I have had to get rid of 3 sets of scales with celluloid rot. I would clean and polish the blade, then the next day or the day after there would be rust along where the scales lay next to the blade. There was also a strange odor. I immediately removed and discarded the scales, cleaned and saved the blades. No further rust appeared. Celluloid rot is contagious, so if you are not sure, quarantine that razor in a separate container from any other celluloid scaled razors, until you are sure. Hope it is not the case!
