Wonder if Tupperware would have replaced the freezer containers that my mother-in-law ruined for me. We'd stored some stuff at their house when Uncle Sam sent us to Foreign Country #2. For some strange reason (she said "to keep the damp out of them") she put mothballs in them! So when I got them back 3 years later, that camphor stench had permeated the plastic. I tried everything that people suggested, hand washing, machine washing, scrubbing with baking soda, letting them sit out in the sun for several days, but nothing worked. I finally threw them away because I couldn't trust that the smell wouldn't ruin the food in them.
