Try distilled water on the cloth (just good and moist, not sopping wet - you don't want to leave behind any drips as you wipe it) and see how that goes. A lot of the streaks and spots on glass after cleaning are residue from particulates in water so you can eliminate that by using distilled. It's cheap, like 50 cents t $1 a gallon at most grocery stores, so worth a try anyways.My screen is really streaked...Can I use glass cleaner (My Dad uses it on standard TVs) on the new iMac since it is supposedly glass?
The new iMac has a sheet of glass over the LCD, so you wouldn't be putting any cleaners on the screen itself, just the piece of glass that covers it.I've been told to NEVER spray a glass cleaner containing ammonia
on a lcd screen. It can discolor it over time.
Commercial screen cleaners are usually a 50/50 mix of distilled water
