How do I Use Muratic Acid to Clean Tile?

Though it's strong, muratic acid will clean tile-covered areas.

Muratic acid is a type of highly corrosive acid that's sometimes used in pool cleaning and is available commercially. Though it's fairly dangerous, with the right tools and preparation, it's possible to clean tile with the acid.

Safety First

Cover your face with a respirator, complete with acid-grade filter. Wear long sleeves and long pants and cover your hands and arms with rubber gloves. Open all the windows in the room first to provide more ventilation for the space.

Mixing

You must mix the muratic acid with water before using. Fill a plastic bucket with 10 parts water and then slowly add in 1 part muratic acid. Use a plastic bucket because other types of materials can cause a chemical reaction when the acid is added.

Cleaning

Apply the water and muratic acid solution to the tile using a dry brush. Work on one area at a time and work quickly. As soon as the tile is clean, rinse off with a damp towel and begin working on the next spot.
