Spot clean. You won’t have time to scrub the baseboards, but you can fake a clean house pretty easily. Stow clutter where it belongs (or shove it into a closet), wipe kitchen and bath surfaces, damp-mop floors and run a dustcloth over furniture. Dim the lights or break out a few candles — low light is forgiving. And don’t forget that as soon as you have more than three people in your house, no one will notice whether you remembered to polish the chandelier crystals.More: See what you can do when you have a whole week to prep!
