Storing tins in a damp environment

[CharlesHarris]

If the tubs have air tight seals the tins won't rust. Otherwise i would stack the tins in watertight, containers, or shrink wrap cardboard cartons containing them. An old,nolonger used refrigerator makes a good storage locker for tinned goods and protects them from heat, light or rapid temperature changes which cause condensation of ambient moisture from the air, which would cause the tins to rust.
