Muriatic acid sold at masonry supply businesses.

Yes, acid will do the trick. I've heard muratic acid works (nasty stuff to work with). My uncle recently completed a brick job at our house and he had good luck with a toilet bowl cleaner!

I think the above posts were referring to acetic acid. Vinegar is a weak acetic acid, and you can buy much stronger industrial strengths.
Why not paint it?

Acidic Acid, it is VERY strong and should be used in a well ventilated area. Or call your local brick company and explain what happened, they probably have the answer.

That could be tough. Professional masons use acid to remove it.

If your grout is not synthetic, vinegar and a stiff brush should work (not a real hard brush-it will scratch the tile)-a hard tooth brush or even a nylon pot scrubber. You will have to put a little elbow grease into it.
