Federico,
The blades on my non-AI Nikkor 50,f1.4 got oily about a decade ago to no
apparent ill effect so I wouldn't worry about it.

Subject: [Leica] Oily marks on lens blades
Hi, guys!
I own a Summicron ('60s vintage) and a Summarit 50mm for my M's.
Recently, on the diaphragm's blades, I realized the presence of some kind
of oily marks. Is that harmful to the optics or more importantly is it
going somehow to be noticed on the images? It seems to me that the lenses
performed great so far. Would it cleaning be a necessary option and would
it be expensive? Thanks for comments and suggestions.
