If I put CLR in a plastic container to clean something, how long and how much should I clean it before I can use it again?

Cleaning a knife with CLR and and put it in a plastic container that we use. Not sure how much is it needs to be cleaned before I can use it again or if I can use it again at all.

The container should be discarded.
It is unsafe for food, because toxic chemicals will have leeched into the plastic.
OR retained for use in storing unedible items, (screws, nails, small parts, etc.)
