What will take sediment and water stain off of windows?
I have a couple of windows at work, that have this cloudy appearance on them. When they are still somewhat wet, just after I clean them, they look good until it drys. The haze and or cloudy appearance is still there. I'm guessing it's from the sprinklers and or whatever is in the water and baking in the sun for twenty years. Does anyone know how I can get this window clean and clear to see through again?
