This Parts Cleaning system has a built-in electric pump that circulates solvant from the tank through a spout so that you can easily wipe/brush the grime and dirt off of anything you want to clean. It's very effective -- no professional shop would be without one, and if you like to work on your cars, you'd be lucky to have this in your garage! It also has a built in lamp that works. Comes with extra solvant. Pick up in Palo Alto
