Hi, I am new to straights and have meticulously dried my razor after every use. I blow on the scales to remove any water. I dry the blade on a towel. And then strop on linen 25X.

Today I noticed a tiny bit of rust between the scales where the pin is. I moved the blade in every direction and removed as much as I could. There is still some left.

How can I remove this rust without removing pin? How can I prevent this from happening again? Is this even a big deal?

Thanks for any advice.
