Rust on the board (standoff holes & expansion slot)

Hello folks, now that I have started working on the board again after
a 3-4 months hiatus, its unfortunate to see (quite some) rust on
around/in the standoff holes as well as the expansion slot holes. I
reckon I had left the board in the box in which it came (and
unfortunately I reckon without the anti-static bag to cover it) for a
few months. Although the board's working fine, but I am just a little
concerned about its life & maintenance.

Is there a way to safely remove the rust, or can I leave it as is ?
Also, I hope the life expectancy of the board won't be degraded
much ?

Thanks.

I don’t think it is rust. The plating is immersion silver. That is a normal process that the silver can go through when left in an environment as you desrcibe. It should have no impact on the operation or the life of the board.
