So....do you have a rusty chrome bumper?
 

This trick will remove rust from any chrome.

I just found this out on another site. I wanted a cheap way to remove a little rust spot from my truck's bumper.

You get a piece of aluminum foil and dip it into some Coca Cola. Rub the shiny side on the rusty spot. It melts the rust right off. I couldn't belive how quick it works.

So if you have any rusty chrome, give it a try!
