid very hot water to protect brush hairs
Use Vinegar to Break Down Tough Paint
If soaking in soapy water is not enough, vinegar can help. Vinegar is a natural acid that can soften dried paint very well. To use vinegar, pour some into a small pot and heat it on the stove until it's hot but not boiling. Then, carefully dip your brush into the hot vinegar and let it sit for about 15 to 30 minutes.
The vinegar will break down the dried paint, making it easier to clean. After soaking, use a brush comb or your fingers to pull the paint off. You can repeat this step if the paint is still stuck.
Be careful with vinegar because it smells strong, so use it in a well-ventilated area. Also, avoid using vinegar on very delicate brushes or those with wooden handles that can get damaged by heat.
- Heat vinegar until hot but not boiling
- Soak brush in hot vinegar for 15 to 30 minutes
- Remove softened paint with fingers or brush comb
- Repeat if necessary for stubborn paint
- Use in a ventilated area to avoid strong smell
Apply Paint Thinner or Mineral Spirits for Oil-Based Paint
When your brush has dried oil paint or enamel paint, regular water or vinegar might not work well. For these types of paint, paint thinner or mineral spirits are your best friends. These liquids dissolve oil paint and make it easier to clean.
Pour a small amount of paint thinner into a jar or container. Dip your brush into it and let it soak for about 30 minutes. After soaking, swirl the brush inside the thinner to loosen the paint. Then, use a brush comb or a cloth to wipe away the paint.
Make sure to work in a well-ventilated place because paint thinner has a strong smell and can be harmful if you breathe it in too much. Wear gloves to protect your hands and avoid skin contact.
After cleaning, wash the brush with warm soapy water to remove any leftover thinner. This keeps your brush soft and clean.
- Use paint thinner or mineral spirits for oil-based paint
- Soak brush in thinner for about 30 minutes
- Swirl brush in thinner and wipe off paint
- Work in a ventilated area and wear gloves
- Wash brush with warm soapy water after cleaning
Use Baking Soda Paste for Extra Cleaning Power
If the paint is still not coming off easily, baking soda can help. Baking soda is a gentle but effective cleaner. Make a thick paste by mixing baking soda with a little water. Then, apply this paste directly to the dried paint on your brush.
Use your fingers or an old toothbrush to scrub the paste into the paint. The baking soda will help break the paint apart and lift it from the bristles. After scrubbing, rinse the brush under warm water.
You can repeat this process a few times until most of the dried paint is gone. Baking soda is safe to use and does not damage your brush. It works well especially after using vinegar or thinner.
- Make a paste with baking soda and water
- Apply paste to dried paint on brush
- Scrub gently with fingers or toothbrush
- Rinse with warm water
- Repeat if needed for stubborn paint
Comb the Brush to Remove Leftover Paint
After softening and cleaning, some paint may still hide deep inside the brush. Using a brush comb or an old fine-tooth comb can help remove these pieces.
Hold your brush firmly and gently comb through the bristles from the base to the tip. This pulls out paint flakes and cleans between the hairs. Be gentle so you don't pull the bristles out or damage the brush shape.
For very tough spots, you can dip the comb in soapy water or paint thinner before combing. This will help loosen paint stuck between the bristles. After combing, rinse your brush again with warm water.
- Use a brush comb or fine-tooth comb on bristles
- Comb from base to tip gently
- Dip comb in soapy water or thinner for tough paint
- Rinse brush after combing
- Be gentle to protect brush shape
Rinse and Condition the Brush
Once you have removed most of the dried paint, it is important to clean the brush fully and keep it soft. Rinse your brush well under warm running water until no soap or paint residue remains.
After rinsing, use a little hair conditioner or brush cleaner to soften the bristles. Work the conditioner gently into the hairs, then rinse again. This step helps keep the brush soft and ready for the next use.
Dry your brush by shaping the bristles back into place and laying it flat or hanging it with the bristles down. Avoid standing it up with the bristles up because water can get trapped and ruin the brush.
