All, I have a cleaning issue here that I cannot seem to solve. I'm attempting to clean my Nikon CP and am getting a lot of streaking while cleaning it. I've tried microfiber lens cloths and lens tissues with no luck. I'm using a lens cleaning fluid and am spraying the fluid on the tissue and then wiping the polarizer (just as I do with my lenses). I've tried using my breath to fog the glass a bit and then wipe it but have had only slightly better results. So what do you guys do to keep these things clean? I've heard lens pens work ok but thought I'd see what you guys think.
