Furniture made of aluminium is on the whole free of maintenance. Clean it with water and a soft brush. In case the furniture is very soiled, you can wash it with a hand washing-up liquid.
For all furniture in aluminium or with aluminium frame it is important that you do not flush it with a high-pressure cleaner as the hard effect from the high water pressure will spoil the surface of the furniture.
