## Features

- Hard water spots can destroy your vehicle’s finish, reduce efficiency with solar panels, and create a dirty appearance on windows. We know. That’s why we created a de-ionizing system that takes out all of the minerals in your water so you can just WASH, RINSE, and WALK AWAY!
- With a CR Spotless Water System with integrated bypass, you can let your vehicle, windows, and solar panels, air dry and not leave any spots behind. De-ionized water is the secret sauce that detailers, car washes, and solar / window cleaners have used for decades.
- CR Spotless was the first to make the same technology available to homeowners in an affordable, compact, and portable system. Work smarter, not harder and spend less time and money to get the same professional looking results.
- The DIW-20 provides approximately 300 gallons of mineral-free, de-ionized water based on your water input quality. It consists of two 20 inch de-ionization housings that feature replaceable (or refillable) cartridges that simply slide into the watertight tubes.
- With our integrated bypass your unit will provide more spotless water than ever before. Just turn the switch to bypass the filters during the wash process. When doing the final rinse turn on the filtration for spotless finish.
