Spot Free Car Wash System 50 | Deionized Water DI Rinse

The 50 is our compact/shorter model. Great for mobile setups, detailing carts or mounting on a shelf.

Available with 2 different inlet/outlet styles:

Our Standard system features a standard male garden hose inlet and outlet size for constant water treatment

We suggest picking up one of our female adapters to easily use 2 standard garden hoses: 3/4" Garden Hose Female to Female Twist Adapter | GHT

Our Bypass system allows you to easily turn the water treatment on and off. Simply turn both red dials inward to bypass the resin treatment.

Our ultrapure deionization tanks remove all spot causing minerals from the water fed to the tank. The water produced is an excellent use for a spot-free car and RV wash, window cleaning, and much more!
