Features

  • Water Softener Cleaner: Maintain optimal water softening system performance with this multi-purpose cleanser. Its formulated to rid contaminants that salt leaves behind, including iron, manganese, silt, metal particles, and harmful compounds.

  • Easy to Use: Manually add an entire 4 oz bottle of the resin cleanser before each regeneration. For best results, pair with Pro Products Easy Feeder kit (sold separately) to provide your water softener with a low, consistent dose each day.
  • Drinking Water Peace of Mind: Res Care is NSF Certified to meet NSF/ANSI/CAN Standard 60 for drinking water additives. Made in the USA, our water treatment helps provide peace of mind with suitable drinking water for families and pets.
  • Professional-Grade Formula: Created by professionals and backed by a deep commitment to customer support, we help home and business owners simplify maintenance while protecting their water softening investment.

Description

Rest easy with Res Care Liquid Water Softener Cleaner. It cleans what salt leaves behind and is easy to use. First Application Instructions: Use 1/2 cup (4 ounces) of Res Care per cubic foot of softener resin. Most residential softeners contain approximately 1 cubic foot of resin; if unsure, check your manual. Pour the cleaner directly into the brine well. If there’s no brine well, pour directly into the salt tank when salt is low. Manually regenerate the softener. If taste or odor is detected in tap water, manually regenerate softener, then run cold water until the odor is gone. Regular Maintenance Instructions: Add 1/2 cup (4 ounces) per cubic foot of resin at each regeneration.

  • Easy Maintenance for my Water Softener!
I’ve been using a water softener for a few years now, but I hadn’t realized just how much gunk and buildup could accumulate inside over time. I picked up this cleaning solution as part of a routine maintenance plan, and I’m honestly surprised at how much of a difference it made. Ease of Use: Super straightforward — just poured the recommended amount into the brine well during a regeneration cycle. No tools, no disassembly, no mess. The instructions on the bottle were clear and easy to follow. Immediate Effects: After just one use, I noticed a definite improvement in water softness and pressure. My faucets aren’t showing that chalky residue anymore, and the dishwasher is rinsing cleaner with less spotting. Scent/Chemical Note: No strong odor, which I appreciated. Some cleaners can be harsh-smelling, but this one was barely noticeable. Value: Considering how much a new softener system costs, this cleaner feels like cheap insurance. I plan to use it every few months to keep things running smoothly. Final Thoughts: If you have a water softener and haven’t cleaned it in a while (or ever), this is absolutely worth adding to your maintenance routine. A small step that delivers noticeable results ... show more

  • Don't call a plumber!
I went 16 years without cleaning the system, I didn't know any better, I thought the auto regeneration every 1000 gallons or so was doing that. My water pressure was dropping and i googled and found out it needed this kind of treatment every few years, I added a bottle and started a regeneration cycle for that night and the next morning the water pressure was back, the tank wasn't filling up with water and using up all of the salt, and now it runs efficiently and good as new! ... show more

  • Leaked all over
I like the easy to use size but there was no inner seals on the bottles and it leaked all over. I ended up using 2 bottles the first time to equal 4 oz.

  • This really works!
I didn't think this would make much of a difference with softener performance, But I noticed my water has become even softer after adding this to the tank. I will be using this from now on.
