The Detail Guardz Dirt Lock is a car wash bucket insert from 3D Products that traps dirt and debris underneath to keep wash water clean and efficient.
The design utilizes the motion of your hand to engage the Dirt Lock's turbine induction system. Once you pulse your hand in the bucket, the water is dramatically sped up by the shape of the jet turbine.
The dirt is then cycled through hundreds of tapered Venturi funnels and is further sped up again. This shoots the debris underneath the screen and out of harm’s way, without a way to re-enter the clean water.
In short, every time you pump your hand in the bucket you are cycling the dirt underneath the screen and replenishing it with reusable clean water.
