A lot of my food is canned good stored in a garage. Obv it is damp in the air and while sorting the storage out today I noticed some rust on some of the cans.
I know you aren't meant to eat cans that are badly dented, damaged, bulging etc.
Just wondering if this rust is going to cause a problem? I guess over 5 years it would rust thru and contaminate the food?
Any ideas for solutions?
Don't think I can reduce the damp that much. Was thinking about soaking a towel in vegetable oil - then wiping each can lightly before storage. Seems a big pain, and will make them sticky and what not. Hmmmmmmmm
Remove labels, (write contents on the side with a sharpie pen), cover whole can with a thin layer of a varnish. This will protect the can from corrosion. This is already used (in the factory) on the very thin-walled drinks cans as corrosion would eat through them very quickly, not sure if food cans are coated or not. Joe90 might be able to tell you (he is a food-canning engineer, right ?, I'm just in drinks canning )
Handle the varnished cans carefully the varnish will scratch easily and corrosion will appear along the line of any scratches.
It is a bit of a faff, and you'll need to find a suitable varnish, but if you've spent hundreds of pounds on tinned food, it might be worth spending a few quid on some varnish tbh.
i would like to bury twenty or more cans as a stash and wondered if dipping in varnish is going to have an effect on the seam of the tins as they'll experience a lot of solvent ? i,m asking this as i look at several tins that seem to have multiple layers at/along the weld point !?

i`d rather not take a chance , just bin them and replace as and when you can afford to .
it might seem a bit drastic but its the only way to be sure what you have is still safe for every one to eat , not just those with a strong gut .
YES i walked away mid sentence , you were boring me to death and my survival instincts kick in .
if you are boxing them up in plastic boxes try putting some desiccant packs in the box as well to absorb the moisture, Aldi has it from time to time and most caravan dealers they call it dehumidifier packs or some such.
