me and printer want to remove passivation from some ICs. the obvious solution is HF, but, unfortunately, our chemicals supplier only has it packaged in five point five liter canisters ($30 each, natch)

how do I safely dispose of five liters of hydrofluoric acid

@whitequark I think somebody mentioned dental diluted HF gel on one of the hacker cons. I don't decap so I have no hands on experience with it.
