Aluminium poles, especially if anodised, have minimal maintenance requirements. As the anodised finish is extremely smooth and slippery the poles will essentially self-clean in rain. Poles in a more hostile environment may require cleaning from time to time by hosing or steam cleaning.
Graffiti or stubborn marks can generally be removed with the use of solvents. Most hydrocarbon solvents such as methylated spirits or acetone can be used. Poles can also be blasted with high-pressure water or steam cleaned.
No form of alkaline cleaner should be used, as aluminium is dissolved by alkalis.
Abrasive cleaners are not recommended as they may scratch the anodising.
Powder coat paint finished poles should be cleaned with soap and water only.
