Also, sometimes the windows come out a bit streaky. I've tried cleaning some of the windows with a lens tissue after I use the Webril Wipe to get it as spotless as possible, but you can still see some *slight* streaking. I know that ideally you are not supposed to see any of the picture on the port glass, but in reality is this ever going to happen?

Are Kim Wipes OK to use as lens tissue? Until this theater, that's what I've always used. I am currently taking a soldering class and we use Kim Wipes to clean the flux residue off the boards. The instructor said they have fiberglass in them, which raised a red flag in my head. I've never known them to damage a lens, but I just wnated to make sure. thx.

I don't know if those windows were coated. I think they were the Kelmar windows. They were on a hinge and you could easily get to the other side without having to trek up a ladder.

If anybody knows the real name of this product I've described, please post it here...I'd like to order some of it.

Get yourself lens cleaner, McDonald's napkins and a small 2x4 inch sanding block from a hardware store. Using 3-4 napkins at a time, wrap them on the sanding side of the block and douse the napkins fairly generously with lens cleaner. Wipe the inside of the glass with medium pressure (nothing strenuous) in a vertical motion. Then IMMEDIATELY take a few more napkins and lay them on the sanding block and press HARD on the glass to wipe it dry, again using vertical strokes. Repeat this procedure for the auditorium side, but wipe this one in a horizintal fashion. Then turn on the projector and xenon with no film in the projector and take a look at your glass. If you see any vertical streaks, they are on the inside of the glass and you can generally touch them up with a dry napkin. If the streaks are horizontal, they are on the outside of the glass and again you can generally fix it with a dry napkin.
There's just something about those McDonald's napkins that works wonders on optical glass. However you must have the sanding block to do a good job. Don't try and use other kinds of napkins, as McDonald's has the only good ones for this job. The lens cleaner will get off that baked on cheap glass cleaner residue. When you are done, you will not be able to tell there is glass in the window frame.

BTW, could you tell me who manufactures the Webril Wipes. I will have our buyer try to get some. The MikeyD's near the theatre really don't like to see me!! :-)

For the collectors/reflectors I just tried Simichrome today and it's amazing!

My new tech turned me on to it. We were able to find it at the local motorcycle enthusiast shop. It's a paste and it comes in a tube.

It says that it is for metal products, so I don't think I'll be using it on glass (although it might work just fine).