- Rinse brush under warm water thoroughly
- Apply conditioner or brush cleaner for softness
- Rinse again to remove conditioner
- Shape bristles and dry flat or hanging with bristles down
- Avoid storing brush standing bristles up
Prevent Dried Paint by Cleaning Brushes Right After Use
The best way to save time and keep your brushes perfect is to clean them right after you finish painting. Don't let paint dry on your brush. For water-based paints, rinse the brush under warm water and use soap to clean it fully. For oil-based paints, use paint thinner or mineral spirits right away before the paint dries.
Wipe off extra paint with a cloth or paper towel before cleaning. Store brushes properly by wrapping the bristles or putting them in a brush holder. Regular cleaning and proper storage will keep your brushes soft and long-lasting.
- Clean brushes immediately after painting
- Rinse water-based paint with warm water and soap
- Use thinner for oil-based paint right after use
- Wipe off extra paint before cleaning
- Store brushes properly to keep shape and softness

Frequently Asked Questions (FAQs)
Is it possible to fully restore a brush with dried paint?
Yes, it is often possible to restore brushes with dried paint, but the success depends on how long the paint has been dry and what type of paint it is. For water-based paints, brushes can be restored even after days or weeks by soaking and softening the paint. Oil-based paints are harder but can still be cleaned with paint thinner or mineral spirits. If the paint has been dry for many months or years, some brushes may lose bristles or stiffness, making full restoration difficult. But trying the cleaning steps usually improves the brush a lot.
Can I use household items instead of special brush cleaners?
Yes, household items like vinegar, baking soda, warm soapy water, and even cooking oil can help clean brushes. Vinegar softens dried paint, baking soda scrubs gently, and warm water loosens paint. Cooking oil can sometimes soften oil paint on brushes. While special brush cleaners work faster and better for tough paint, household items are good alternatives for easy and cheap cleaning. Just be patient and repeat cleaning steps if needed.
Do I need to wear gloves when using paint thinner?
It is highly recommended to wear gloves when using paint thinner or mineral spirits. These chemicals can irritate your skin and cause dryness or allergic reactions. Gloves protect your hands from contact with harmful substances. Also, work in a well-ventilated area to avoid breathing in strong fumes. Safety is important when using any chemical cleaners.
Is it okay to soak brushes overnight in paint thinner?
Soaking brushes overnight in paint thinner is usually okay for very stubborn paint, but it can damage some brushes, especially those with natural hair or glued parts. Prolonged soaking might weaken the glue and loosen bristles. It's better to check your brush after a few hours and remove the paint as soon as it softens. For regular cleaning, shorter soaking times are safer.
Can dried paint be removed without damaging the brush?
Yes, dried paint can be removed without damaging the brush if you are gentle and patient. Using warm water, vinegar, baking soda, and paint thinner carefully helps loosen paint without pulling or breaking bristles. Avoid harsh scraping or using wire brushes. Comb the brush softly and condition it afterward to keep it soft and strong.
Do I have to clean my brushes immediately after painting?
Yes, cleaning your brushes immediately after painting is the best way to avoid dried paint problems. Fresh paint is much easier to clean. For water-based paints, rinse with warm water and soap right after use. For oil paints, clean with paint thinner soon after finishing. This saves time and keeps your brushes soft and ready for the next project.
Is vinegar safe to use on all paint brushes?
Vinegar is generally safe for synthetic brushes and those with metal or plastic handles. However, it can damage wooden handles or very delicate brushes if soaked too long or if the vinegar is too hot. Always use vinegar carefully and rinse brushes well afterward. Test on a small part of the brush if you are unsure.
Can I use baking soda to clean all kinds of dried paint?
Baking soda works best on water-based paints and can help break down dried paint gently. It is not very effective on thick, dried oil paints by itself but can be used together with other methods like vinegar or paint thinner. Baking soda is safe and non-toxic, making it a good choice for regular cleaning and gentle scrubbing.
