Use a soft scrub brush dampened with water and a mild oil-based soap, such as Murphy Oil Soap. Rinse by hosing down.

Care Tip: Untreated teak weathers over time to silver gray, which many people prefer. To maintain the original reddish brown color, use a water-based teak protector, such as the one from Smith & Hawken ($28 for 33 ounces, 800-776-3336, www.smithandhawken.com), at least once a year.
