How do you clean your glass negative holders, and without ensuing drying streaks? I have tried 90% medical rubbing alchohl, and now the glass is worse that before before it tried to clean it.
Lens cleaning fluid and cotton balls work wonderfully on the glass carrier for my Nikon film scanner. I assume that would work fine for glass enlarger carriers as well. I never used glass carriers in my darkroom, the plain ones on my Beseler 23cII worked fine at keeping film flat. My scanner, on the other hand, has crappy carriers so glass is required for decent sharpness. Kinda miss the darkroom
I have been using the Kinetronics Digital Scanner Glass Cleaning Kit to clean the glass holder of my scanner. Even with meticulous cleaning (at least by my standards), I still get some dust. I also use anti-static gloves to handle the holder and the film.
The microfiber cloth works well; also consider denatured alcohol which you can get at hardware or home-improvement stores. It's ethanol with enough methanol to keep it from being drinkable; leaves far less residue than isopropyl, which is what medical rubbing alcohol is.
Thanks to everyone for your fine suggestions, I tried eye-glass cleaning solution and it seems to work, albeit reasonably well.
Now if I could only find a solution for my darkroom dust problem, and for which I have tried all the classic remedies. At dust prone times like this, the high huminity and heat of the summer - with very little dust - does not seem so bad.
For my contact printing glass I use Stoner Invisible Glass cleaner. You can find it in the automotive section in Target or other stores. Seems to work well.
