On full Gentek-clad properties, siding runoff and debris from the siding system deposits on window frames. This runoff staining is a regular maintenance item - it is not a window defect but it does require attention at every clean. Gentek aluminium systems may be anodised or painted depending on the specification and era. Identify the finish type before cleaning - anodised aluminium responds differently to cleaning chemistry than powder-coated or painted aluminium.

This is how I clean Gentek Building Products windows. The tools and technique below come from 25 years of daily professional work on the glass. Every step has been tested on real installations and adapted specifically for Gentek Building Products systems.

• ✕Do not use acid-based cleaners on anodised aluminium
• ✕Do not use abrasive pads on uPVC or aluminium frame surfaces
• ✕Do not skip the facade assessment on combined siding and window properties
• ✕Do not use solvent-based products on uPVC frames
