These types of wood resist decay very well, but still must be maintained. The reason is that the dirt that accumulates on the stand can itself mildew and needs to be sanded off. Lightly sand the wood to remove the dirt every year and apply boiled linseed oil (easily found at most hardware store). This simple process will allow you to enjoy your furniture for years.
To maintain the beauty of your furniture, clean it regularly with soap and water. Use nonabrasive soaps. Do not place flowerpots or any items on furniture that could leave stains. Avoid placing excessively hot items directly onto furniture to avoid melting. All hardware is stainless steel and virtually maintenance free under normal conditions. In coastal areas, hardware will need regular rinsing with fresh water to eliminate rusting. If you properly care for it, you'll be relaxing in your fine piece of Poly Lumber furniture for many years!
