Why This System
G.James's Queensland base means their products are engineered with high UV intensity as a baseline - both the glass coatings and the aluminium finishes are specified for tropical and subtropical conditions. As a glass processor, G.James supplies high-performance glass units including low-e coatings and reflective glass. These glass types have specific cleaning requirements - particularly reflective glass, which shows cleaning marks at certain angles. Commercial G.James installations often use anodised aluminium profiles rather than powder coat. Alkaline cleaners on anodised aluminium dissolve the oxide layer - this is a critical distinction on commercial G.James properties.

Official Care Guidance
Source: ORLOFFS PROFESSIONAL GUIDANCE - BASED ON 25 YEARS FIELD EXPERIENCE ON AUSTRALIAN COMMERCIAL AND RESIDENTIAL GLAZING SYSTEMS
Glass
- Pre-rinse all glass with clean water before applying cleaning solution. Essential on Queensland coastal properties.
- Use pH-neutral glass cleaning solution. On reflective glass, use minimal solution and squeegee with clean rubber - wipe after every pull.
- Do not use abrasive pads or scratch pads on any G.James glass - particularly processed and coated glass units.
- Inspect glazing seals at every service. G.James commercial IGUs are high-value units - a failed seal is expensive to replace.
Aluminium Frames
- Identify finish - powder coat or anodised - before selecting cleaning product.
- Powder coat: pH-neutral dampened soft cloth, rinse thoroughly.
- Anodised: pH-neutral only. No alkaline cleaners. Rinse thoroughly after cleaning.
- Do not use abrasive pads on either finish.
Commercial Curtain Wall
- Curtain wall cleaning requires rope access or elevated work platform qualifications. Do not attempt curtain wall work without appropriate height safety certification.
- Use only pH-neutral products on curtain wall aluminium mullions and transoms - commercial anodised and powder coat both require pH-neutral chemistry.
- Pre-rinse curtain wall panels from the top down before applying solution.
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 G.James Glass & Aluminium 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 G.James Glass & Aluminium 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 aluminium 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 GJames aluminium 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 GJames 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 GJames powder-coated aluminium frames: use pH-neutral cleaner only, never abrasive pads or steel wool. Dry immediately after wiping.
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
- On G.James reflective glass, view the cleaned panel at a 45-degree angle under raking light before packing up - this reveals any streaks or missed sections that are invisible when looking at the glass straight on
What NOT To Do
- Do not use alkaline cleaners on anodised G.James aluminium - the oxide layer damage is irreversible
- Do not use abrasive pads on reflective, low-e, or processed glass surfaces
- Do not skip pre-rinsing on Queensland coastal properties
- Do not attempt curtain wall work without height safety certification

Frequently Asked Questions
Field Notes
โG.James commercial properties in Brisbane's CBD show significant salt and pollution accumulation - the river proximity and sea breeze combine to deposit a mixed film that requires thorough pre-rinsing before cleaning. First visits to older G.James commercial properties often reveal mineral staining on the glass from years of inadequate cleaning - allow additional time and consider a mineral deposit treatment as a separate service item.โ
