I have got a chrome tip on my car. I like to have all parts of my car looking good and clean. This might have been posted before, and many people might do it, but i wax my chrome tip, to keep it looking real clean and shiney. I have tried a liquid wax like eagle 1-wax as you dry, and a paste wax of turtle wax. The paste works better. I dont recommend turtle wax though, it doesnt do good on the rest of the car imo. I will post pictures later, after i get finished washing my car, and waxing the tip.
