I don't like waiting for screens to dry/putting wet screens back on spot free windows. When the screen clicks back into its tracks it's always just enough to throw a couple drops on the glass. I just use a damp rag and only take out the screen of the window I'm cleaning and put it back when I'm done.
Putting all the screens back at once was too big of a pain for me..
Which is probably why I sub contract 80% of our residential window cleaning to off duty firefighters here locally at this point.
I don't like washing windows... but it makes us some money and always when PW is slow so I haven't abandoned it completely yet.
