I think this is the case. My shoes are new, and the only thing was black rubber nothing more. The "stain" is lighter color then the lid, so I think it's the lid.

You should at least try my method. What do you have to lose?

It's hard to believe that you scratched the aluminum with your shoe unless you really kicked it hard or had a rock in the sole of your shoe that scratched the metal. Good luck.
 
Why not try a damp microfiber cloth? I've had great success in cleaning all sorts of gear with microfiber cloths. First, dust off the area, dampen the cloth, and rub back and forth over the scuff. Shouldn't take more than a couple of minutes to clean it. And it's less abrasive than a Magic Eraser.
 
One last thing to try that won't hurt the finish even if it doesn't work. Take a clean soft absorbent cotton towel or a micro polishing cloth. Make sure there is no dirt or residue on the cloth. Put a dab of baby oil, (or any light oil like you would use to lube the blades of an electric razor) onto the cloth. In a pinch, vegetable oil might work too. Rub the stain in a circular fashion until it is lifted. Be careful to have just a thin coat of oil and not get it anywhere but on the stain. After the stain is gone, you can remove the oil residue with a solution of water mixed with a bit of isopropyl alcohol, or monitor cleaning wipes.

I have used this method to remove a lot of tough stains. It works by penetrating the substance so that it can no longer stick to the surface it's bonded to.

If this doesn't work, I think you have scratched the surface and the stain is embedded in the substrate.



Ok what about like skin so soft? That **** takes paint of your hands! lol
I'll try the lighter fluid thing but VERY lightly.

It's hard to believe my shoe did this but it did. It's a Puma and the rubber rides all the way up the back of the shoe. I' m telling you guys, it wasn't a hard hit, I guess maybe just hard enough? I don't know, you really cant see it unless under the right lighting, I really do think it's the case, and not some sort of dirt, I mean come on Mr. Clean didn't work!


Thank all of you though, for taking the time out of your day to help me out. I'll try some of the other ways of doing it. I'm afraid to make things worse though.
