Muriatic is (or turns to) Sulfuric (or is it Hydorchloric?) acid.
For a small job, it might be manageable. For major square footage,
it can get out of hand. Truly Nasty Stuff.


Muriatic acid is usually about 32% hydrochloric acid, and
the rest water. Hydrochloric acid is essence of vomit.

It's a real acid. *I* wouldn't have called it "truly nasty",
but you do want to treat it with respect.
