A good portion of my camera domes get invaded by spider webs and such. Being new to this field I was curious as to the best approach in dealing with this problem. What is the recommended cleaner or cleaning method, as to not scratch the domes? Also I was thinking I could spray some bud spray up and around the housing, at least it seems like a good idea for now. Last question, some of my camera domes have been spray painted or had bumper stickers placed on them. Any ideas on how to remove this stuff without damaging the domes?
