Tupperware for produce, yes-- with air holes cut in if they aren't already in the T/ware. Line with a damp towel. Bleach as needed (monthly)? Take all produce out of bags/boxes.

Too few people for DW is if you have two people and not every meal is eaten at home, it does not come close to filling the DW even if you put the pots and pans in. Water comes dear in some places.
