It is more hassle than what it worth. I have a G Claron that has the same thing. I took it apart and put the lens elements in formaldehyde. Did not do a thing, and putting it back together was more hassle than what is was worth. Try using it, if the print comes out nice and crisp, forget about it. If you get image degradation, send it for cleanning.
