Storing tins in a damp environment

[Geordie_Rob]

Looking for helpful advice on this one please.

My wife still thinks I'm crackers for trying to prep for things going wrong & won't have more than 4 weeks food in the house, which is fine if any event only lasts 4 weeks & only if it waits until we have been shopping 1st. However back in reality, I know it won't be like that.

My only storage option is my shed which gets damp & has had mice the past 2 winters. I'm hoping I've sorted the damp via air holes drilled into the doors but can't guarantee it. My thoughts for storage was the plastic storage boxes with tinned food inside & on the top layer, have an open tub of salt or rice to absorb any moisture trapped in the box & a lid on the storage box to try & exclude more air getting inside (I know I can't eliminate all of the air holes, but I can try).

Basically, I'm hoping the rigid plastic tubs raised off floor level will be enough to stop any mice from getting in & the salt or rice will absorb any moisture to stop the tins rusting. Does anybody see any problems with this method & have any alternative ideas (other than a new wife )?

Thanks
