Haze on plastic windows is, more often than not, caused by nothing more than using paper towels to clean them. Paper towels are made from pulverized wood products and they leave tiny scratches every time they are used. Eventually, paper towels leave a haze on plastic windows that ultimately turns them opaque or yellow.
When windows are dirty, the only thing you can safely use on them are soft fabrics like old soft cotton towels, cloth diapers, t-shirts, etc. Rinse the dirt off first, then use soap and water. Only wipe them when the dirt is rinsed off.
To get scratches out, use a multi-step plastic window polish that starts off coarse for scratches and ends up with a very fine polish to return the sparkle to them. Meguiars and Novus are two good brands of multi-step kits. Lots of work to get scratches and haze out, it's better to avoid things that scratch them... like paper towels, laying them on top of each other when dirty, etc.
