Aluminum is strong, non-rusting, low maintenance and very resistant to the weather. Apply a coat of non-hazing automotive paste wax at the start of each season as well as before putting your furniture away at the end of the season. Use only mild soap and water solution, rinse and dry thoroughly. Do not clean the furniture with abrasive pads, brushes or cleaners. Store indoors or leave outdoors and protect with furniture covers during non-use seasons.
