How To: Use Muriatic Acid
Muriatic acid can be used to clean pools, concrete, hardware, and plumbing. Here is everything you need to know to use this cleaning solution safely.

I had one gallon of MA in my storage building that sat for years on end. While it was there, any brass or metal tool or fitting corroded or built up rust on it. The brass fittings on my tools turned a weird brown color. And bubbles started forming on the plastic jug of the chemical. It's so weird how it was able to do all that damage even when the jug was tightly closed.

What did those look like when new?
They’re getting better but not perfect yet. I soaked the tiles overnight in the acid. It ate through a bit of the deposits but not all. I’ll soak them in CLR next.
What I’ve learned so far. Muriatic acid is some nasty stuff. Wear breathing and skin protection. Also I learned this stuff is great for releasing grout. It made all the grout turn into sand and just fall apart off the tile. So, if you guys have a job with porcelain tile with grout haze everywhere, clean it with muriatic acid. Wear protection and ventilation is a must.

Isnt CLR just sulphamic (sp?) acid? How strong did you mix your MA? Maybe mix lil bit stronger
Oh no, I poured it straight in. It was strong. I don't know the make up of CLR. All I know is it's calcium specific.
I don't think so..

thats how I first learned to do it, had a large area covered in haze
spoke to an old school tile installer, he came and looked at it and sorted the whole floor in time it took me to do a fraction

I have not used muriatic acid indoors since 1993 when I learned that the fumes turn chrome plating into gunmetal blue. And it is permanent. Iirc, I was regrouting a bathroom on a Coast Guard base and thought the acid would etch the old stuff.
It did.
It did.
