[TheForge] Removing Zinc and Cadium

[GRAF]

I did not say that I would drink it for disposal.<G>
Sometimes folks tend to dump all things bad for us into the same category.
Zinc oxide is one of the active ingredients in diaper rash ointment and 
some sun block lotions.

I wouldn't eat that intentionally either, although I am certain to have 
ingested some sunblock along the way.
I do not think a quart of vinegar/zinc oxide solution from stripping a 
pound or two of bolts poses an environmental risk.

Being very NON PC I'd say turn on the tap and flush it.
About the same thing as dumping some pickle juice and taking a shower 
after a picnic lunch at the beach.
