Commercial Window Cleaning — Shearson Crescent

External glass on a three-storey office building collects road film, dust and rain spotting that builds up evenly across every elevation, so the change is gradual and rarely noticed until the glass looks permanently grey. Melbourne's mix of summer dust and wind-driven rain leaves mineral deposits that bond to the surface, and once they dry in place repeated rainfall only adds to them. Upper floors suffer most, since they are the hardest to reach and get cleaned least often.

A water-fed pole system was used so all three storeys could be reached from ground level, with no ladders or access equipment set up around the building. Purified water lifts the film and then dries without leaving mineral spotting, so the glass does not need squeegee contact or detergent residue rinsed off afterwards. Working from the ground also keeps the footpath and entrances clear, which matters on an occupied commercial site during business hours.

• Assessed all external elevations of the three-storey building
• Cleaned approximately 150 external windows using a water-fed pole system
• Worked all three levels from ground level, no access equipment required
• Checked frames and sills for remaining debris as each elevation was completed

• All external glass across three storeys cleaned in a single eight-hour visit
• No spotting or residue left on the glass after drying
• No disruption to building access or occupants during the work
