Restore Performance. Build Repeat Business. 

Res Care® is the industry-standard resin cleaner that restores water softeners to peak efficiency—while helping you deliver better results on every service call. By removing the contaminants salt leaves behind, it keeps systems running stronger, longer, and more consistently.

Solve the Problem Most Customers Don't See

While salt handles hardness, it doesn’t remove iron, manganese, silt, and metal buildup inside the resin bed. Res Care targets these hidden issues—helping you prevent performance loss, extend system life, and reduce callbacks.

WHY CONTRACTORS RELY ON RES CARE

RESTORES PEAK SOFTENER PERFORMANCE - Removes iron, manganese, silt, and metal buildup that reduce efficiency and flow rates

EXTENDS SYSTEM LIFE - Protects resin beads and internal components from fouling and long-term damage

PREVENTS FUTURE PROBLEMS - Use at every regeneration to maintain performance and avoid costly service issues

FAST, SIMPLE APPLICATION - Liquid formula pours directly into the brine well—no complicated process

SERVICE-CALL READY DOSING- Pre-measured 4 oz. option makes routine maintenance quick, consistent, and easy

TRUSTED + CERTIFIED - NSF/ANSI/CAN 60 certified for use in potable water systems

SYSTEM-READY INTEGRATION - Pairs with the Easy Feeder® system for continuous, automated maintenance

Build A Stronger Maintenance Program

Res Care makes it easy to turn every service call into preventative maintenance—helping you protect customer systems while creating consistent, repeatable revenue.

Use Res Care on every service call to restore performance, extend system life, and keep customers coming back.

A Smarter Way to Care for Your Water Softener

Your water softener works hard every day to reduce hardness in your water. But over time, iron, manganese, silt, and other buildup can collect inside the system — even when you’re using salt regularly.

Res Care® is a professional resin cleaner used by water treatment contractors to help keep water softeners performing at their best. It cleans the resin bed inside the softener, helping the system work more efficiently and consistently.

Why Homeowners Ask About Res Care

Helps restore softener performance
Res Care removes buildup that can reduce your softener’s efficiency and water flow.

Cleans what salt leaves behind
Salt helps with hardness, but it doesn’t remove iron, manganese, silt, and metal buildup inside the resin bed.

Helps extend system life
By keeping the resin cleaner, Res Care helps protect important internal components from fouling and long-term damage.

Helps prevent future problems
Regular maintenance can help your softener run more consistently and may reduce the chance of service issues over time.

Certified for potable water systems
Res Care is NSF/ANSI/CAN 60 certified for use in drinking water applications.

Available for ongoing maintenance
Your contractor may recommend using Res Care during routine service or adding an Easy Feeder® system for continuous, automated maintenance.

DIRECTIONS FOR USE (READ ENTIRE PRODUCT LABEL BEFORE USING):

First Application for a Fouled Unit

Use 4 oz. (1/2 cup) of Res Care per cubic foot of softener resin. Note: Most residential softeners contain approximately 1 cubic foot of resin. If unsure, check your owner’s manual. Pour Res Care directly into the brine well. If your softener has no brine well, pour Res Care directly into the salt tank when the salt is low. Manually regenerate the softener. NOTE: If taste or odor is detected in tap water, manually regenerate softener, then run cold water until odor is gone.

Regular/Maintenance Use

Add 4 oz. (1/2 cup) per cubic foot of resin at each regeneration.

Frequently Asked Questions

Pro Products

Res Care® is a liquid water softener cleaner that removes iron, manganese, and other contaminants from resin, restoring system efficiency and performance. It is widely used by both contractors and homeowners to maintain softeners and extend the life of the resin bed.
Salt regenerates the softener, but it does not remove every contaminant that can build up inside the system. Res Care® helps clean iron, manganese, silt, metal particles, and organic compounds from the resin bed to support better softener performance.
For severely fouled units, pour 4 ounces (1/2 cup) of Res Care® per cubic foot of resin directly into the brine well. If the softener does not have a brine well, pour it into the salt tank when the salt level is low. Then manually regenerate the softener. If taste, odor, or discoloration is detected in the discharge, repeat regeneration and run the nearest cold soft water tap until it clears.
Res Care® should be used regularly to help maintain softener efficiency, especially in water with iron, manganese, or other fouling contaminants. Homeowners can use it for routine maintenance, while contractors may recommend more frequent or continuous use in problem-water conditions.
Res Care® helps address resin fouling caused by iron, manganese, silt, metal particles, and organic matter. Regular use can help restore softener efficiency, improve performance, and extend the life of the resin bed.
Yes. For manual application, Res Care® can be poured directly into the brine well. If there is no brine well, it can be poured directly into the salt tank when the salt is low. It can also be used with an Easy Feeder for more consistent, automatic maintenance.
Res Care® is NSF certified to meet NSF/ANSI/CAN Standard 60 for drinking water additives. That certification makes it a strong option for contractors and homeowners who want a resin cleaner formulated for use in drinking water treatment systems.
The Easy Feeder automatically dispenses Res Care® during the softener’s regeneration cycle, helping keep the resin bed cleaner with less manual effort. It is a practical option for homeowners and contractors who want consistent, ongoing maintenance.
No. Res Care® helps clean fouled resin and improve softener performance, but it will not fix mechanical issues, undersized systems, failed components, or water problems that require additional treatment.
Res Care® is useful for both, but it is especially valuable in service situations where contractors need a reliable way to restore and maintain softener performance in challenging water conditions. Homeowners can also use it as part of a regular maintenance routine, particularly when their water contains iron or other contaminants that salt alone cannot fully address.
