One day, one room: Dedicate half an hour to cleaning one room every day instead of cleaning the whole house on the weekend.
My husband and I still subscribe to this policy. In addition to picking up after ourselves throughout the day, we set aside 15 to 30 minutes for more intensive cleaning tasks like vacuuming, scrubbing toilets, and sweeping and mopping floors. Mondays we deep clean the dining room and kitchen, Tuesdays are foyer and living room, Wednesdays are bathrooms, Thursdays are bedroom, and Fridays are our shared office. We have created playlists that are 15 to 30 minutes long on our iPods with collections of fun songs to listen to while we clean. So, when the music stops, our cleaning tasks are usually coming to a close.
