I used to use that, but was told it would eventually dry your brushes out so I stopped. I wonder though, if the problem would be true with synthetic brushes. I’ll have to see if I can find anything on the subject.
I switched to a taller jar of water and that seems to have done the job. I think my smaller jars just weren’t long enough to give the bristles a chance to open up. This is the largest round I’ve ever had. My 1-inch flats probably have as much bristle but of course they are laid out differently. This brush is just so thick in the middle.
