Deionized water for spotless rinse use is produced by running water over an ion-exchange resin. This process exchanges calcium and magnesium ions for sodium ions. Two types of anion resin are generally used for deionization: weak base and strong base resin. Weak base resin absorbs strong acids and strong base resin exchanges chloride, sulfite, and alkaline anions for hydroxide ions. Low levels of sodium salts remain in deionized water and can form some spots, but they usually wash off very easily with minimal scrubbing. A variety of industries utilize spotless rinse water for services, such as:
Spotless Rinse
- Window Washing
- Automobiles
- Car Washes
- Detailing Services
- Solar Panel Cleaning
- Outdoor Furniture
- Boats
- Recreational Vehicles
- Motorcycles
- ATVs
Ion-exchange resin works by taking advantage of the difference in bonding strength to sulfonates between sodium ions and calcium or magnesium ions. As water passes through the filters, the spot causing calcium and minerals cling to the resin beads, thus creating deionized water. Over time, the resin will weaken and need to be regenerated to continue performing efficiently.
