The hardest-working parts of the home are often the most neglected. Case in point: the stairs. If you rarely think of yours, now is a good time to take a closer look. Years of trips up and down the steps can wear out the finish on wood treads or turn brightly carpeted stairs dingy. Rent a steam cleaner to freshen dirty carpeted stairs, or sand and refinish worn wooden boards. Also consider repainting the risers, balusters, or railing to give your home a crisp, clean, summery look.
