I swirl small batches around in a plastic coffee container with warm water and dish soap and rinse them with clean water in a strainer. Then i do it all over again. Then i dry them in a clean soft cloth very gently. Then air dry. After they are really dry i spray a small amount of pledge in a empty tin and swirl about 20 at a time until they are covered. Then i dry them with a hair dryer. Works great. Very accurate. They stay clean looking longer and my fingers are much cleaner after shooting. So is my barrel. I wouldnt want acetone in my gun.
