Kestrel entrance door systems are built to withstand high-traffic commercial use - the frame profiles are heavier section than residential aluminium and the hardware is heavy-duty. This robustness means the cleaning challenge is grime volume, not frame fragility. Ground-floor commercial glass accumulates a distinct contamination profile from residential windows - vehicle exhaust films, tyre splash, fast food grease, chewing gum adhesive on the door base, and fingerprint smear zones at handle height. UK high street shopfronts face significant grime accumulation between cleans, particularly in wet weather when road spray reaches 2 to 3 metres up the glazing.

This is how I clean Kestrel Aluminium Systems 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 Kestrel Aluminium Systems systems.

• ✕Do not use blades on powder-coated or anodised Kestrel aluminium frames
• ✕Do not use abrasive pads on any Kestrel aluminium surface
• ✕Do not use alkaline degreasers on powder-coated frames - the degreaser is for the glass only
• ✕Do not apply any cleaning product to glass before confirming whether an anti-graffiti coating is present
• ✕Do not skip the door threshold seal check - a failed seal is a water ingress risk and a slipping hazard from the water track inside the entrance
