Ive got about a dozen empty military fuel cans that Im not using right now.  Do you guys store empties open or closed?  Ive got them in a garage thats not climate controlled and Im worried  they might get condensation in them and rust.  Most of them are from the 60s and 70s and they have minor rust in them already and I want to keep them as long as possible.  



I cant put fuel in them as I already store such a large quantity it makes me a little nervous.

MFCs shouldn't rust since they are plastic but a steel jerry can might.  I'd just leave the lid cracked open to evaporate and condensation.

I would probably just buy a refill size can of wd40 and slosh it around in there then dump into the next can and put the lid on. Either that or buy a couple cans of fogging oil.

I keep mine closed when empty.

all my metal cans are full, and plastic is empty.

I would hit each can with some "engine fogging oil" and close them up. I have some NATO cans from WW2 that are fine, and I can't imagine they were full for 70+ years (or climate controlled), so you should be fine.

If it's long term you could always seal them in the winter when there is no/little moisture in the air and recheck each following winter for damage.

I'll have to check out this fogging oil since its been mentioned twice.  I've never heard of it.  Also, the WD40 suggestion was good too.



None of them are perfect inside so Im just trying to keep them from getting worse.

Its definitely going to be long term.  I just cant seem to pass up a deal on these things and they are beginning to accumulate.

I just run into them all the time.  I've never ordered any.  I got these two at the spring Knob Creek machine gun shoot for 5 bucks each.  I walked back in and found two more for the same price.  I dont think I've ever paid more than $15.
