excerpt from my stupid LCD article that is taking forever to publish:
For ordinary LCD panels that do not have an additional glass bezel, distilled water is still one of the best cleaners. However, great care needs to be taken to ensure that the right amount of pressure is applied to the screen when cleaning. Too much pressure will crack the substrate. This editor recommends using a little bit of vinegar mixed with water on a lint free cloth to clean the monitor surface.
Using a paper towel will leave small abbrassions in the anti glare coating and bezel. Always apply the cleaning solution to the cloth first. Finally, wipe the cloth from corner to corner, and then side to side starting from the top to bottom. This will leave the most even surface.
