Unger Rinse 'n' Go Replacement Filter for Spotless Car Washing, Spotless and Streak-Free Results, Replacement Filter, Great for RVs, Motorcycles,

The Rinse N Go Water Softener System is a product that comes in a plastic bucket with two quick-connect garden hose fittings. The system is designed to use a replaceable "filter bag" to remove dissolved minerals from the water and provide soft water for washing cars, boats, and motorhomes. Overall, the product works as advertised when the resin bag is still functional. However, the cost of replacing the filters often for the amount of water received from the system is a setback for some customers. Some customer believes that the filters are expensive, and it takes almost two filters to wash a motorhome. One of the reviewers would rather spend money having the motorhome washed than spend time and money on the filters. Though the resin bag can last for more than ten uses with soft water, it can deteriorate before eleven car washes. The replacement of the resin bag is easy to do. The results were the same with the new resin, spotless. But you may want to use your feet on the Rinse N Go base to help remove the top. It looks like the filter's longevity is reduced depending on how hard the water is.
