How to Clean Polyurethane Brushes with Paint Thinner?
Polyurethane brushes are the most well-known and effective tools for artists. But the first time you use them, they don’t do what you want them to do. Before you clean your brush, make sure it’s in good condition. But cleaning a brush isn’t easy. It can’t be cleaned with standard cleaners like your brush cleaner. To properly clean your polyurethane brushes, follow these steps.
Get your polyurethane brushes filled with water. Then, rub them with a towel for five minutes. This process will protect the hair from damage.
Rub the brush over the hair to get rid of the hair. The hair can be removed with tweezers or scissors. The best tool for this job is tweezers.
Clean the brush by spraying it with paint thinner. Paint thinner will work just like any brush cleaner you already have. You can use it without worrying about damaging your skin. To thin the paint, add the same amount of water. Then, add shampoo to the mixture and clean your brush with it.
After cleaning, soak the brush in water for 10 to 15 minutes. Use soap to clean the brush and then dry it with a fan. This step will help remove dirt on the brush.
How do I clean oil-based polyurethane from a brush?
It is possible to remove polyurethane using paint thinner or white spirit. If the brush has been dry for a long time, soak it in water. When you rub the polyurethane on the brush, it will soften. Clean paint brushes should be cleaned with acetone. Wash the brush with soapy water to remove the acetone.
But this soap smooths the bristles, so you can use it again without any hassle. This process is difficult to understand and takes a lot of time, but it is worth it if the brush is good.
Cleaning brushes using a brush comb
A brush comb is the best and easiest way to clean your brushes. With this tool, it is easy to clean paint from brushes. There are various brush combs available in the market. Choose the one that works best for you.
Slowly insert the comb into the brush, and then shake it well. Do this repeatedly until there is no dust left.
Dry the brush with a clean cloth. When you put the brush upside down in an open jar, make sure that the bristles are facing upwards. This way, the brushes dry quickly and do not have a chance to grow mold and mildew.
