Why This System
Epwin's multi-brand operation means their uPVC profile technology underlies a significant proportion of UK trade window installations. The surface cleaning approach is consistent across Profile 22, Spectus, and Swish branded products. PatioMaster sliding door systems are built to a heavier specification than standard sliding windows - the track and roller system is more robust but also accumulates more debris due to the wider track channel. Swish roofline products on the same property as Epwin windows mean the cleaner may be dealing with algae and debris from fascia and soffit that contaminates windows below - particularly on north-facing elevations.

The Orloffs Protocol
This is how I clean Epwin Window Systems 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 Epwin Window Systems 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 Epwin Window Systems 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.
- 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 Epwin Window Systems 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 Epwin Window Systems 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 Epwin Window Systems 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
- When quoting a property with Epwin systems, check whether Swish roofline products are present - they extend the cleaning scope and the time required
- On PatioMaster doors, always clean the inside track face as well as the outer - the inner track accumulates indoor dust and hair that combines with outdoor grime at the bottom rollers
- UK winter grime on Profile 22 white frames is particularly visible - pre-rinsing is more important in winter months than summer because the grime layer is thicker and more adhesive in cold damp conditions
What NOT To Do
- Do not use bleach or chlorine products on any Epwin uPVC surface
- Do not pressure wash soffit or fascia clips on Swish roofline systems
- Do not use abrasive pads on any profile surface across the Epwin brand family
- Do not use solvent-based cleaners near rubber seals or glazing unit edges
- Do not skip trickle ventilator cleaning on Profile 22 casements - blocked vents cause condensation complaints

Frequently Asked Questions
Field Notes
โEpwin systems appear under multiple brand names at the same property - the windows may be Profile 22, the patio door PatioMaster, and the roofline Swish. Clean all surfaces with the same pH-neutral approach. Profile 22 trickle ventilators at the head of casement frames are a consistent blockage point in UK dusty and pollen-heavy spring and autumn seasons. Flag blocked vents to the customer - blocked vents are a building regulation compliance issue in post-2022 UK new-build. PatioMaster patio doors on ground floor rear elevations often have significantly more grime accumulation than upper floor windows due to garden soil splash and pet contact at the base.โ
