What is a water softener resin cleaner?

Water softener resin cleaner is a chemical formula – in liquid and powder form- to remove the more stubborn substances trapped in the resin beads while softening hard water. A water softener resin rescuemaintains and rescues the efficiency of the softener resin.

The softener resin attracts calcium, manganese, and iron to discharge soft water. By doing so, it accumulates layers of the said minerals in the resin beads where the water softening occurs most.

If it is let go unchecked, the resin looses the efficiency of exchanging ions to replace mineral or organic substances from the water. This is when and why you need a resin cleaner to regain and increase the effectiveness of the resin. Therefore, a resin cleaner is called sometimes a resin rescue orwater softener resin restorer. A timely application of resin cleaner will certainly extend the resin life.

Things to Know before Buying water softener resin cleaner

How to clean water softener resin with the best water softener resin cleaner?

To rescue or restore the softener resin that is fouling or fouled to the grievous level, you need to go through the following steps.

  • Feed the resin cleaner into the salt tank or pour suggested amount of the resin cleaning formula into the brine tank.
