Ugh. Your guests arrive in 10 minutes, and the house is a disaster area. What's more: you haven't dusted in weeks. Don't sweat it. Speed clean. Turn down the overhead lights and spark up a few candles: the less illumination, the better. Always have convenient, hidden space to shove the clutter temporarily (a closet works just fine). Now, dust only the areas visible to your tallest friend. Voila! Instant clean.
