Review: Powerful stuff - I use this, diluted, to remove calcium carbonate deposits from saltwater aquarium equipment. Works perfectly, and reagent grade means I'm not added unwanted contaminants to my reef systems. :)
Review: Hydrochloric Acid - effective but dangerous. - I bought some Hydrochloric Acid 37% Reagent Grade as a last resort, to clean my stained toilet after many unsuccessful attempts with worthless You Tube type remedies. My toilet had lime and rust stains that had resisted all previous cleaning attempts. The Hydrochloric Acid worked quickly and effectively, but it is DANGEROUS and if you intend to use it you MUST follow strict safety precautions i.e. eye protection, face masks, ventilation (switch on extractor fans), don't sniff it. I plungered out most of the water from the toilet, poured in half (about a pint) of the Hydrochloric Acid, watched it fizz and bubble, then ran away for about 20 minutes. On my return, behold, a sparkling clean toilet - all rust and lime stains had gone. Depending on the amount of staining, 20 minutes may not be long enough. Let me re-emphasize this is powerful, dangerous stuff. Please read all safety instructions and know what to do in the event of an accident.

A: By mass. 12 molar

**Q: What are the ingredients -- Hydrochloric acid and water and nothing else??**
A: Its 63 percent water and rest Hydrochloric Acid

**Q: Can this be put into a lead acid battery?**
A: I thought lead acid batteries used (diluted) sulphuric acid.  DON'T DO IT.

**Q: I used to use a product call tnt for cleaning grout.   it was hydrocloric acid...  will this be similar? has anyone tried it?**
A: This would work if dilutes otherwise it would very aggressively attack the grout. In all honesty you can find Muriatic Acid at most hardware stores for a few dollars per gallon that is the similar to this but already diluted and at a much lower price.
