I write the name of all of my surfaces and areas in my house down on index cards (counters, floors, chest of drawers, desk, coffee table, etc.) and then every couple of days I pull a card. Whatever card I pull that is the area I clean in detail. Because its a small area it only takes me 20-30 minutes and I can give it attention and get it done right.
What a wonderful idea! I love systems that seem to make work fun. Keep those ideas coming.
