First of all, thanks so much for your informative reply, among the things you mentioned..I really feel like this is one of the most important: "When you clean the screen be sure to buff out the streaks...you'll need the dish soap first and then another damp lint free cloth or paper towel". The last time I cleaned my screen, its just what I used to do so. I guess the first time that tried cleaning the screen I didn't do so properly,that's when I noticed the haze on the screen, and even though I don't recall using anything that was harmful to it (I did a lot of research before I performed the procedure), there was a hazy look that was left behind. After I used the distilled water with a small amount of dish detergent in it and then carefully rinsing the screen with distilled water and drying it with a microfiber cloth, it seems to be quite a bit better. I think another key point that probably might need to be mentioned would be to thoroughly dust the screen before attempting to actually clean it.Please Stay Safe !!
