Why This System

LX Hausys FENEST profiles are engineered for Korea's climate duality: deep cold winters requiring strong thermal performance, and humid summers that stress frame seals and glazing unit edges. The combination of multi-chamber uPVC profiles with energy-rated glazing units is standard across the range - cleaning that damages seals or glazing edges directly undermines the reason these windows were installed.

Korea's yellow dust season (March to May) deposits a fine, alkaline-leaning particulate on every external surface. On uPVC profiles, dry yellow dust ground in by rain becomes abrasive. On Low-E glass, if it is scrubbed rather than soaked and squeegeed, surface micro-scratches reduce coating effectiveness. The correct approach is pre-soak, not scrub.

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 LX Hausys windows to a professional standard โ€” guaranteed.

Pro Tools

My daily tool list. This is what I carry to every job.

1Microfiber T-bar applicator, kept clean and rinsed regularly to prevent grit
2Professional squeegee with a fresh rubber blade
3Extension pole for glass above arm height
4Bucket with at least 10 litres of water and enough soap for cleaning power without excess foam
5100% cotton towelling rags for edge detailing
6Vacuum for sill tracks and base profiles

Follow these steps in order. Each one builds on the last. This is the same sequence I use on every LX Hausys installation.

  1. 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. 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.

  3. 3

    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 LX Hausys 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. 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. 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 LX Hausys 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. 6

    Frame wipe and hardware check

    On LX Hausys 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

  • During yellow dust season, double your cleaning frequency and always pre-rinse before any other step - dry-scrubbing yellow dust on glass or uPVC causes surface abrasion.
  • In winter, check for ice at frame bases and weep hole exits before cleaning. Ice in drainage channels means water is trapped inside the frame - do not pressure rinse until it has thawed.
  • Never use alkaline or high-pH cleaners on FENEST uPVC profiles - Korean yellow dust is already slightly alkaline and combined residue accelerates profile yellowing.

What NOT To Do

  • Do not dry-scrub frames or glass during or after yellow dust season - pre-rinse first, always.
  • Do not use abrasive pads or scouring powders on uPVC profiles.
  • Do not pressure wash directly into glazing unit edges or frame joints - Korea's thermal systems rely on intact seals.

Field Notes

โ€œYellow dust settles in every track groove, weep hole, and frame joint. On sliding FENEST windows, clean the interlock channel every visit during spring - packed yellow dust causes seal wear and operational stiffness within one season if left. On high-floor installations, yellow dust soiling on north-facing elevations is lighter; south and west elevations take the heaviest loading.โ€
