With all the comments from the last post explaining excellent ways to care for brushes that would work for most people, I suppose I should explain about my brushes some more.
My brushes are worn out, not neglected. At the end of their lives they are dull and becoming ragged. Almost never do I have a brush ruined because it has dried in paint in it. I have only about four. A #1, a #4, a#12 and a rigger which lasts a long time as I do maintain those carefully and use them very little. You have seen painters with great handfuls of brushes and they keep a separate one for every color. I clean mine in between colors on a paper towel and that wears them. I also scrub, jab and mash them into the paint.
Rinsing them out in thinner works for me because I paint every day, they really don't have time to dry out. I could probably stretch their lives a little, but I don't have the patience to wash them. When I teach workshops virtually every students brushes are ruined. I like em new and sharp.
If you are gently stroking with your brushes I suppose they will last longer and if you have many you will spread the wear over the entire assemblage. If you paint every day using two or three you go through them.
I was taught in the Gammell studios how to rub the brush in bar soap and clean it on my palm. I used to spend perhaps 15 minutes every night cleaning brushes, but over the years I have abandoned that. I think the Masters brush cleaner is a good product if you want to clean them incidentally. But as I said I beat them and wear them out, so cleaned or not they rapidly become dull. I am the same way with shoes incidentally.
