Aluminium furniture whether it be extruded, wrought or cast, has the advantages of being lightweight and rust-proof and can be left out in the garden all-year long. Simple cleaning with a soapy cloth or sponge is all the maintenance required. Although it has sizable longevity, wrought iron furniture should be brought indoors during the winter, or at least covered, as it is prone to rust particularly in coastal areas where sea spray or salt air will have an adverse affect. Some simple touching up will be required from time to time. A liquid wax polish can be applied to prevent rusting.
