I purchased a stainless steel razor and 10 shaves in I am noticing rust around the pin.

I know that you are not supposed to douse the whole razor in the water and I do not. I think that when I rinse the business end of the blade off the water that splashes onto my fingers in turn runs down into the hinge.

I am guess I need to start using a sponge to wipe off lather?

How long can I wait before sending the blade in to get the rust removed?

What would that process consist of? Sanding off the rust and buffing the steel?

Thanks!
