High Rise Window Cleaning — Roy Street, Albert Park

Hotel glazing on an exposed waterfront-facing block collects a mix of salt-laden air, road film and airborne dust that rinses down the facade with every shower and dries in streaks. On a high-rise elevation none of this can be reached from the ground, so the build-up is left to harden over months. Once mineral deposits bond to the glass they dull the view from guest rooms and start to etch the surface, which no later clean can reverse.

Access was by rope, working each elevation from the top down so that runoff never crossed glass already finished. Rope access lets the crew stop at every window and work it individually, including reveals and frames where deposits collect, rather than sweeping past on a fixed platform. It also avoids setting up plant at street level around a working hotel entrance. A crew of three ran the descents and ground control over four days.

• Frames, reveals and sills cleaned with the glass
