Well, I got it done-ish. There isn't much info out there on the camera.
The close up lens is moved between the aperture and primary lens with the little lever at the bottom of the lens bezel. It moves across the aperture in a wiping action, like a windshield wiper. I got the back of the lens good, and I was able to get the majority of the back of the closeup lens, it's the front of the closeup lens that is inaccessible. When the closeup lens is in place there's a gap between the two lenses. I tore a piece of cotton from a cotton ball and dampened it pretty good with isopropyl alcohol. Using small tools I stuffed it through the aperture and up against the back of the main lens. Then, using the lever I moved the closeup lens back and forth. The cotton ball stayed in place for the most part, I had to stop and reposition it a few times. It did a fairly effective job of cleaning a good part of the lens, at least enough to take some photos with it and see what happens. I removed the cotton ball and leftover fiber strands with tweezers and canned air, then cleaned the back of the main lens again.
This will have to do until I can get more information on how to remove the shutter assembly. In ay even, the camera can be used with the regular lens no problem.
