Panel edge staining

Panel edge staining is a naturally occurring problem that occurs to anodized aluminium and stainless steel panelling and façades.

It is semi-permanent staining that dulls the panel or façade's surface (in particular the edges of the panelling), reducing the natural lustre and shine produced by the anodizing processes used on the aluminium.

Panel edge staining is the by-product of the build-up of dirt and pollution.

It is especially more noticeable on buildings using metallic façades in Asia, and regions close to the equator (such as Florida or South East Asia), as higher rates of air pollution,[1] high levels of humidity and consistent rainfall encourage panel edge staining to develop.
