Chrome is extremely hard, extremely thin, and clear. Think of it as a clearcoat for the nickel plating beneath. As said on some of the posts above, rubbing your chrome with an abrasive product will only serve to eventually micro-scratch and dull it, then remove the clear chrome finish, revealing the nickel, and eventually copper coating beneath it. If your polishing pad or cloth is turning black, you have worn the actual chrome off, and you are "polishing" the nickel plating, which will be temporary, until it tarnishes again.

That said, you really can't "polish" chrome, but you can protect it. I use Turtle Wax paste, as it has no abrasives. Rub a thin layer on, let it dry, then buff it off with a clean micro cloth. Any good, carnuba type wax with no abrasives will do.
I've heard that the chrome plating itself is clear in other threads here. I'm not saying that it's not true, but can you provide any sources that explain that in detail? I'm really curious about it. I did an internet search and can't find anything that explains the clear coating.

I agree. This is the first time that I'm hearing of any metallic plating being clear. I hope they're not trying to normalize us to clear coat as being the finish "plating". BS on that.

I agree, it's hard to find information on the ultra thin Chromium coating . After much (1.5 hours) searching, I found THIS:


See : Decorative Chrome Plating.

I believe a lot of the confusion lies in the fact that the solid element "Chromium" is silver/gray in color, with a Blueish tint. Once it is mixed with acids and heated, and the fact that the actual chromium layer over the Nickel is so thin, it is transparent.

Yes, this explains it quite well. Thanks for all the time you spent searching!

I'll just quote the part that applies to my question:

"Decorative chrome plating is also referred to as nickel-chrome plating. It involves first electroplating nickel on the part before plating it with chrome. Sometimes, copper is electroplated instead of nickel. The nickel or copper level provides smoothness, corrosion resistance and reflectivity. The chrome layer that is added is very thin and is measured in millionths of an inch.

The effects that you see when you look at a nickel-chrome plated surface, you are primarily seeing the nickel plating. The thin chrome layer adds a slightly bluish hue, protects it against tarnishing and scratching and helps to add to the corrosion resistance."
 
Some things are just nickel plated, but it doesn't look good very long without the chome layerover it. A quality chrome plated item is copper plated--sanded, nickel plated, and chrome plated. Higher end jobs may get recoated with copper and sanded several times to get it perfect.
 
I think what contributes to the misunderstanding is that many METAL polishes market themselves as metal and also chrome "polish", which is incorrect, as folks should NOT be trying to polish chrome, just protecting it with some sort of non abrasive wax.

If you really want nice chrome, just rinse it off with a hose thoroughly, wash it with mild soap and water, dry it, soak a small micro cloth with rubbing alcohol, apply the alcohol, let it dry, then buff it with a fresh micro cloth, and then wax it. It will shine like a mirror!!
