I assume you are referring to Leica lenses? If so, have you asked
the Leica Company the same question? Perhaps they have heard of similar
problems and have an answer for you, other than keeping your 
cameras and lenses in a humidity-controlled cabinet. Of course, you
must remove them to make pictures. This could be a prevention,
not a cure. I would like to know what the lens maker recommends.
