For regular maintenance, hose off the surface periodically and spot clean with a damp cloth. Let air dry.
Avoid using products that will dull the surface, such as ethyl alcohol, abrasive solvents, cleaning powders, steel wool or scouring pads.
To prevent scratches, do not drag objects across the surface of the plastic. Sharp objects can damage the plastic just as they would damage metal or wood.
To prevent fading, keep in a shaded area when not in use.
