I've taken apart my flatbed scanner so that I can access both sides of the glass for cleaning. I have a microfibre cloth ready. What fluid should I use to spray onto the cloth for cleaning the glass? I understand that Windex is not to be used. I have a bottle of Nexxtech Anti-Static Cleaning Gel (it's not really gel, it's just as fluid as water) that says it's for Plasma and LCD screens. The fluid is simply a bit of Sodium Lauryl Sulfate in water. Is this OK to clean the scanner glass with? I just tested it by cleaning a cheap magnifying glass I have. There appear to be no streaks or spots.
