Why This System
Windsor Legend fibreglass frames respond the same as other fibreglass windows - harder than vinyl, non-abrasive tools required. Windsor Pinnacle wood-clad windows require the same aluminium-to-wood junction inspection and interior water isolation as Marvin, Kolbe, and Weather Shield.

The Orloffs Protocol
This is how I clean Windsor Windows & Doors 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 Windsor Windows & Doors systems.
Pro Tools
My daily tool list. This is what I carry to every job.
Follow these steps in order. Each one builds on the last. This is the same sequence I use on every Windsor Windows & Doors installation.

Identify frame material
Vinyl, fibreglass, or wood-clad determines the cleaning approach.

Non-abrasive microfibre with pH-neutral solution on all frame types.

Protect wood interiors on Pinnacle
Position cloth at sill before glass cleaning.
- 4
Squeegee glass and detail
Controlled strokes and lint-free edge finish.
Pro Tips
- Windsor covers three frame types on the same property in some builds. Walk the property first.
