I just showed to my son firearms I have, and one of them is CZ 527 Lux in 223. When I took it and touched barrel, I had noticed under finger very slight roughness. Nothing visible, but when I took white cloth, soaked in oil, rubbed barrel, well, it became bit reddish. Obviously, very small rust dots on the surface. I have another rifle and combo gun, but they are smooth, no those rust dots on them.

Any suggestion how to remove those rust dots without damaging bluing? Obviously, this CZ 527 was made from steel that needs extra care. Please suggest a good steel protection that would stick well on the surface. Thanks!
 
#2 pencil lead scrub with the point on the rust spot, and eraser to remove graphite and oxidation. Oil to finish.
 
Use brass or bronze wool and oil, it will not hurt the bluing and will remove all rust. Then a light coat with Breakfree CLP or most any quality gun oil.

Oil or gun solvent to lift the rust up (or pretty much what you have already done). I use a silicon rod-and-reel cloth afterwards, as I want "enough"but not a thick coating.

For corrosion that early/minimal, I'd do exactly what you did: oiled cotton cleaning patch rubbed everywhere til comes away w/o color.
For the "oil" I strongly recommend Hornady 1-Shot Cleaner-Lube (Black can). Leaves only dry film, and is the best/practical rust protection I've ever found.

Thank you Sir for these links and sharing your experience. That rust oil protection test is just unbelievable, I had never seen such methodical and comprehensive evaluation.

I am presently surprised with excellent results from WD40 Specialist. Years back a friend had a small hobby shop and in it one of those small lathes. Before leaving for vacation, in order to protect the lathe, he sprayed it with ordinary WD40. After 4 weeks he came back and found his (brand new) lathe, all unpainted surfaces, especially guides, completly red. And I am not talking about just cosmetic discoloration. He was bitterly disappointed, and since than, he was telling to everybody to avoid WD40 like plague. Unfortunately, many folks don't know real purpose of standard WD40, and mistakenly believe that it is also a good rust protection.
 
Heat the barrel to something like 212 F and pass steam over it. That will turn the rust to rust blue. Wipe it with fine steel wool, then wipe the barrel with an oily cloth while it is still hot.

Then, keep the gun in a low humidity environment.

I've stored my guns at room temperature and humidity for 50 years, during which period they went hunting in cold weather and got condensation on them when they came back inside. I just put them near the wood stove or heat vent until warm and dry, wiped with a slightly oily cloth and put them away. No rust, ever.
 
It's not rocket science use some solvent an extra fine steel wool or even bet the equivalent 3M abrasive pads Then a rag and solvent, then coat with a oil to prevent rust
