Better than my liquid soap
I had a liquid soap that I'd been using for some time. I was able to get paint off the ferrule but eventually my brushes would get clogged with paint and be relegated to the scrap bin. Fortunately, I rarely throw a brush away, preferring to use it for everything that's hard on a brush. I had a size 1 Reaper brush that I got a ton of paint out of the first time I used this product. The brush went from being kind of crappy to totally usable again and I'm super pleased. I was able to rescue a number of Kolinsky brushes that I had sort of given up on so my small investment paid big dividends.
