Why This System

Solid timber construction — the most environmentally considered choice in Scandinavian building culture. Painted or lacquered finishes — each requires careful moisture management during cleaning. Regional manufacturer: windows appear across Swedish homes in a range of ages and paint conditions.

Timber windows demand a different discipline than uPVC or aluminium. Moisture is the primary risk. The glass gets the full professional treatment; the timber gets the minimum effective moisture exposure.

Step 2 of 2: The Orloffs Protocol

The Orloffs Protocol

This is how I clean Forsbacka Fönster 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 Forsbacka Fönster systems.

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 Forsbacka Fönster 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 timber 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 Forsbacka Fonster timber 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 Forsbacka Fonster 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 Forsbacka Fonster timber frames: use a barely damp cloth and dry immediately. Never allow water to sit on timber joints or frame corners -- moisture causes swelling and paint failure.

    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

  • Moisture is the primary risk on timber windows — keep all surfaces as dry as possible.
  • Never allow soap water to pool in painted timber joints or on sills.
  • Inspect the base of the frame for soft timber at every visit.

What NOT To Do

  • Do not allow water to pool on painted timber sills or reveals.
  • Do not use solvent or alkaline cleaners near timber finishes.
  • Do not ignore soft spots at the base of the frame.
