Had the same issue, took out the matte/focus screen with the changer tool I have here since I bought the grid screen, cleaned it with the ICK-1 (a blower works almost as well) and reinserted it. It is tougher when the dust is in the prism assembly, so blowing with the screen in place is a bad idea or so I was told (yo unever know how good advice is on the internet these days). But what I can tell you from personal experience is that the Pentax sensor cleaner aka ICK-1 is safe to gently tough the screen with. Cheers Ecke
