Works. Jar of solid brush soap.
You get a jar of solid soap for use on painting brushes. They suggest using this for oil, watercolor, and acrylic paintbrushes that need cleaning. You unscrew the top and rub the wet, dirty brush against the soap to work the soap into the brush. Obviously, you then rinse the brushes. It seems to work fine and seems comparable to the brush soap that I currently use. I allow the soap to dry out before screwing the cap back on.
