What's the worst part about washing your vehicle?


Using your standard water supply, the Double Chuck produces spotless water that makes it possible to Just Wash, Rinse, and Walk Away!® We guarantee you'll have 100% spot free paint, glass, and chrome with absolutely no need for towel drying.


Tap Water

The unfiltered tap water supply to your home's outside faucet and sprinklers are full of salts, minerals, and calciums. When left to dry in the sun, these natural elements  leave behind unsightly water spots on your paint finish. Over time, they become painfully difficult to remove.

Spotless Water

The Double Chuck removes 100% of the salts, minerals, and calciums from your tap water supply through a process called deionization.  The result is pure H2O containing zero elements that can create water spots.  100% spot free washing even with no towel drying even in the heat of the sun!
