Ezio, I have seen quite a few lenses with fungus which was on outer surfaces and could not be removed by usual lens cleaning fluid which mostly consist of tensides and/or mild solvents such as alcohol. For some reasons most species of fungus seem to be resistant to these, even to lighter fluid, but vinegar usually removes the fungus if it has not grown for too long time. |
