Muriatic Acid Useful Life or Expiration Date

[JimK]

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!

Interesting. I like the third option. Is there a certain amount of water I should use for each gallon of MA? I’m not sure the exact amount I still have...will have to look tomorrow.

Thanks.
