4 Things to Know About Cleaning Calcium Scale Off a Salt Cell
Calcium scale is harmless White crust on the titanium plates is just calcium carbonate from hard water, high pH, or high alkalinity. It won’t damage the cell if cleaned properly.
Soak in diluted acid, don’t scrape Mix a 10:1 water-to-muriatic acid solution, or use white vinegar for light scale. Soak the cell for 5–10 minutes, then rinse with a hose. Never scrape with metal tools—the titanium coating is tough but can be scratched.
Manual cleaning is still necessary Some cells have a reverse-polarity cleaning cycle, but it’s not enough if you see scale. Clean manually every few months to avoid early failure.
Regular cleaning saves money A $500 cell lasts longer with occasional manual cleaning. Skipping it leads to buildup that forces early replacement.
