Care & Maintenance
The life of an anodised finish can be greatly enhanced by the implementation of regular documented maintenance. Chemical attacks on decorative surfaces which aren't regularly cleaned become increasingly severe and eventually, may be impossible to restore.
A regular cleaning and maintenance regime is essential for two very good reasons:
1. To maintain a decorative appearance and to reduce any chemical attack, if applicable.
2. To remove dirt, grime, grit, atmospheric pollutants and iridescence.
The cleaning procedures may be broken down into three distinct categories:
The initial cleaning that should occur after completion, to remove atmospheric dust, deposits of dirt, possible cement deposits, glues, etc.
Normally a heavy duty clean that is carried out on a surface that has been neglected for some time. This should be carried out by companies that specialise in the cleaning of facades, windows, doors, curtain walling etc. The most important criteria of an aluminium cleaning agent Is that it should not be toxic, have a pH within 5 - 8 and be free of fluorides, chlorides, or sulphates.
The cleaning cycle that should be done on a regular basis AFTER the primary and secondary phase. (In the case of a new installation etc. it follows after the Primary). The intervals of each cleaning cycle are dependent on the atmospheric pollutants, area, region, corrosive level, etc. for a particular region.
To clean long neglected areas it is advisable to use proprietary cleaners specifically formulated for aluminium surfaces. These products contain residual waxes etc. and can substantially improve the appearance of worn or weathered surfaces.
To ensure that the anodised coating is not attacked by corrosive chemicals, a temporary protective coating can be applied in the form of a suitable non-yellowing lacquer, e.g. methyl methacrylate or cellulose acetate butyrate, or a removable coating or tape is recommended. Tape and stripable coatings should be easily removable and should not leave residues.
