R asked if he could "clean something" one day. So, I grabbed an empty spray bottle, filled it with part water and part vinegar, gave him a roll of paper towels, and let him go to town.
He was a cleaning machine. He washed every window in the house, every mirror, the sinks, the tub, the toilet, the top of the fridge, and the cabinets. THEN, he dusted, Swiffered, vacuumed, and mopped the floors! He cleaned for 2 hours and kept asking for more things to clean.
