I have a Leupold Scope that has some moisture and smudging inside the eyepiece. I would really like to clean it out. I have had problems with this scope fogging in the past and sent it back to the factory at one point. I want to remove the eyepiece to clean some of the moisture I can see in there, but I'm concerned it might damage the scope. I'm also concerned that if I don't fix it, it could get worse when hunting in the foggy/rainy conditions of SE. Can anybody give any recommendations for how to best clean the area forward of the eyepiece and behind the ocular lock ring?
