Chemical Rust Remover

[ElvisC]

I recently bought a box lot of razors and wanted to clean them,,, Some had rust, so I purchased a chemical rust remover - Krud Kutter. It did a good job removing the rust and gunk but unfortunately, it also removed the luster from the blades. Now the portion of the blade that was in the solution has a matte finish. There is a distinct line between the matte "cleaned" part and the shiny "uncleaned" part.

Is there a polish that will bring luster back to the blade? If not, will time on a sharpening stone or wheel bring them back? Or . . . have I simply ruined the blades?

Thanks for your help.
