go to the automotive section of any store and buy a "automotive" glass
cleaner. THey come under variuos names. They are super window cleaners.

Sometimes buffing with a sheet of newspaper as a final step helps also.

If its a double pane window, make sure the grime is on the outside. THeres
nothing you can do if the dirt is between the two panes of glass.

I am a rather lazy house keeper and have not done my outside windows for
many years. Today, in order to better view the hummingbirds, I tried to
get the grime off of one of the windows. I tried SIX times with Windex
and some of the grime remains. Is there anything stronger than Windex?
