    Leftover chemicals

    It's been an uneventful summer and I am thankful! I have a few gallons of leftover liquid chlorine which I store in an unheated location. Will it freeze?

    Don't bother storing it! I don't have the numbers on it's breakdown in front of me, but it won't be much more than colored water come spring!

    I'd either use it in the pool or use it over the winter to clean your toilets and bathtubs [I use diluted 12.5% to spray down my toilets and all the areas in my showers that show the pink biofilm common in the North East]

    Liquid chlorine (sodium hypoclorite) breaks down to ~ 1/2 strength in ~ 240 days [when kept in a cool and 'sun free' area] The breakdown is quicker when the % is higher, but... bottom line is to use it before you loose it

    You can also use it to get rid of mold or mildew on decks, etc.

    Have a great winter - I hope we'll still see you here in the cold months!

    De Nada!

    One other reason not to store chlorine inside is that it will outgas and start attacking any metals in the room
