## Description

Hard water spots can destroy your vehicle’s finish. 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, you can let your car air dry and not leave any spots behind. Besides cars, de-ionized water is perfect for washing and SPOT-FREE rinsing of your RV, boat, golf cart, motorcycle, and house windows, too! De-ionized water is the secret sauce that detailers, car washes, and 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 comes complete with 2 20 inch wall mounted cartridges containing a mixed bed of de-ionizing resin that will produce approximately 200 gallons of mineral-free water based on an average TDS level of 200 ppm. Depending on the quality of the water where you live, you can get between 75 and 1000 gallons of deionized water from one resin cartridge. All CR Spotless Water Systems also include a battery operated TDS meter that will measure the quality of the water coming out of the system. Includes two 20-inch wall mounted de-ionizing resin cartridges, Stainless Steel input Line, filter wrench, Spray nozzle, and battery operated water Purity Indicator - 1 Year
