Why This System
CSG glass is distributed into markets where professional window cleaning infrastructure is less developed - Southeast Asia, the Middle East, and Africa. This matters for building owners and managers: glass installed in these environments is often cleaned with whatever is available rather than appropriate professional products. CSG Low-E glass in these markets is exposed to exactly the kind of wrong cleaning approaches that degrade coating performance: abrasive cloths, alkaline household cleaners, and dry scrubbing.
Southeast Asian humidity and UV loading stress glazing unit seals faster than temperate climates. Middle Eastern sand and dust events (haboob season) deposit fine abrasive particles that must be flushed before any mechanical cleaning action. African coastal sites accumulate salt air loading that attacks spacer bar coatings at unit edges. In all three export markets, pre-rinsing is the non-negotiable first step.

The Orloffs Protocol
Since 1999 I've cleaned hundreds, if not thousands, of different window brands and systems. The physics of clean glass don't change from one brand to the next. Follow the steps below and you'll clean your CSG Holding windows to a professional standard β guaranteed.
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 CSG Holding installation.
- 1
Preparation -- before any water touches the glass
Fill the bucket with at least 10 litres of water. Add soap for cleaning power -- enough to cut through environmental deposits, not so much you are fighting foam.
Before touching the glass, brush down the surface to remove loose dust, spiderwebs, and debris. Any grit left on the glass during the wash phase risks scratching during agitation.
Check the glass frame condition before you start. Confirm which cleaning product is safe for that surface before opening any bottle.
Cover anything below the windows that cannot be moved.
- 2
Agitation -- apply and work the solution
Dip the microfiber T-bar completely into the soap water, both sides. Remove excess water with your hand so it does not drip. Apply the solution across the entire glass surface with overlapping passes.
The goal is to fully dissolve and release every deposit from the glass surface. Anything not released during agitation gets transported across the glass by the squeegee as a smear.
For stubborn spots -- insect marks, salt residue, environmental deposits -- re-apply soap water and allow it to soak for a full minute before agitating again. Use more soap water, not more pressure.
For panels above arm reach: attach the T-bar to an extension pole. Work in sections -- top first, then middle, then bottom -- keeping each section wet until you squeegee it.
Rinse the T-bar cover regularly during the job. A dirty applicator causes microscopic scratches that accumulate over time.

Detail the frame edge before squeegeeing
Use your 100% cotton towelling rag, finger pressed into the fabric, to work into every junction and remove pooled soap water before the squeegee pass.
This prevents drips running down onto already-cleaned areas during squeegeeing and keeps soap water out of drainage channels.
On CSG Holding glass frames, pay particular attention to the bottom edge where glass meets the frame sill -- water pooled here runs into drainage openings and leaves residue over time.
- 4
The squeegee
Tilt the squeegee at a slight angle so soap water spills from one side of the channel only -- not both. If the rubber is jumping or squeaking, either the rubber is not lubricated enough or the glass surface has warmed.
Cutting in: start with the rubber blade making first contact on a dry edge of the glass.
Side to side: horizontal passes across the panel. Works well on wide sections. Top to bottom: vertical passes down the panel. Works well on tall narrow sections.
The J tune: one smooth unbroken motion top to bottom, wrist rotating at each end to reverse without lifting the rubber. The most efficient method on larger panels -- but it requires training before applying it to premium glass.
Wipe the rubber dry after every pass. Overlap each stroke by 2-3 cm.
- 5
Final edge detailing
After squeegeeing, there is always a residual line of water along the bottom edge and at the panel sides. Take a dry cotton rag, fold to a clean corner, and detail these edges in one smooth pass.
On CSG Holding frames, the bottom edge where glass meets the sill requires the most careful attention. Water left here runs into drainage and leaves residue that affects the next clean.
Rotate the rag to a clean section after every pass. If the rag picks up grit at any point, replace it immediately.
- 6
Frame wipe and hardware check
On glass from CSG Holding: use pH-neutral solution only on all coated surfaces. Any coating damage -- Low-E, self-cleaning, solar control -- is permanent and the unit must be replaced.
Check that all drainage openings are clear and unobstructed. Water must be able to flow freely -- a blocked channel leads to accumulation that affects seal performance over time.
Operate every opening window through its full range. Stiff handles or resistance at locking points indicate hardware that needs lubrication. Flag it to the owner rather than forcing it.
Pro Tips
- In Middle Eastern markets after a haboob dust event, never start cleaning without a full pre-rinse - the fine silica in haboob dust is highly abrasive on glass surfaces.
- In Southeast Asian markets, mould growth on EPDM seals and frame gaskets appears faster than in temperate climates - check and note seal condition every visit.
- CSG photovoltaic glass on solar installations requires specialist cleaning protocols separate from architectural glass - do not apply standard architectural glass cleaning products to solar panel glass without confirming compatibility.
What NOT To Do
- Do not use abrasive cleaning materials on CSG Low-E glass.
- Do not skip the pre-rinse step in dusty or sand-exposed environments.
- Do not use alkaline or acid-based cleaners on CSG coated glass units.

Cleaning Frequency
Monthly in tropical Southeast Asian environments. Every 6-8 weeks in Middle Eastern urban environments; after every significant dust event. Every 6-8 weeks on African coastal installations; increase frequency in winter storm seasons.
Frequently Asked Questions
Field Notes
βOn Southeast Asian high-rise projects where CSG glass has been specified, the most common post-construction soiling type is silicone sealant smearing across glass panels from facade joint sealing works. Silicone smear on Low-E glass requires a dedicated silicone remover product - not standard detergent and not mechanical scraping. Confirm product compatibility before treating large elevations.β
