    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?

    Yea, I use it all the time for badly rusted stuff and removing water deposits from glass.
    10 minutes and rust is gone completely.
    You gotta be careful with this stuff, and NEVER breath the fumes or you could end up with chemical Pneumonia and basically drown in your own fluids. (not good)
    It's watered down hydrochloric acid.

      It's used in small engine repair to remove aluminum deposits from the crankshaft where the crank rides on the aluminum engine case without a bearing when the engine kicks a rod or rods from low oil. Whew, my English teacher wouldn't like that run-on. lol

      Yeah, they take the "oomph" out of carb dip and a zillion other things, but we're still "ok" with that stuff.

          I wouldn't do that unless the house was cleared of everyone and I had a good chemical mask.
          Take it off and outside I would do it.

            Yes, stuff is nasty to use, use a charcoal respirator and do it outside. Then rinse your parts or whatever with baking soda and water to neutralize the acid, final rinse with distilled water helps it not to flash rust quite so quick when working with steel.

            Rinse and blow dry right away.

            Used it on a small area on the under body of a mopar just in front of the rear wheels on the underbody.

            Clean, Dry, Prime and Paint . . Brand New
            Good bye surface rust.

            For sure use saftey glasses and rubber gloves when working with the chemical acid. Long sleeve shirts too, one spec can burn like Hell. Fush with water if you get any on you.

              Hyup, same uses as above.
              With hard well-water, it makes short work of the scale. for 2 or 3 bucks a jug back in the day, it saved me from having to buy many a new toilet.
              And Like said; it eats aluminum, so great for cleaning up piston-transfer in a cylinder. But man it's hard on the nose if yur not careful.And yes it will dissolve your fingerprints........

                Be careful with this stuff. A very strong acid with low pH. Used to etch concrete amongst other things. Make sure you have all the proper PPE when handling and never add water to this (or other acids).

                My son cleaned the floors of his garage and didn't ventilate properly.
                Had extensive pitting damage to chrome/brightwork on his vehicle and chromed parts
                Be careful, chrome easier to replace that one's lungs!

                  Cleaning concrete off crusty mixer trucks, doesn't take much.
                  That pesky galvanizing on that pipe you need to weld, no problem.
                  Well ventilated area, don't wear clothes you're not afraid to throw away.

                    I think it is also called "Milk Stone Remover". Used by dairys to flush the milk house pipes.

                    Used that to dip my rusty rims in. Cleaned them up like magic. Flash rusted in s matter if minutes but it wipes off. Goid call on distilled water rinse after baking soda. Neutralized acids using a base creates salt,vthays what you need to get off to prevent rust. A plastic yard waste can from home depot was perfect size for a 14 Rallye rim. Fill with gallon buckets of water to see how much it will take to just cover rim, then dump and add water minus 2 gallons. Fill rest with pool acid slowly to avoid splashing. Always add acid to water or a violent reaction can occur adding water to acid! Let it set checking every 10 minutes. Then remove and dunk in neutralizing bath of base, baking soda mix. Finsl rinse or spray down with distilled water. Does pool acid etch toilet bowl?

                      Muriatic is same stuff as battery acid, different concentration.......hydrochloric. Also, we used to use it to clean water-to refrigerant heat exchangers, "coil clean" I still have some it. THAT last stuff is pretty concentrated, and you want to be careful

                      Back when we had "real" auto parts stores, many carried battery acid, and if you had a container you could buy a little, or with a little more money, buy a container. They came in different sizes, don't remember. Seems like the smaller was about enough to fill a dry battery, and the larger container was maybe a couple? gallons.

                      And back when we had "real" chemical supply houses, ----and they weren't worried about registering and licensing every damn thing, they could also sell you various types

                      Battery acid is sulfuric acid not hydrochloric acid.
                      Your muriatic acid is hydrochloric acid.

                        Citric acid smell and is much friendlier and still does the job of derusting most stuff.
                        It also comes in soda drinks and soaps.
