I remember in high school we had to wash beakers with sulfuric acid to make sure there weren’t any traces of heavy metals left.

AHEM. Ackshually petri-dishes are mostly made of plastic these days and discarded with the rest of the biohazardous waste… At least in microbiology labs.
Also I love the word autoclave.
