After cleaning my laptop’s LCD several times with Windex, a fair amount of streaking built up, making the display far less than perfect. A quick search suggested a 50/50 mix of isopropyl alcohol and distilled water was the best solution for safely, and effectively cleaning LCD displays.
After mixing a batch, and tearing up an old cotton T-shirt, I gave it a try. At first pass, the streaking was minimized, but still there. I applied a more generous amount of solution to the cloth and went at it again. After some light rubbing the streaks were gone, and the display is good as new.
