Brand at a Glance
- Country: Brazil (Latin America operation of German VEKA Group)
- Parent brand: VEKA Group, Germany
- Role in supply chain: uPVC profile supplier - NOT a finished window manufacturer
- End product: uPVC profiles used by Brazilian window fabricators
- Primary materials: uPVC
- Climate context: Tropical humid (where profiles are installed in Brazil)
- See also: VEKA (parent brand guide)
Product Range
- uPVC window profiles
Why This System
VEKA uPVC profiles include UV stabilisers designed to prevent yellowing and embrittlement - but those stabilisers are calibrated for European UV levels. Brazilian tropical UV is significantly more intense, meaning UV degradation on VEKA profiles in Sao Paulo or Rio will appear earlier than on the same profiles installed in Germany. The finished window quality depends on the Brazilian fabricator, not VEKA. The profile material is consistent. The sealing, hardware, and glazing quality varies across fabricators. Inspect finished window quality independently of the VEKA profile designation. In tropical conditions, the most important surface for uPVC maintenance is the seal arrangement. The profile itself is durable. Seals, gaskets, and glazing tape are the vulnerable components in Brazilian humidity.

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 VEKA Latin America 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 VEKA Latin America 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 uPVC 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.

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 VEKA Latam uPVC 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 VEKA Latam 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 VEKA Latam uPVC frames: solvent-free pH-neutral cleaner only -- solvents cause permanent surface damage. Avoid abrasive pads on the profile.
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
- Ask the property manager or building manager which Brazilian fabricator supplied the windows - the fabricator name tells you more about hardware and seal quality than the VEKA profile designation alone
- In tropical Brazil, check the western and northern elevations of uPVC windows first - these faces receive the most UV and show degradation earliest
What NOT To Do
- Do not use solvent-based cleaners on uPVC profiles - solvents cause surface damage and accelerate UV degradation
- Do not use abrasive pads on uPVC frames
- Do not use citrus oil-based cleaners on uPVC
- Do not attempt to clean yellowed uPVC with bleach
- Do not assume the finished window quality matches VEKA profile quality - inspect the fabricator's work independently

Frequently Asked Questions
Field Notes
โBrazilian tropical UV is 30 to 50 percent more intense annually than German UV levels. uPVC UV stabilisers designed for European conditions will show early signs of degradation in Sao Paulo and Rio facing west or north. The fabricator quality behind a VEKA profile varies significantly in Brazil. Inspect the overall window installation - sealing, hardware, glazing - separately from assessing the profile quality.โ
