Where to Find Muriatic Acid

Muriatic acid.

Danny, On one of your episodes, Joe Truini said that muriatic acid would remove scum and water deposits from tile in a bathroom. What I need to know is where can I purchase muriatic acid? – Denise

Hi Denise,

Muriatic acid is used to remove excess mortar from bricks and to balance the pH of swimming pools, so it can often be found at both home centers and pool supply stores. Look for it in the building supply or gardening sections.

Muriatic acid is strong stuff, so be sure to read all the precautions and follow directions including wearing rubber gloves and eye protection. Dilute it with water following the directions on the container before using and make sure there is adequate ventilation.

You can read and watch the video on Joe Truini’s method of cleaning bathroom tile with muriatic acid on our website at How to Clean Tile with Muriatic Acid.
