Folks that store it in a pool pump house or mechanical room that has equipment will experience the rusting of metal. Same for storage in a garage. Sometimes I see pool service guys that have rusted beds on their pick-up trucks. I place my gallon jugs outside in a 5 gallon bucket with a top on top without closing it tightly. |

Sometimes I see pool service guys that have rusted beds on their pick-up trucks. I place my gallon jugs outside in a 5 gallon bucket with a top on top without closing it tightly. I had access and use of hydrochloric acid in the lab but had bought the gallon when I moved into my new house and wanted to paint the basement floor. I wanted to clean and etch the concrete with the muriatic acid. Besides my storage mistake, I had used a sponge mop to apply the diluted muriatic acid and near the end of my work the sponge fell apart from decomposition of what must have been a polyurethane sponge. Good url on household use. I should also mention rule of thumb that you always pour acid into water to dilute and never pour water into acid. Water added to acid, particularly sulfuric generates a lot of heat and can be enough for an eruption that will cover you with acid causing severe burns. When working with strong acids or caustics, you always want eye and skin protection. |

For most of my life I bought toilet bowl cleaner i cardboard cylinders with plastic insert caps. Then I bought more than I needed, and the last container say under the bathroom sink for years. When I finally noticed it, the paper was bubbling and the electric heater under the same sink had pits in the chrome. It was really a shame because it was the heater my parents bought when I was born, to warm the bathroom before bathing me. It was in perfect condition before, even the cloth cord, at age 60 or so. It has an on/off switch operated by stepping on it. The heater still works fine, and I cleaned the pitting up a lot with rubbing compound, but it's not the same anymore. Do they still sell toilet bowl cleaner in cardboard containers? |

I wanted to clean and etch the concrete with the muriatic acid. I've always heard the muriatic acid WAS used to etch concrete slabs for paint or epoxy coatings. I was just given (10 days ago) a two part epoxy floor coating (Behr). Enough to do the single garage. Watching a videos I see they use the two packets (white powder crystals) of Citric Acid Anhydrous to etch the floor and scrub it. This breaks the seal if you have one. One that acts almost like muriactic acid is a tile and grout cleaner I have used. Sulfamic Acid crystals (treat the same as muriatic - add to water - not the reverse). I spilled a drop on an paver and the spot looked like a new paver. I'm not a chemist. Care to comment on each? |

It's a great descaler so it does not surprise me that it can be used to etch concrete. It's used in dishwashers when drinking glasses start coming out with a haze on them. Sulfamic acid is a pretty strong acid but not as strong as sulfuric acid. It is, however, much safer to use. It is certainly strong enough to etcgh concrete as it is also used a s adescler in things liek CLR. |

http://www.newton.dep.anl.gov/askasc.../chem03286.htm I would not use muriatic acid anywhere inside the house. The only use I have for it is to soak the 'fingers' of my inground pool filter or use it as a herbicide to kill grass and weeds around the pool and other concrete walks. (I have a 4' wide concrete walk around the pool and then a 3' wide loose stone area to the security fencing) -- Bill In Hamptonburgh, NY In the original Orange County.

When working with strong acids or caustics, you always want eye and skin protection. I have a pool house where all the pool equipment is stored in a cheap tall cabinet. I usually leave my large plastic tub filled with 3" chlorine tablets outside the pool house over the winter, but my wife said the tablets seemed to lose some potency outside, so I stored the tub in the cabinet inside the pool house at the end of Summer. Next spring, when I started to get the pool ready for the Summer, I opened the cabinet and saw all the european type hinges rusted to the point where they looked fuzzy. -- Bill In Hamptonburgh, NY In the original Orange County.

They were solid, like small gravel, crysltals maybe, but not liquid. Liquid toilet bowl cleaner is relatively new. |
