Caring for your arbor depends on several factors, including the construction material, environmental conditions it withstands and its type of coating. The structure manufacturer should have care instructions available for your chosen structure. For Arbors Direct fiberglass arbors and pergolas, we do provide recommended care and maintenance instructions with every complete pergola and arbor purchase.  We recommend treating your fiberglass outdoor living structure as you would a cherished automobile.  Never use harsh or abrasive chemicals or cleaning materials and use low pressure water to clean the structure.  For more information, please view the Arbors Direct Recommended Care and Maintenance Guidelines.
