Window cleaning: Clean narrow cracks
The window frame contains at least at the lower edge of a very narrow gap / gap in which also deposits dust, especially if the window is often tilted open. This I clean with a damp thin cloth, which is wrapped around the narrowest possible (tea) spoon end: It is wonderful in these columns and the moisture wipes everything on the same.
I use a moistened Q-tip for the real corners, which are not actually to be "reached" (I hear some people again because of the "waste", but I do not care).
