These included cleaning the windows. Since I am proud to be a trained window cleaning professional, here follows a short thread on how to clean windows quickly and well. (1/n)
An old towel or rag
Sponge
A "scrim" cloth. A baby muslin or worn linen dish towel will do fine as this.
A bucket helps a lot (2/n)
Use water with a bit of washing-up liquid and an optional splash of vinegar. Soap up one window with the sponge, scrubbing as necessary.
Then use the squeegee to scrape the water off. (3/n)
Wipe away excess water with towel.
Polish round edges of window, and any remaining smears, with scrim. (4/n)
Ladder technique is a whole other chapter, unfortunately, and my advice is not to clean anything you can't safely get to. (5/n)
