While wandering through the wilderness, I fell in a river. My camera, fell in with me. The camera survived unharmed. Unfortunately the attached lens took in water, and now that it's dry, it is spotty on the inside. I'd rather not have to replace the lens, but after some inspection, I've decided I can't take the lens apart and expect to be able to put it back together. Is there a way to clean it without taking it apart? Maybe some kind of product I can submerge the thing in that won't leave spots behind?
