Natural Tarnish Experiment
Just got back from seeing some family at the beach for a week. I stripped these two street brass Zippos and left them at the house stowed up under the deck.
I saw the tarnish on the brass doorknob on this closet outside and I got curious: how long would it take a Zippo to do that?
