I just moved to Denver and have noticed that some of my stainless steel cookware, thermoses, and the outside of my crock pot have a very thin layer of what appears to be rust on them. I've not washed them since being here, so I'm ruling out the option of new/different water deposits on the items. It appears to be something in the air, because only the outside/exposed areas of the cookware are effected. I tried wiping one thermos with a wet cloth and the film came off, but thermos still showed signs of "rusting."
I tried to find a topic on this elsewhere but didn't run across anything online or on the board that seemed to explain what's happening. Any and all help or suggestions are appreciated!
