    Can old liquid chlorine cause problems?

    Hello,

    When I moved to my current house last year, I inherited several Pinch a Penny containers half full of liquid chlorine. I'd like to return these to get the deposit back and get them out of my shed.

    I understand the chlorine levels are deteriorated. Can I pour this into my pool without causing any damage? I'd rather not pour this down my sink or deal with bringing these back without emptying them first.

    Thanks

    Bill

    Basically it will degrade into salt, water, and oxygen, so it should be fine to pour into the pool. Just check the containers first and make sure they still contain chlorine and that the old owners didn't reuse the containers for something else.

    Thanks. I didn't know what it would turn into.

    Forgot to mention I have a few containers of acid. Those will actually be useable, correct?

    Yes, MA keeps indefinitely. Just be sure to open it in a well ventilated area with the wind at your back.
