I picked up a razor that was in fairly good shape. The scales where slightly off. I straightened them out. That was cool.

The blade has a couple of stains and pinpoint rust spots. What's the best way for me to remove them but still maintain the etching on the blade. Can I just polish it out with a metal polish? I have other blades but this is the only one that had shown any rust since I have gotten them. Are some blade more prone to rusting? How can I help prevent that?

Thanks,
