A water softener is an important home appliance that removes minerals e.g. iron, magnesium or calcium from hard water that could otherwise stain and clog your pipes. A water softener has resin beads that absorb the undesired minerals and replaces them with sodium, before the water reaches your kitchen or bathroom taps. The system keeps fresh water running to your home all through, but the buildup of these minerals in the system would reduce its efficiency.

A routine cleaning of the water softener becomes necessary to keep your system performing at its peak.
The opportune time to clean the water softener is when the softening salt is running low, to avoid emptying all the salt in the system.

Two Methods on How to Clean a Water Softener

Cleaning the Resin Beads

The first method involves cleaning the resin beads. Commercial resin cleaners work by replacing the accumulated minerals with sodium ions. Some cleaners remove all the mineral build up while others target a specific element e.g. an iron mineral-removing product added to the water softener, would dissolve the iron particles present and make them liquid. It will now be easy to rinse with water. Choose the product that is recommended for your water softener.

Follow the instructions provided by the manufacturer, and pour the recommended amount of resin cleaner in the brine tank or salt tank of the water softening system. The sodium ions present in the resin cleaner will remove the buildup minerals and clean the resin beads.

Cleaning the Brine Tank

  1. Disconnect all the pipes from the water softening unit. Remove all the water present in the resin tank and empty it carefully in the drains. Don’t pour it on the lawn.
  2. Get rid of any left-over softening salt in the unit. If the water softener has big blocks of salt in it, use hot water to break them up and scoop the salt out.
  3. Use dish washing soap and a few liters of water to make a soapy mixture. Pour the soapy mixture into the tank and scrub thoroughly using a long-handled brush. Discard and rinse with clean water.
  4. Further cleaning follows using a bleach solution follows. Use a ¼ cup of household bleach e.g. vinegar on 4-5 liters of clean water. Stir carefully and let the solution sit for 15 minutes. Pour it into the water softener and scrub once more with a brush. Dump the bleach water and rinse using a lot of clean water.
  5. Finally, reassemble the system and pour 5 gallons of water in the brine or salt tank. Add water softening salt to the tank – a 100 pound bag of salt is recommended. The tank should contain at least one quarter full of water softening salt at all times. For increased efficiency, do not fill up the salt to the brim of the water softener.
  6. Leave a gap of about six inches from the top of the tank.

  1. Thanks for posting how to clean the water softener. We have a puronics water softener and filter. We were told we need to have service on it that will cost 250.00 dollars. I asked what was involved with this fee. Here is the answer: “The standard procedure is replacing the reverse osmosis filters, do a 9 point inspection, check everything is working the way it should be, and top off the salt in the whole house water softener. ” What filters? We have 1 water filter specifically for drinking water and the rest of the house just goes through the regular tank and salt process. Not sure what 9 point inspection they are referring too. Can someone tell if this is a typical service fee? I was under the impression that they would clean out the brine and the actual salt container.

  2. My well water is extremely rusty. I switched from the green bags of rust remover to a 1/4 cup of this mixture and it works better than the green bag and costs a lot less in the overall price. very easy just add 40-pound bags of salt to the salt storage bin and sprinkle 1/4 cup of Rust Out on the top layer of the salt you just dumped in. Layer it 40 pounds at a time with 1/4 cup of Rust out sprinkled per bag. It works great!
