Rust spots

I don't think Hoppes No.9 would be around for nearly a hundred years if it removed bluing. I can believe it might stain or have some effect on cold bluing (Birchwood Casey or Brownells Oxpho Blue), but not cold rust bluing, hot bluing, or nitre bluing.

Just got a new bunch of Frontier pads. They're selling a new lube/cleaner/protectant called Safari Charlie so I ordered a bottle. Just tried it on a 1 frame 16 project and it did a good job. I still use WD-40 when I'm serious with the rust. Safari Charlie cuts the hardened gunk right out of screw slots but haven't used it long enough to see it's full potential.
