No one has mentioned dealing with fingermarks on woodwork yet.... or stairs.... grubby kitchen cabinet fronts... or windows either! :~)
I did, I did! " Spots and spills get cleaned as soon as they are noticed.
I forgot to mention that because I need to be able to open my sliding windows completely for access to water window boxes in summer and feed birds on the window boxes in winter, I remove one pane of glass in the spring and replace it in the fall, when I remove the screen. So twice a year, While I have all four panes of glass out from each window frame, (20 panes in total), I wash them.
