Thread: Is this rust?

I've just recently started shaving with this Dovo Best 6/8 bought on SRD (my first shave was so cool and the razor so sharp, I can't thank Lynn enough for the service)

However, as seen on the pictures below, there are a few spots that appeared very close to the edge of the razor after my first shave. They clearly were not there before and I was wondering if it was rust.

It hasn't stopped me from having a great shave, but I have noticed the appearance of a couple of more spots. If it is rust, what can I do to remove it?
