As a durable and beautiful choice, a teak outdoor dining set can provide years of quality enjoyment. Because of the natural resins in teak wood, it is not subject to drying out like many other woods. The silica within the wood composite helps keep it from molding, rotting or shrinking. To clean teak patio furniture, simply brush gently with a mild solution of soapy water, then rinse. A wood cleaner can be used, as well.
