Hey all. I've just begun shaving with my Dovo Classic (this guy). I used it yesterday, and this morning discovered dozens of tiny rust stains on the blade, especially around the etching. I dried it carefully after shaving, and let it dry open. My room isn't humid at all, so I don't think the air is a possible source of moisture.

What am I doing wrong? And how can I remove the rust? Some of the rust splotches can be scratched off with my fingernail, but I'm loathe to scrape a razor blade with my nail, since one slip could damage the edge and my finger.
