November 2014, downtown Chicago
Performance and supporting documentation
One single pane of a large picture frame window cleaned, from the interior, for an eight-hour work day.
For On A Clear Day, I began cleaning a single window pane at 8:30 am. I cleaned only from the inside. I cleaned the entire pane from top to bottom, and then began again at the top. I used typical window cleaning equipment, including a squeegee on a long handle. I took one fifteen minute break in the morning, one fifteen minute break in the afternoon, and a thirty minute break for lunch. I ended at 5:30 pm, and went home.
