Why This System
Manufactured and engineered specifically for Russia's extreme continental climate - profiles tested for performance at -50°C. Multiple profile series covering budget residential through to high-performance thermal specifications. Wide distribution network across Russia and CIS ensures spare parts and components are regionally available. GOST-certified production - the mandatory Russian state standard for window profiles.
Proplex uPVC profiles are found across a vast range of Russian housing stock from Soviet-era replacement windows through to new residential developments. The profile quality varies by series. All uPVC frames follow the same cleaning principles: mild detergents, no solvents, always rinse. In Russia's harsh winters, frames often accumulate road salt, ice treatment chemicals, and industrial grime that require appropriate pre-cleaning steps.

The Orloffs Protocol
This is how I clean Proplex windows. The tools and technique below come from 25 years of daily professional work on the glass. Every step has been tested on real installations and adapted specifically for Proplex systems.
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 Proplex 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 Proplex 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 Proplex 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 Proplex 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
- Always rinse uPVC frames with clean water after cleaning - dried detergent residue burns into the surface permanently.
- Road salt and ice treatment chemicals are the most damaging deposits on Russian residential windows - clean promptly after winter.
- Never use solvent-based products on any uPVC component.
- UV yellowing on south-facing frames is a material change, not a cleaning issue - document and report to the client.
What NOT To Do
- Do not use solvent-based cleaners, acetone, or paint thinners on uPVC frames.
- Do not use abrasive pads or steel wool on any surface.
- Do not allow detergent to dry on uPVC frames - rinse immediately.
- Do not ignore blocked weep holes in freeze-thaw climates.

Frequently Asked Questions
Field Notes
“Proplex windows are found in enormous quantities across Russian multi-storey residential buildings. Access to upper floors requires scaffolding, rope access, or a water-fed pole system on most high-rise sites. The post-winter clean is the most critical of the year - road salt and ice-melt chemicals sit on frames through the entire heating season and cause accelerated surface deterioration if not removed promptly.”
