What Are Some of the Difficulties That Painters Face When They Use Brushes With Dried Paint on Them?

As mentioned previously, cleaning paint brushes are very important and there are several reasons behind it. There are many issues that you may face if the brushes are not cleaned properly. 

Leftover paint or build-up results in the hardening of the brush as they obstruct moisture retention. This is more common in natural brushes as they are delicate and their bristles are retained with organic oils. The paint or dust build-up in the bristles will dry the brush out.

In the case of synthetic brushes, the dry paint will affect the shape of the bristles and they may even start falling out if not washed regularly and properly. In both the above situations, losing the brush is an appropriate choice because a spoiled brush affects the painting. 

Apart from this, you also have to spend a lot of money every time you need to replace a damaged brush.

Some Proven Tips and Tricks for Paint Brush Care and Maintenance

Do Not Let the Paint Dry on Your Brushes 

As mentioned before, make sure to clean your brushes after every painting session and do not leave them on for days. Working with acrylic paints? Be extra careful because acrylic paints lose moisture pretty fast making them more difficult to clean.

Do Not Use Hot Water to Clean the Brushes 

Hot water can damage the bristles and expand the ferrule leading to falling out of the bristles. Always use warm water instead. 

Avoid Harsh Detergents, Paint Strippers, and Wire Paint Combs 

All of these are not recommended for cleaning the brush as these may damage the bristles. You need to handle your paintbrushes gently and with care.

Use Old Brushes for Dry Brushing Technique 

The dry brush technique is a common technique that is used by painters to add texture to the painting. It is used with dry thick paint and involves pressing the bristles against the canvas. This may lead to bending of the bristles that can ultimately damage the brush. So when you use this technique use an old brush. Do not rest your brush in the cup with bristle tip down while painting or even after you are done with painting. This would lead to bending of the bristles and will reduce the life of the brush.

Dry Your Brushes by Keeping the Bristle Tip Down 

After cleaning is done, remove as much moisture as possible. After that, either hang your brushes in a brush stand or just place them horizontally and let them dry. Drying the brushes with pointing the bristles upward will dampen and clog the ferrule with dust particles and the bristles may also get de-shaped. 

Use Water-mixable Paints

Water mixable oil paints are easier to clean when compared with complete oil-based paints. There may be a minor difference in the luster when compared with pure oil paints which an experienced artist figures out. When it comes to cleaning, do it by rinsing in mild soap and warm water.

Cleaning brushes with natural cleansers like oils will add life to your brush when compared with cleaning them with chemical-based solvents. 

Avoid Dipping the Brush Till Its Ferrule in the Paint Bottle

Make sure to dip only the bristle part of the brush in the paint and not up till the ferrule. This will not only save a whole lot of paint but also make cleaning easy. It will also protect the ferrule from getting deterioration by the washing process.
