Tin Oil

How do I remove olive oil residue from inside its metal container..?

Any edible oil goes rancid after awhile and smells pretty rotten to boot. Every February I decorate for our singles group's Annual Italian Dinner with as many authentic things as I can find. Included in my decorations are big empty metal tins of olive oil. This year when I pulled out of storage the olive oil cans from last year's decorations, it was evident I should've removed the oil from the cans-last year! Ugh. The smell was very unpleasant...so, do you know of a sure-fire way to rid the remaining bit of oily coating inside the can? Tanks Much!

Water, dish detergent or laundry detergent, shake, rinse. A couple of times. Yeah, the stuff smells but after all, the oil is taken from a living plant and it can deteriorate.

If they are just for decoration purposes it won't matter if they are rinsed out well enough for putting oil back into them.

Sounds like fun!
