Pro Res Care will chemically clean a fouled resin bed of a water softener and restore the exchange capacity of the resin. Most types of water softening resins can become fouled with iron and other contaminants that will affect the performance of the ion exchange system. Iron fouling can cause channeling, pressure drop, loss of capacity, hardness and iron leakage. Regular use of Pro Res Care will minimize fouling and extend the resin life in the water softener. Use 2-3 ounces with each water softener regeneration.
