The Dirt Lock
wash bucket insert is an amazing design. It utilizes the motion of your hand to pump and trap debris underneath the screen. The Dirt Lock has a complex Venturi filtering system that manipulates the flow of water in a downward direction. This allows dirt particles to collect underneath the screen (at the bottom of your bucket) without letting the dirt and grime re-circulate into the cleaner water. In short, every time you pump your hand in the bucket, you are cycling the dirt underneath the screen and replenishing clean water above to help prevent swirl marks and scratches on the painted surface.

Scrub Wall 180 and 360 System Attachment can be used with the Dirt Lock.
