Pro Products Rust Out Water Softener Cleaner in water softeners eliminates resin bed fouling and prolongs your water system unit's life. Changes rust and iron into a clear solution that easily rinses away, and does not contain harsh or abrasive chemicals that can damage fiberglass, porcelain or acrylic surfaces.

Follow the instructions on the resin bed cleaner bottle:  Dissolve 1 cup of solution in a 1/2 gallon of cold water. Pour resin bed cleaner directly into brine well, or for softeners with no brine well, pour directly into salt tank when salt level is at it's lowest. Set the softener to regenerate. If your softener is heavily fouled, repeat the same steps for the system.
