So I just started using my camera after a few weeks of it sitting in the bag. I went to go do a lens inspection in case i needed to clean it and i saw these little spots with i assume are dried spit. I tried using the lens pen to remove it but no matter how much i try it is still there. Will this damage the lens since it has been on it for a few weeks? And how can I clean it? Also, how much would it cost to get the lens cleaned approximately? There is a lot of dried spit on it and i hope that i haven't wrecked it by cleaning with the lens pen.
