10 years old Die hard Gold

Personally, i like Rusty's idea of dumping the old acid in the dirt and flushing it out with clean water.
You could probably fill a 5 gallon pail with the old stuff including the flushings and drive across town to dump it so you don't get caught dumping it near your home.
I would go at midnight, under a full moon, and dump it in your least favorite politician's back yard or alley.
And then howl at the moon..................
Awoooooooooooo!
