Thread: Staining/pitting

Hi guys, a bit of a beginners question here I think. Due to a first shave incident a couple months ago involving wet scales, my blade has some stains where it comes in contact with the scales when closed, and a few stains a little bit above the edge. Disappointing to be sure, but I figured they were just cosmetic and so left them. However, I noticed today a darker spot on one of the stains, and I can't tell if it has been worsening and maybe started pitting, or I just somehow looked at it differently (shown in this photo)
So my question is, does this look like pitting, and what can I do about this? I figure this would be caused by moisture in the scales being against the blade, though I dry the scales and oil the blade with mineral oil after every shave. Any other preventative measures, and any way to remove this? I've read that metal polish easily removes gold wash; if I apply the polish carefully with a Q-tip might I get away with it? Or is it still not advisable? (if it is, what kind of metal polish should be used, and how?).
Here are two more photos showing the stain on the other side, and (kind of) the staining above the edge.

Thanks!
