Why This System
Saint-Gobain India is the market reference for architectural glass quality. COOL-LITE and PLANISTAR coatings are widely specified on commercial buildings across India. For cleaners, this means encountering soft coatings that require coating-safe cleaning protocols on a large proportion of commercial glass surfaces.
Saint-Gobain solar control glass often carries soft coatings (applied via magnetron sputtering) on the inner surface of the outer pane in a double-glazed unit. These coatings are invisible, extremely effective, and permanently damaged by abrasives, acid-based products, or blades. India's climate adds dust, monsoon grime, and UV to the cleaning challenge.

Step 2 of 2: The Orloffs Protocol
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 Saint-Gobain Glass India windows to a professional standard โ 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 Saint-Gobain Glass India 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 Saint-Gobain Glass India 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 Saint-Gobain Glass India 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 Saint-Gobain Glass India: 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
- COOL-LITE and PLANISTAR coatings are on the room-facing surface of the outer pane in an IGU - this surface is protected inside the unit and you will not touch it. The exterior surface is uncoated float glass and safe to clean normally. But if single glazed COOL-LITE is used (uncommon in newer builds), the coating is on the exterior and needs coating-safe products.
- Chennai's high humidity and salt air (coastal proximity) means even uncoated glass carries salt deposits - dwell time with pH-neutral detergent before squeegeeing.
- On commercial facades with Saint-Gobain glass, check silicone glazing tape condition and report any delamination.
What NOT To Do
- Do not use razor blades on any Saint-Gobain coated glass.
- Do not use acidic descalers on solar control glass.
- Do not use abrasive pads on any Saint-Gobain product.

Field Notes
โSaint-Gobain glass is on the majority of commercial buildings across Indian cities. If you are cleaning commercial glass in India, you are almost certainly cleaning Saint-Gobain product. Always assume coating-safe protocols on commercial facades until you have confirmed the glass specification.โ
