It is essential that exposed aluminium surfaces are washed in clean water 3-4 times a year, more in marine or industrial atmospheres subject to excessive dust and airborne particles.
Exposed powder coated or anodised surfaces need to be washed with a warm water solution of mild detergent at intervals of not more than three months (1 month in high pollution areas), using a soft cloth, sponge or natural bristle brush.
In cases of heavy soiling of the coating nothing harsher than white spirit should be used for cleaning and under no circumstances, abrasive cleaners, or those containing ketones, esters, acids, alkali or alcohol, however well diluted.
