Secondary glazing means two glass surfaces with a cavity between them. The outer glass surface faces the weather - it accumulates external grime, UK acid rain deposits, salt air, and biological growth. The inner Selectaglaze panel faces the interior - it accumulates indoor dust, condensation residue, and fingerprint smear from people touching the panel. The cavity between the outer window and the Selectaglaze inner panel is a condensation zone in UK damp conditions. Condensation on the inner face of the outer glass pane - the cavity-facing surface - is the surface that cleaners most commonly miss. It is not accessible without opening or removing the Selectaglaze panel. Selectaglaze aluminium frames are anodised or powder-coated. The cleaning approach for the frame follows aluminium protocol - pH-neutral, soft cloth, no abrasives. Fixed secondary glazing panels cannot be opened - accessing both glass surfaces requires the Selectaglaze panel to be removed from its frame by a competent person. Window cleaners should not remove fixed secondary glazing panels unless they are trained and contracted to do so.

This is how I clean Selectaglaze 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 Selectaglaze systems.

• ✕Do not clean only the outer glass face and leave the cavity-facing surfaces - this is the most common secondary glazing cleaning failure
• ✕Do not attempt to remove fixed Selectaglaze panels unless contracted and trained to do so
• ✕Do not use abrasive pads on Selectaglaze anodised or powder-coated aluminium frames
• ✕Do not use alkaline cleaners on anodised Selectaglaze aluminium frames
• ✕Do not force Selectaglaze sliding panels if they are stiff - check the channel guide condition before applying force
• ✕Do not use acidic cleaners on the outer heritage window frames
