I wouldn't mind washing windows if they looked good when I was done.

3. My secret is crumpled newspaper also.

It doesn't seem to matter what I use as the cleaning solution, if I don't use newspaper to dry and buff the windows, they are streaked. I have finally settled on using ammonia for windows because, like you, I don't do them often and they are pretty dirty and greasy by the time I wash them, and ammonia is one of the few things that cuts all the grease.

I also learned this years ago when I had a whole bank of windows and sliding glass doors: for the outside windows that this is possible to do, just use a sponge with a bucket of water with dishwashing liquid and wash down the windows, then just hose it all down. The windows sparkle and no streaks. Too bad it can't be used inside! But at least it does make the job one half easier on those windows.

I feel for you with the small panes and mullions. I have one door with windows like that, and it is a lot of work---especially all the corners you have to deal with.
