I have put foodsaver canisters in my freezer. I use them to keep/save

the seals have failed from freezing or they just get knocked about in
the freezer. Reason hasn't been determined.

I like to make icecream but don't necessarily eat it very promptly. I
thought perhaps storing it in a Foodsaver canister would help it last
better. My question is, are the canisters safe in the freezer? I assume
that the container plastic (polycarbonate I think) is fine, my concern is
the rubber/elastomer seals on the lid and whatever is inside the little knob
that the tube goes into. I haven't investigated or thought about what kind
of valve is there or whether exposing it to temperature cycling is
advisable.

Similarly, I am curious about how best to clean the lids after they have
been in contact with meat juices and such. I believe the manual says to
simply wipe it with a damp cloth or something like that, but that leaves me
concerned about contamination. Is there a way to sterilize these lids?
What would happen if it were put in the dishwasher, or into boiling water?
What if they were steamed?

Thanks in advance for responses,

Jafar
