To clean a valve cartridge, soak it in white vinegar, then rinse it thoroughly.
Here's a more detailed breakdown of the process:
Steps to Clean a Valve Cartridge:
-
Remove the Valve Cartridge: Carefully remove the valve cartridge from its housing. Refer to the manufacturer's instructions for your specific faucet or shower valve to avoid damage.
-
Prepare the Vinegar Soak: Fill a container with enough white vinegar to completely submerge the valve cartridge. White vinegar is a mild acid that effectively dissolves mineral deposits and buildup.
-
Soak the Cartridge: Place the valve cartridge in the container of white vinegar and let it soak for at least one hour. For heavier buildup, you can soak it for longer, even overnight.
-
Flush the Valve Housing (Optional but Recommended): While the cartridge is soaking, take the opportunity to flush the valve opening with water. This helps remove any loose debris and ensures a cleaner valve overall.
- Turn on the water supply briefly to flush the valve housing.
- If it's a shower valve, it's generally recommended to start with the cold water side to avoid potential scalding from hot water that may have been sitting in the pipes.
-
Rinse Thoroughly: After soaking, remove the valve cartridge from the vinegar and rinse it thoroughly with clean water. Use a soft brush (like an old toothbrush) to gently scrub away any remaining debris.
-
Inspect and Reassemble: Inspect the cartridge for any signs of damage (cracks, broken seals, etc.). If damaged, it's best to replace the cartridge. If it looks good, reassemble the valve according to the manufacturer's instructions.
Why This Works:
- White Vinegar: The acetic acid in white vinegar dissolves mineral deposits like calcium and lime that accumulate over time and can cause the valve to malfunction.
Important Considerations:
- Safety First: Turn off the water supply before removing the valve cartridge.
- Manufacturer's Instructions: Always consult the manufacturer's instructions for your specific faucet or shower valve.
- Replacement: If cleaning doesn't solve the problem, or if the cartridge is damaged, consider replacing it with a new one.
