[Konvas] cleaning mushrooms on lenses ...

[russcine1 at aol.com]

 Nose grease is an old trick for lenses and film gates....Boiling lens elements will destroy the coating. I have a late friend do this to salvage lenses as a very last resort.

A tip? Yes a Q-tip!! I have tested this myself, put oil from your nose on a 
Q-tip and apply it to the intruding "baby", wait a day and clean as normal with 
lens fluid. Found this tip on an antique camera repair forum. 

As far as my test, on one lens it worked perfectly (and I tried cleaning with 
lens cleaner before hand with no luck). On another lens it did not work at all. 
So good luck or should I say "break a lens".
