I have notice on the chrome around my car it is holding water spots. I have washed they are still there. What is the best way to get rid of these hard water spots ?

I live in CT now and I don't see this problem. However in Colorado it was a big problem on the 'black' chrome. The trick was to use carnuba wax on the trim. It cleans up the spots and prevents them. You want to avoid using too much polish because that will eventually remove the 'black' chrome.
