[DRH]

Don't give up on your clouded window quite yet. The clouding could be caused by moisture that was trapped when you stored the window with part of it folded onto itself for a couple days. Try laying the window out in direct sunlight on a dry day for a few hours and see what happens. Make sure air can circulate on both sides of the clear vinyl. The sun may bake the moisture out of the vinyl, and the window might clear on its own. Worth a try.
