I am in Sterling Ranch, south of 470. My 911 was used at your facility north of Denver but I am probably closer to your Centennial location. I will get some of the iron remover, I still have lots of stuff left from the large bucket of stuff I bought at the demo but iron remover was not one of the items. I even used SOS (lightly) with no effect....it has to be something chemical that will leach out the stains. The fact they are orange-ish in color makes me think iron or some sort of chemical intrusion on the chrome. If I do manage to get this out what kind of polish or sealer should I consider to apply afterwards?
