How long does Muriatic Acid last in its original gallon bottle? I have some that must be at least 3 yrs. old. Thanks.

Forever! It does not go bad.
BUT . . . and this is a HUGE BUTT . . . the bottles do go bad, if exposed to sunlight. And, a brittle old bottle can crack open without warning, spilling acid everywhere.

That reminds me, I have a couple bottles of MA that are years old (stored outside in a plastic, covered garbage can). Since adjusting TA and adding borates years ago, pH has been rock solid, so I haven’t had to add acid.
This thread reminds me I need to contact the city to find out how to properly dispose it.

That could be problematic. HAZMAT fees can be horrendous.
Here are some alternatives:
- Give it to a brick or masonry contractor.
- Give it to pool contractor
- Add it to 5 gallons of water in a plastic garbage can; add "washing soda" till it stops foaming; pour it down the tub. It's just salty water at that point!

2 gallons of water to 1 gallon of acid will stop the 'fuming' or release of hydrogen chloride gas. This is important, since sodium carbonate (washing soda) + hydrochloric acid (muriatic acid) => carbon dioxide + salt. The carbon dioxide is what will be bubbling up . . . but if the acid is still concentrated will facilitate the release of acid gas fumes.

This is not about the thread so please delete after reading.
I joined this forum back in 2014 and I am still unable to post questions or answers.
How long do I have to wait to be able to do these?
Was I overlooked or denied for some reason?
Please help me to be able to access these because I have questions I could really use some help in figuring out problems with my pool. Especially with my very high ph level at this time.
Thanks in advance,
