Why This System

No other window environment combines geothermal mineral deposits, volcanic ash, Atlantic salt and subarctic UV in the same building. GK Gluggar frames are built to survive this - but cleaning them requires understanding each of these deposit types and treating them correctly. Standard Scandinavian cleaning protocols are not enough for Icelandic conditions.

Iceland is a specialist environment. Geothermal water leaves silica and mineral scale on glass that standard glass cleaner cannot remove. Volcanic ash is abrasive - wiping dry ash scratches glass instantly. Atlantic salt crystallises in rebates and around fixings. At Orloffs we treat Icelandic windows as a distinct cleaning challenge with dedicated pre-rinse steps and appropriate scale removal products.

Step 1 of 2: Manufacturer Recommendations

Official Care Guidance

No official guide published. The steps below are based on Justin Orloff's 25 years hands-on experience with this system.

Step 2 of 2: The Orloffs Protocol

The Orloffs Protocol

This is how I clean GK Gluggar 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 GK Gluggar 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 GK Gluggar 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 GK Gluggar 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 GK Gluggar 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 GK Gluggar 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

  • Volcanic ash is silica-based - one dry wipe scratches glass permanently. Always flood first
  • Geothermal scale builds fastest on south and west faces where hot spring humidity is highest - plan extra time
  • After Atlantic storms, check drainage channels and sill weep holes - salt blockages cause water ingress

What NOT To Do

  • Do not wipe volcanic ash from glass before flooding with water
  • Do not use standard glass cleaner on geothermal mineral scale - it will not remove it
  • Do not ignore salt crystallisation around fixings - report it as a maintenance issue

Cleaning Frequency

Quarterly recommended for coastal Reykjavik. Post-volcanic-event cleaning should be treated as an emergency call-out - do not leave ash on glass.

Frequently Asked Questions

How often should I clean GK Gluggar windows?
For GK Gluggar windows, Quarterly recommended for coastal Reykjavik. Post-volcanic-event cleaning should be treated as an emergency call-out - do not leave ash on glass.. Coastal or urban locations may need more frequent cleaning.
What tools do I need for GK Gluggar windows?
Professional cleaning of GK Gluggar windows requires my daily tool list of: Microfiber T-bar applicator, kept clean and rinsed regularly to prevent grit, Professional squeegee with a fresh rubber blade, Extension pole for glass above arm height, Bucket with at least 10 litres of water and enough soap for cleaning power without excess foam, 100% cotton towelling rags for edge detailing, Vacuum for sill tracks and base profiles.
What should I avoid on GK Gluggar windows?
Do not wipe volcanic ash from glass before flooding with water
Does GK Gluggar publish an official cleaning guide?
GK Gluggar has not published an official cleaning guide. The protocol on this page is based on Justin Orloff's 25 years hands-on experience.
Can I use a water-fed pole on GK Gluggar windows?
Yes, purified water via a water-fed pole is one of the safest methods for GK Gluggar glass. Ensure TDS is at or near zero before use and avoid directing high-pressure water at seals or gaskets.

Field Notes

โ€œGK Gluggar aluminium windows are designed for high wind loads - the frames are robust, but the seals and fixings are under constant stress in exposed Icelandic locations. A cleaning visit is a good opportunity to check seal condition and report any concerns. Some Icelandic commercial buildings near geothermal activity may need monthly glass maintenance.โ€
