Hi, noticed that I have quite a bit of dust in and on the lens of my Panny AE700 projector. Anyone any tips on cleaning it, the dust outside the lens is my own fault for not replacing the cover after every use, laziness I know but it's ceiling mounted so I have an excuse. However there is quite a bit of dust showing inside the lens as well and was wondering how to remove it. Any help/tips gratefully received. Mike.
