Mark my words!
I'll probably regret saying this some day, but I'm looking forward to plain-old house cleaning. The cleaning up of sawdust, construction mess and nails from the floor gets a bit old. So the other day I washed all the upstairs windows, knowing that they'll be covered in dust fairly soon. Thanks Dad for teaching me how to clean windows so they look like they're not even there! I use a simple solution of water with a few drops of liquid dish soap in a spray bottle. I spray it on the window and then use a window strip washer to then scrub the window.
This is followed by the squeegee which I wipe off each time I use it. You do need a good squeegee with rubber, not hard plastic, otherwise it won't work very well.
For the larger windows, it helps to spray and scrub the entire window, then squeegee. I keep forgetting this and I end up spraying the side of the window that I just cleaned. When I clean the inside of the windows I put an old towel along the windowsill to catch the drips. This works great and if you're careful, there aren't any streaks. Much cheaper and less messy than window cleaner and paper towels or newspaper! If you have smaller windows, make sure you get the right size of squeegee so it fits.
I considered washing the downstairs windows, but as long as the chopsaw and half the shop are relocated to the living room, I don't think there's much point in trying to keep those clean.
