A guy who worked here while earning his chemical engineering degree now works for the state dept. of environmental quality says that most of the dark/black dust that is difficult to remove is probably tire dust if you're in a city location.

After "deep-cleaning" with the sandpaper, use Bon-Ami to polish the lens. Those who ran arc lamps with silver-backed reflectors will remember how well that stuff worked.

I still remember the warning labels, telephone messages and large-lettered postings in the booth about changing cleaning habits when our first front-coated dichroic arrived! [Eek!]

i made a funny discovery today when cleaning our scope lens (that had been running alien vs predator 2 last night) I found a rather lifeless spider sprawled on the front of the lens. I wonder if he decided he'd camp there for the night. Took a long time for me to remove it fully as it was rather 'burnt on'. I guess he had crawled onto it during last nights show....

cant imagine what the audience thought.

We use Roscoe lens cleaning tissues and Lens Cleaning fluid from Jack Roe (cs) ltd. Guaranteed to remove even the crispiest of critters!
