Vinegary smell of the scales, cracks that you cannot relate to any damage. Perfectly dry blade starts to rust.

Are you a bit of a girl?:D

On a more seriuws note: a dry towel is really all you need if you keep the scales and pivot area dry.

Apparently you're not the only one with this problem as I have seen this on many blades I bought on ebay.
All the above advice is very sound, you see there's many ways to look after your razors....
