Yes I got lucky they weren't too dirty and no lifeform had started to
use the floppies as lunch.
Also depends on glues holding the oxide on, would be worth an
experiment with soaking. Or keep dry (to stop lower lifeforms from
spreading) and store till a good method is found. Against further
storage is the fact that a dry atmosphere may also cause some damage
to the oxide (dry out lubricant) or base material (some plastics
outgas and go brittle).
