Outdoor metal furniture requires routine cleaning and maintenance to keep it in good shape. Dirt, grime and other forms of debris make the outdoor furniture grungy and unsightly. Ultraviolet waves and harsh weather conditions cause even more serious problems, such as faded and chipped paint, oxidation and rust. Restoring and refinishing outdoor metal furniture is much more economical than replacing the furniture. The important thing is to clean and repair the furniture before the damage becomes too severe.
