I've had my projector for about 3 months now and the lens is covered with dust. I tried to wipe it off with the lens cloth that came with it but when I just barely touched it, it felt rubbery, almost tacky. It felt like if I were to continue wiping it, it would just smear and make things worse.
Does anybody know why it feels like this and why the dust seems to be stuck on there? And how would I go about cleaning it... is this something a lens pen would work on?
