Can you remove rust spots on a blued finish with wire wool without removing the blue?

I've always had great results with Flitz polish. It doesn't affect the blueing but takes cares of the rust. Leaves protective finish is a plus.

I used this on my COLT blackpowder pistol once took the case hardening right off, and on the bluing my rag was blue in color?

ALWAYS test Flitz on a non-visible surface before diving in full-bore.

For most modern chemical blueing it is harmless, but it will instantly dissolve old-time rust blueing. If you aren’t sure what you’ve got, be careful with it.

I think the stuff Flint45 pictured is sometimes known as Frontier Big 45 (only available in the US)...I've used the stuff and it's brilliant, looks aggressive but if used with oil I've found leaves the blue unmarked.

I've used the copper coin trick for donkeys years too, not sure where I heard it from either.
