How much muriatic acid is needed to properly clean dirty ceramic tile floors?

Last updated: October 17, 2026 8:00:00 AM

You generally need about one part muriatic acid to ten parts water for cleaning ceramic tile. Always test a small area first and rinse thoroughly with clean water afterward.

Cleaning dirty ceramic tile floors with muriatic acid requires a dilution of one part acid to ten parts water, mixed strictly in a well-ventilated area while wearing heavy protective gear. Because muriatic acid is a powerful, highly corrosive form of hydrochloric acid, it should only be used as an absolute last resort when standard, gentler cleaners have completely failed to remove deep-seated mineral deposits, severe efflorescence, or heavy construction grime.

Neutralization and Thorough Rinsing
