The Yullard projected window is the product most associated with the Shin Nikkei name. These outward-projecting windows on older Japanese office buildings have a specific cleaning challenge - the outer face of the projected panel is inaccessible from inside and from the standard rope-down or MEWP position when the window is closed. Protocols for access need to account for this. Shin Nikkei's commercial systems frequently used anodised aluminium finishes - the standard for Japanese commercial construction in their era. Anodised aluminium requires pH-neutral products only.

This is how I clean Shin Nikkei 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 Shin Nikkei systems.

• ✕Do not use alkaline or acidic cleaners on anodised Shin Nikkei frames
• ✕Do not use abrasive pads on any surface
• ✕Do not attempt to clean projected window outer faces without a confirmed access protocol
• ✕Do not pressure wash into aged seals on pre-2000 installations
