I pulled my 100 mm f2.8 out and was trying some new ideas about work related macros and found little dots on the front lens. I used "breath" and a micro fiber but couldn't get them off. Must be more than 40 I can see and sprinkled liberally around my lens. The shot shows some of them in the red circles. I ordered Zeiss LIQUID CLEANER and that hasn't arrived yet. I've been known to stick that lens in close but I can't remember what could have caused the spots. None-the-less they're there. Should I send this off to canon to clean or try the zeiss cleaner first? I'm worried about removing the coatings on the lens with the cleaner. The cleaner is from B&H and it was recommended. Any thoughts about having canon cleaning it and secondly, using the zeiss cleaner? I've ordered a B+W 67mm XS-Pro Clear UV Haze with Multi-Resistant Nano Coating in the interim which was recommended on the forums.
Thanks for any input.
