OK, I know that the Mythbusters didn't invent this idea, but that's where I heard about it.

Step 1: Have some rusty chrome.

I'm sad to say that I've been a bad daddy to my little bike. These pipes were new a few years ago. The originals were completely rotted out, so I got these replacements on e-bay. Par for the course with aftermarkets the chrome ain't that thick.

It doesn't help that I haven't so much as pulled the cover off for weeks at a time.

Step 2: Supplies!

You will need:

"Cola" - I used Wal-Mart diet cola. I'd heard that diet is less sticky. 54 cents for 2L.
Aluminum foil
warm water
paper towels

Step 3: Pour 'n Scrub

Pour the Diet Coke on your rusty chrome (is there any better use for this stuff, lacking Mentos?) Crumple up some foil and use it to scrub the nasty rust away.

Rinse with warm water and wipe dry.

Step 4: Gawp at the Results.

I was really blown away. In some of the pictures the flash makes it look more scratchy than it really is. I don't think I'd use this on a top dollar bike, but I hope a top dollar bike would have better chrome (and better care).

To protect the restored shiny chrome carefully spray with your favorite lubricating oil spray and then polish with an old cloth. This leaves a protective film on the metal which repels water. This is good for cleaning, polishing and protecting
and only takes a few moments effort every time you clean the motorcycle
to keep it looking good.
Aside from a little elbow grease what makes this method better than chrome polish ?

The phosphoric acid in the cola is what does the trick. I have used regular cola without the foil on engine parts. The sugar helps hold the phosphoric acid onto the parts while soaking. After seeing what cola can do to rust you may want to try www.instructables.com/id/Homemade-Carbonated-Beverages/

I used to work for a company called PinWall cycles. We just used the extremely fine steel wool I always told them they were putting fine scrathes into the metal, but they didnt listen. this sounds better, I'll keep it in mind.

Aluminum foil probably gives an electrolytic effect like it does on slver, removing the rust without the need for rubbing.
