Thanks for the tips. It sounds a bit drastic to use any sort of abrasive on my beloved Ultravids (must admit it had already crossed my mind). I might try zuiko's suggestion using a very weak solution of sodium bicarb. on a small area.
I am also thinking of contacting Leica directly to see what they say.
It seems to me that the armouring is made from some "old fashioned" type of rubber rather than a modern synthetic-based product. I wonder if the material will decay (perish) with age?
