Muriatic acid

Holy frijole...I haven't poured anything that smoked since college chemistry class. Got a whiff of it and I'm sure that was a blunder. I'm amazed you can still buy this stuff. I got some to clean up ceramic planters and I'm thinking I should have just got new pots. I was going to do the toilet clean with it, but that's out.

Any experience with this stuff?
I always used it to clean bricks after laying them. I have no fingerprints
