I have these bushnell 12x50 binos on 2 of the lenses I can see this oily looking residue . It doesnt cover the whole lens but you can see spots of it . I want to know of any of you know why it is there I usually clean my binos with a tissue , and water . Let me know if you know away to get he oily stuff off. Thanks in advance .
