While Grosfillex cannot warrant results of any specific cleaning method or product: A mild detergent such as dish soap and water will usually be all you need to clean your furniture. Chairs and chaises without metal parts have been successfully cleaned by soaking them in pool water and wiping them clean. Water with a 10% solution of either bleach or vinegar can remove persistent stains. General non-abrasive household cleaners (e.g., Formula 409, Fantastik, Windex, WD-40) can also help with various stains. For stubborn stains from different origins, such as sap, bird droppings, carbon monoxide and imbedded dirt, try using a resin furniture cleaner such as SunBrite. Mineral spirits, rubbing alcohol and acetone, while generally not recommended, will remove sticky, glue-like or black stains.  Apply the solvent carefully and rinse off immediately.  As with textile home furnishings, every case is different and, depending upon the nature of the staining agent, may require professional attention. IMPORTANT:  Do NOT use bleach or a chlorine-based chemical sanitizer to clean molded melamine tabletops.  Bleach will attack the surface overlay of the melamine tabletop and cause severe discoloration and staining.  Household cleaners like Spic and Span or a mild detergent with water should be used to clean the table top surfaces.
