Steve,

A chlorine bleach solution should be enough, but, as you said << Lots of
rinsing afterwards would be essential. >> I'd consult a materials safety expert
before I would mix anything with the bleach.  My ever impetuous old man once
mixed some bleach with dish detergent in the kitchen sink and then spent a couple
of days relaxing in the hospital after he was overcome by the fumes given off
by that concoction.
