Get Spot Free Car Washing with the Softener Deionizer! It will both soften and deionize the water to give you spot free results when washing or rinsing cars, RVs, boats, solar panels, windows, motorcycles, airplanes, trucks, boat isinglass, surgical instruments, etc. No more hand drying!
For completely spot free results, the water needs to be both softened to remove hard water minerals AND deionized to remove TDS (Total Dissolved Solids). Softened water will leave some spots but softened AND deionized water will leave no spots.
Note: Beware of claims that water softeners give spot free results. All water softeners that are regenerated using salt will remove calcium, magnesium and some iron but they won’t remove all of the “TDS” (Total Dissolved Solids) so they will leave some spots. In order to obtain spot free results, the water has to be both “softened” to remove hard water minerals and “deionized” to remove the “TDS”. This is done by using both softening and deionizing resin and the deionizing resin can’t be regenerated with salt water so it needs to be replaced. If you need spot free results, the Softener Deionizer will do the job!
