I'd not thought of cooking oil. Might work. Thanks.

I use some oily stuff called De-Solv-It but I've heard that any kind of oil based such as WD-40, olive oil, Goo Gone, will work.
My WD-40 is in the garage, but my desolvit and olive oil are in the kitchen where I'm usually doing that :-)
I've also used hair dryer heat for some label removing projects so that the glue comes off with the label.
And I buy my salted roasted Spanish peanuts in bulk now that I discovered them at my nearby produce store, so I don't get any more cans with them. Being a can saver, I just pour my bulk peanuts into the old cans with plastic lids.
