A reasonably priced deionized resin spot-free car rinse system with brass fittings! For best results and to conserve DI resin use with a hose end nozzle and adjust to a fine mist to rinse. When maintained properly, this unit will provide you with years of high-quality filtered water. Water quality is measured by the amount of total dissolved solids (TDS) in the water. It is the TDS in the water that leaves spots on a vehicle when the water evaporates. By removing the TDS, a spot-free rinse is created—making it much easier to achieve a nice dry surface. Removing TDS is accomplished by filtering the water through a resin that is charged with Cation and Anion resins (H+ and OH-). As the resin absorbs the TDS, it will change color. When the entire resin has changed color, it is time to replace the DI cartridge.
