Maintenance of anodized aluminum
6005-T5 anodized aluminum is largely maintenance free. Only in highly polluted or marine conditions is rinsing with clean water required, during scheduled panel cleaning.
Anodizing is surprisingly durable and resilient to corrosion. However, like its aluminum base, it is susceptible to strong alkalines, such as Lye or Sodium Hydroxide. It also can be damaged by strong acids, such as nitric or sulfuric. Beware of strong alkaline cleaners, which often contain ammonia or lye, as well as masonry or cement cleaners, which can contain strong acids.
Surprisingly, anodizing is quite resistant to organic solvents. While alcohol or acetone will quickly remove ink from a permanent marker, for example, they will not damage or fade colored anodizing, and can be excellent for cleaning purposes.
