The best way to clean an acrylic brush is using a brush cleaner specifically made for it. There are some manufacturers who make really good ones, and that is what I use. Acrylic brushes are made of sable so you need to make sure you don’t contaminate the brush. Monomer can work well between services, but brush cleaner does the best job.
Some acetone has small traces of oil that can contaminate the brush. Also make sure to use only one brush for a product line; don’t use it for two different acrylic products. This goes for odorless as well. Pulling on the bristles will also damage the brush and the shape, so make sure you don’t pull them when cleaning. If there is already dried acrylic in the brush, it is best to purchase a new one.
