Care & Maintenance of Anodised Joinery
A Consumer's Guide

Anodised aluminium joinery is not only attractive, but also offers a durable and tough wearing finish.

Some deterioration of the anodic oxide coating occurs mainly as a result of grime deposition and subsequent attack by moisture, particularly when it is contaminated with sulphur compounds. Regular cleaning is essential if the finish of anodised aluminium is to be preserved over a long period.

Cleaning
The anodised aluminium should be washed down with warm water and a suitable wetting agent or mild soap solution, in a similar manner to washing a car. Fine brushes may be used to loosen attached dirt/grime - the use of anything stiffer or more abrasive may result in damage to the surface. Acid or alkali cleaners should not be used, as these will damage anodic films and may discolour coloured joinery.

Where greasy deposits or hard to remove grime is present, cleaning of the anodising may be by means of a soft cloth dipped in white spirit, turpentine, kerosene, or a mild liquid scourer followed by wiping with a dry rag. Make sure none of these solvents come into contact with other parts of the window.

Note Well: All Solvents must be kept from contact with the vinyl glazing gasket materials, as most solvents damage glazing gaskets (the "rubber" seal around the glass).

It is essential to rinse thoroughly, after cleaning, with copious applications of clean water particularly where crevices are present, and then dry the glass to avoid any marks developing.

Regular washing of your anodised joinery will ensure a long lasting product. In general the following programme is recommended:

Rural: Every six months
Urban: Every three months
Industrial and Marine environments: (within 1 km of the sea): Six monthly warm water detergent wash, as well as monthly cold water washing.

For additional protection, especially in harsh environments, waxing with a good quality car wax after washing will assist in lifting and maintaining the appearance of your anodised joinery.

What to do about paint splashes
Working around your house, painting overhead roof soffits and the like, may cause paint splashes to mar the appearance of your windows. The best thing to do is to act quickly and remove such splashes with a soft cloth moistened with water. Using water-based paints allows you to clean up with water - using solvents may put your joinery at risk.
