Best way to deal with surface rust?

[MikeP150]

As the title says, I have an old shotgun with some light surface rust issues. What's everyone's go to for cleaning this up?
Cheers!

Flood the surface with WD-40 and wipe down with 0000 steel wool.

Personally, I would use 0000 bronze wool with gun oil.
