Avoid letting paint dry in a brush. The paint will dry in the heel of the brush near the ferrule, making it difficult to be removed. This will cause the brush to lose its shape, brush hairs will fan out, and eventually, the brush will be unable to be used.
Do not use lacquer thinner, shellac remover or acetone to clean brushes. These solvents can dissolve the glues, which hold the brush hairs in place
