    My dad had 3 big jugs of phosporic acid...we only have about 3/4 of 1 left. Maybe around 10 gallons.
    What can this be used for? I know we use it in our pool a bit, and I think my dad used it to help our water from the well, and I think he used it for other things too...but what else?
    It's just sitting doing nothing right now...

    I used it once to remove mortar off rocks from a rock wall I helped build.

    I have used it for cleaning tarnish off brass and copper. Also works well at cleaning aluminum. Wear gloves and don't splash it on you!!! Also use outside only, the fumes are very nasty. Use baking soda and water to neutralize the acid, when you are done cleaning an object with the acid, and rinse it a bunch.

    Naval Jelly!

    Its the main ingredient in Naval Jelly,and many "rust reformers" paint stores sell--it turns rust into a black substance that resists rusting again for quite a while....not sure in its pure form how good it works..and it will cause nasty burns,so use gloves and eye protection if you use it on your cement..be careful.. :crazy:

    That looks like a poem...every second line rhymes with the line before it...
