Yesterday at the hardware store I bought a bottle of Windex Outdoor Window Cleaner. It's one of those that you hook up to your hose and just by spraying it cleans the windows on the outside. The price seemed a little steep - about $10 - but it will do all of the windows.
The great news is it works!!! I wasn't expecting much but knowing that I wasn't hauling out ladders this year it was worth a shot. I couldn't believe how well it worked. I did use the hose with the regular noozle to do a final rinse.
The bad news is my arm, neck and shoulder are a little sore. It took me a little while to put the two together - lol. But it is nothing compared to what really washing them would have caused.
And on the bright side this was so easy that I think even a child could do it for you - with supervision. If you can hold the hose you're in!! My only warning is don't try it on a windy day. THis morning was fine but the wind just picked up and the water was going everywhere.
