I just buy the big rubbermaid tubs from target and wash them out with scentfree laundry detergent. Let em dry and throw about a dozen "dry" (so they won't rot) leaves in the bottom and then one of those arm and hammer boxes of scent absorber baking soda.

So far no problems, but nothing that goes against my skin like long underwear or t shirts and such goes back in the container, it all gets washed scent free and stuck back in after it dries.
