Post a cleaning agenda in each room
Clancy's simple, visual housecleaning tip would work so well for me and my family:
One hack I do that I like is this: I survey a room in my house and figure out all the cleaning tasks that need to be done in that room. Then I make a list of those tasks on a sticky index card and stick it to the wall in that room.
Think how well that would apply for a kid's room! I know my kids look like deer in headlights when I ask them to clean their rooms -- where to begin? Posting a simple list in their rooms -- and in every room -- helps them visualize the task at hand and gives them perspective on everyone's workload.
Oh, and did you know Post-It makes sticky index cards?
