Why This System
Technal systems are premium commercial and high-specification residential products. Their aluminium profiles are engineered to tighter tolerances than mid-market products - this means drainage paths, gasket seating, and frame geometry are more precise, but also more sensitive to debris accumulation. Thermal break profiles are standard on Technal premium systems. The thermal barrier isolator is a structural and performance component - never introduce cleaning products or tools into the thermal break channel. High-rise Technal installations in Sao Paulo and Rio face the most demanding combination of conditions in Brazilian construction - tropical UV, coastal salt air (Rio), urban particulate (Sao Paulo), and extreme height exposure. Cleaning frequency for these installations should be higher than mid-market products in the same environment.

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 Technal Brazil 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 Technal Brazil 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 Technal Brazil 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 Technal Brazil 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 Technal Brazil 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
- Always request the glazing specification in writing from building management on commercial Technal installations before the first clean
- In Sao Paulo, pre-rinse with pure water before applying cleaning solution on commercial facades - urban particulate is abrasive if ground into the glass surface during cleaning
What NOT To Do
- Do not insert tools into thermal break isolator channels
- Do not use alkaline cleaners on anodised aluminium (pH above 8)
- Do not use acid-based glass cleaners on coated glazing
- Do not pressure wash curtain wall sealant joints
- Do not attempt commercial high-rise Technal cleaning without confirmed safe access equipment

Frequently Asked Questions
Field Notes
โRio de Janeiro Technal installations on coastal towers face the highest combined stress in Brazil - tropical UV, ocean salt air, and extreme height. Inspect sealant on south and north-facing elevations at every visit. Sao Paulo urban Technal towers accumulate a particulate load from traffic and industrial pollution that is different from coastal salt deposit. The grime is darker and more chemically complex - pure water pre-rinsing before applying cleaning solution is important on these installations.โ
