Rust removal?

Hi All,

Hopefully a simple quick question:

I pulled my glider out of the trailer after a long winter recently,
and found that I hadn't greased my lift-pins quite well enough. There
are a few small spots of surface corrosion on them, and I'd like to
get rid of it.

BUT, given the importance of the lift pins I don't want to just go
grinding on them. Anyone have any suggestions on the best/least-
destructive way to get rid of minor surface rust/corrosion on parts
like this?

Thanks a bunch,

--Noel
