There are a few ways to clean glass that gives much better results than those sprays you can buy at the store.
For windows, I really like the effect of the following.
using hot water and a small amount of ammonia, soak a clean rag in the solution and wipe over the offending window, do one window at a time, dont try to "mass clean".
while that is still wet, take CHROME POLISH..yes, you read that right. put a small amount on a rag and rub that over the window that has the ammonia water on it. Once it dries to a haze, rub it off using newspaper that you have crumpled. I have gotten results that make the window appear so clear, its like no glass is there.
[all tips require caution and elbow grease]
now mirrors.
no matter what, the mirror has streaks and haze. but, brew some regular tea [lipton or what you like] the tannin in the tea will do the cleaning for you. brew some nice medium strong tea and into another spritz bottle, [dont use the one you use for ammonia cleaning] spray the glass lightly then rub off using lint free rag or newspaper [the old the newspaper the better]
you will find that there will be no residual haze or smearing and the tea wont hurt the mirror at all.
