Hello new poster here so go easy on me ;) I was browsing the forums and saw that a user had pictured his set (may have been a CL13) with the bulb out and mentioned it was a good idea to clean the lens. So i decided to do this, but in my case there's dust on the inside of the lens :( , is this affecting my IQ at all?

Here's a pic:
