same here with the dish washing without soap.a hot water rinse and a clean flour sack type dish towel is all i use unless grease is involved,people don't wash beer glass's in soapy water do they?
on canoe/camping trips i don't use soap on any of the pots and aluminum pans,just boiling water and air dry.
we have so much stuff,food wise,that is so easy to get that i don't think folks even think about trying to keep food,they just chuck it if they think it's "old" and buy new.the right storage container is a must.i'll have to admit that i had to throw out an unopened bag of bread flour because i left it in the bag in our basement food storage shelf along with the canned goods.over the summer it went moldy,which is why they sell flour canisters that seal isn't it...
