The natural beauty and lustre of anodising has been proven to stand the test of time. In 20 years, with proper maintenance, your project will look as good as the day you installed it.
Deterioration of the anodised coating can occur, mainly as a result of grime buildup which retains contaminated moisture permitting attack of the surface thereby damaging the finish.
What to use?
The cleaning procedure adopted will depend on the current condition of the surface and the time lapsed since last attended.
If regularly maintained, wash down anodised aluminium with warm water containing a suitable wetting agent, or with a mild soap solution. Hand rubbing is often used for small work, for larger projects utensils such as fibre brushes may be more practical.
More difficult grime deposits may require the use of a mild abrasive such as pumice powder and water. Where greasy deposits are concerned, cleaning may require a soft cloth dipped in white spirits.
It is necessary to thoroughly rinse with water after cleaning especially where crevices are present to ensure removal of all residues.
What NOT to use?
The removal of grime by the use of emery paper, sandpaper, steel wool or other highly abrasive materials.
Acid or alkaline cleaners are not recommended as they can damage the anodised coating.
Emulsion cleaners or proprietary chemical agents may also attack the anodised coating therefore they should never be used except in consultation with companies specialising in the cleaning of anodised aluminium.
The frequency with which cleaning should be carried out will range from monthly to six monthly intervals according to the application and environment that the surface is exposed to. The aim of the cleaning operation should be the removal of grime deposited without damage to the anodised coating.
