All our but one of our projection port glass is white glass which cleans easily with whatever is convenient. There is one about 20 inches square that is a Neumade coated port. Lens cleaning fluids, glass cleaners, all bead on it like water on a freshly waxed car. Attempts at cleaning do nothing more than reorient the dirt, smears. Suggestions?

I've had that same problem so many times with Starphire, but with coated glass it shouldn't be too difficult. Anyway I reccommend that you get some Industrial Foaming type Windex glass cleaner at a janitorial supply place. That has always worked good for me. If that doesn't work then it may be easier to just buy new glass, some glass just does not clean easily.
