See the post above - spin the water or solvent out of a paint brush after washing it. Get a nice paintbrush out and put it between the jaws, pull the ring to tighten and done. Remember, paint used to be all oil based and good brushes weren't thrown out. The spinner gets the solvent out, and doesn't involve the spinning between your hands, allowing you to use a can to spin the brush to recover the solvent and keep the mess down.
