If the aluminum furniture is in poor condition, rub each piece briskly with a steel wood pad. Once the metal is smooth again, wash it in a mild detergent and water solution. Rinse and dry thoroughly. Protect the rejuvenated finish with a light application of automobile wax, then buff to remove any excess. Ideally, aluminum should be washed and waxed every few months.
Plastic resin is extremely durable and weather resistant.
It can withstand the elements, the stress of ordinary use, and the extra wear that outdoor furniture endures. In addition, resin furniture can be easily stored because the pieces usually break down or stack to take up less storage space. Or, wipe the surface with a sponge or cloth dipped in a solution of hand dishwashing detergent and warm water. Rinse thoroughly and dry with a clean soft cloth. Redwood furniture is attractive and weather resistant in that it is not likely to rot or warp.
