I don't mind the cleaning of most things - I dislike doing the windows. There is 4 sides to do on every window here, because of the cold. I'd gladly pay someone for it.

Clean them in a warm season then :)

I mean, because of the ways the windows are made, they take ages to clean. For our place, it is probably a day and a half of work :D

I know, windows is a real trouble for cleaning. If any streaks left, you should clean again :)
