I went on another of my lunchtime razor hunting trips and found so real choice pieces, i.e, Dubl Ducks, Henckels, to name a couple. However I’m concerned. One or more of them have patches of fine powdery orange-red rust. My first thought was cell rot, and so I did not purchase any as I wanted read up on what exactly celluloid rot is. From what I can find here though is that cell rot usually occurs on the part of the blade that rests between the scales when the razor is closed. Well these razors had this powdery rust on the spine, or outside of the scales, or failed to be relative to the scales in some other way. Now I have two questions before I go back to get these:

1. Could this fine powdery orange-red rust be cell rot even though it appears independent of the scales?

2. If celluloid rot, can you rescale a blade that has had rust from cell rot, and halt the decay? That is, if you junk the guilty scales, clean up the blade, and throw some brand new wood, horn, or acrylic scales on it, are you safe from the celluloid rot and subsequent rust? Or once touched by celluloid rot, is a blade doomed forever?

As always, thank you all for any help.
