Recently, KlinClean carried out the exterior glass cleaning project at Dwight School Hanoi – one of Hanoi’s leading modern international schools, featuring an extensive glass façade system that requires high standards of workmanship, occupational safety, and risk management throughout the operation process.
For educational facilities that remain fully operational, exterior glass cleaning involves far more than simply removing dirt from glass surfaces. It requires a professional execution process to ensure absolute safety for students, teachers, staff, and the school’s facilities.
With many years of experience in industrial cleaning and high-rise glass cleaning services, KlinClean developed a dedicated execution plan for this project, fully meeting all technical requirements and safety standards prior to implementation.

The unique characteristics of Dwight School Hanoi
Dwight School Hanoi features a modern architectural design with extensive exterior glazing systems, aluminum frames, and canopy structures located at various elevations. This requires the cleaning contractor to possess the capability to deploy multiple specialized access methods, including Boom Lifts, Gondolas, and Rope Access systems.
In addition, the school continues its daily educational and operational activities during the project period. Therefore, all cleaning activities must be carefully managed to minimize disruption to the learning environment while ensuring maximum safety for everyone on site.
Site assessment and work method planning
Before commencing the project, KlinClean’s technical team conducted a comprehensive site survey to assess access conditions, equipment movement routes, anchor point locations, and areas with high pedestrian traffic.
The entire work plan was developed based on a detailed analysis of each section of the facility. Access equipment such as Boom Lifts, Rope Access systems, and supporting tools were fully inspected and certified before deployment.
This thorough assessment enabled KlinClean to select the most effective cleaning method for each location while minimizing potential risks associated with working at height.

KlinClean’s professional glass cleaning process
Following the preparation phase, the project team established safe working zones using warning signs, safety barriers, and dedicated ground personnel.
Areas beneath the work zones were carefully protected to safeguard property and control risks associated with tools or equipment used during high-level operations.
The glass cleaning process followed a professional technical procedure, including the removal of dust and contaminants, application of specialized cleaning solutions, washing with professional cleaning sleeves, squeegee cleaning using high-quality rubber blades, and detailed finishing of glass edges and corners.
In addition to exterior glass surfaces, KlinClean also cleaned aluminum frames, canopies, and related structural components to ensure a consistent appearance across the building facade.
By applying the correct technical procedures, the entire glass system was restored to a high level of transparency, free from water stains, fingerprints, dust, cobwebs, and chemical residues.
Safety comes first
For all high-rise glass cleaning projects, KlinClean considers occupational safety to be the fundamental priority throughout every stage of the operation.
One hundred percent of personnel involved in the project received occupational safety training, working-at-height certification, and a complete briefing on the school’s regulations before commencing work.
All technicians were equipped with appropriate personal protective equipment (PPE), including full-body safety harnesses, independent lifelines, safety helmets, anti-slip footwear, protective gloves, and high-visibility vests.

Every elevated work position was secured using independent anchoring systems in accordance with safety regulations. All tools and equipment used during operations were fitted with anti-drop lanyards to eliminate the risk of falling objects.
KlinClean also maintained a daily inspection procedure for Boom Lifts, Gondolas, Rope Access systems, ropes, and personal protective equipment before the start of each work shift. Only equipment that fully complied with safety requirements was approved for use.
In addition, emergency response and high-angle rescue procedures were prepared in advance to ensure rapid and effective action in any unforeseen situation.
