Brown spot on razor

I take better car of my razors than I do myself, it seems like. So tonight when I was shaving I noticed a little brown creeping in near the heel of my blade. My heart sunk a little bit when I saw it... I really hope its not rust but I'm guessing it is. I'm going to post the best pic of the culprit I can manage to take and hopefully you guys can give me some good news! It was a really great shave though! In case you were wondering :)

Right on the end there just above the heel I hope you guys can see it....

Try some Blue Magic on it. Might just wipe off...also check

your center pin. Make sure that is okay!

If it is a 3pin scale.

A toothpick with some Maas or Flitz polishing compound will get that right off.
