Why This System
Jangho facades are bespoke engineering projects - each landmark building has a facade system designed specifically for that project's geometry, structural loads, and performance requirements. This means there is no standard Jangho window to clean: there is a specific facade system with specific drainage routes, specific panel joint types, specific structural silicone exposures, and specific access equipment requirements designed and documented for that building. Cleaning a Jangho facade without understanding the system design and approved access methodology is a risk - both to the facade and to the cleaner.
High-performance curtain wall glass in Jangho systems is typically specified to the highest available standards: triple Low-E coatings, solar control glass, high-visible-light-transmission coatings. These coatings are applied to inner surfaces of insulated units and are not accessible for cleaning, but they make correct outer surface cleaning non-negotiable. Any surface scratching on the outer glass face of a triple-coated unit reduces optical clarity and scatters light through the coating stack. Structural silicone joints at panel perimeters must not be cleaned with solvent-based products - silicone solvents cause silicone shrinkage and joint failure.

The Orloffs Protocol
This is how I clean Jangho Facade 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 Jangho Facade 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 Jangho Facade installation.
- 1
1. Review the building facade maintenance manual before starting any cleaning operation. Jangho landmark buildings typically have a building management unit (BMU) system and specific cleaning protocols. Do not deviate from the approved access methodology.

2. Pre-rinse panels with clean water from the BMU or approved access equipment. On large unitised curtain wall panels, rinse in sections.

3. Apply pH-neutral cleaning solution appropriate for the glass specification. Confirm product compatibility with any solar control or specialty coating specified by the project documentation.

4. Squeegee glass panels with fresh, nick-free rubber. On large curtain wall panels (often 1.5m x 3m or larger), work in horizontal sections from the BMU cradle.

5. Wipe aluminium panel frames with a separate microfibre cloth. Do not clean structural silicone joints with solvent-based products under any circumstances.
Pro Tips
- Jangho facade systems on landmark buildings require facade maintenance plans - request this documentation from the building management team before starting a new contract. The plan documents access equipment, approved cleaning products, and no-go zones.
- Structural silicone joints on Jangho unitised systems must be inspected during each cleaning visit - cleaning access presents the best opportunity to identify joint degradation early. Note and photograph any joint cracking or silicone shrinkage.
- On Jangho double-skin facade systems, the inner skin and cavity require separate specialist cleaning protocols - do not apply standard single-skin cleaning approaches to double-skin elevations without understanding the specific drainage and ventilation design.
What NOT To Do
- Do not use solvent-based cleaners on or near structural silicone joints on any Jangho facade panel.
- Do not use abrasive materials on high-performance coated curtain wall glass.
- Do not access Jangho facades via non-approved methods - engineered access systems are specified for structural and safety reasons, not convenience.

Typically quarterly on high-profile landmark facades in line with building maintenance plans. Frequency may increase for facades in high-pollution urban environments (Beijing, Shanghai, Middle East) or coastal salt-air locations. Frequency is specified in the building facade maintenance plan - follow that, not a generic schedule.
Frequently Asked Questions
Field Notes
βJangho facades represent the top tier of complexity in professional facade cleaning. The skills required - rope access, BMU operation, high-performance glass care, structural silicone awareness, and complex drainage system understanding - go well beyond standard window cleaning. If you are being asked to clean a Jangho-designed curtain wall facade without formal rope access qualifications and a reviewed facade maintenance plan, decline the work and refer to a specialist facade contractor.β
