Lightweight and powder coated specific for the high UV of outdoor environments, aluminium is a great, low-maintenance material. For outdoor aluminium surfaces, we recommend: Dusting regularly using a soft, dry cloth. Avoid using cloths containing dye as the colour may transfer. For thorough cleaning, use natural soap and warm water. Rinse with clean water and wipe dry to avoid streaks or traces of limescale. Avoid letting water rest in retention areas such as joints. Wiping away bird droppings to avoid the risk of corrosion or marks due to the high acidity. Not using steel wool, harsh brushes, pressure washers, mineral acid, bleach or chlorine cleaners on aluminium surfaces. Not dragging furniture along surfaces, as this may cause damage or leave permanent marks on the terrace. All outdoor items are fitted with protective glides; always lift the furniture when moving from place to place.
