Why This System

Secondary glazing means two glass surfaces with a cavity between them. The outer glass surface faces the weather - it accumulates external grime, UK acid rain deposits, salt air, and biological growth. The inner Selectaglaze panel faces the interior - it accumulates indoor dust, condensation residue, and fingerprint smear from people touching the panel. The cavity between the outer window and the Selectaglaze inner panel is a condensation zone in UK damp conditions. Condensation on the inner face of the outer glass pane - the cavity-facing surface - is the surface that cleaners most commonly miss. It is not accessible without opening or removing the Selectaglaze panel. Selectaglaze aluminium frames are anodised or powder-coated. The cleaning approach for the frame follows aluminium protocol - pH-neutral, soft cloth, no abrasives. Fixed secondary glazing panels cannot be opened - accessing both glass surfaces requires the Selectaglaze panel to be removed from its frame by a competent person. Window cleaners should not remove fixed secondary glazing panels unless they are trained and contracted to do so.

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 Selectaglaze 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 Selectaglaze 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 Selectaglaze 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 Selectaglaze 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 Selectaglaze 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 Selectaglaze 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

  • Create a four-surface checklist for every Selectaglaze property - outer glass outer, outer glass inner, Selectaglaze outer, Selectaglaze inner - and check it off at every visit
  • When quoting a Selectaglaze property for the first time, open a panel to assess the cavity-facing surface condition - heavy condensation residue on first clean requires significantly more time than a maintained cavity
  • If building owners ask why their Selectaglaze windows still look hazy after a standard clean, the answer is almost always the cavity-facing surfaces. Demonstrating the four-surface approach on one window is the most effective way to show the value of a specialist secondary glazing clean

What NOT To Do

  • Do not clean only the outer glass face and leave the cavity-facing surfaces - this is the most common secondary glazing cleaning failure
  • Do not attempt to remove fixed Selectaglaze panels unless contracted and trained to do so
  • Do not use abrasive pads on Selectaglaze anodised or powder-coated aluminium frames
  • Do not use alkaline cleaners on anodised Selectaglaze aluminium frames
  • Do not force Selectaglaze sliding panels if they are stiff - check the channel guide condition before applying force
  • Do not use acidic cleaners on the outer heritage window frames

Field Notes

โ€œSelectaglaze installations on listed buildings in London and other major UK cities are often in properties where the building owner is highly attentive to condition. A thorough four-surface clean that addresses the cavity-facing surfaces is noticeable - and valued. Heritage buildings with original timber outer windows and Selectaglaze secondary glazing are common in UK conservation areas. The outer timber window may be painted, single-glazed, and in varying states of maintenance. Do not attempt to paint or repair the outer timber window - clean only. Condensation on the cavity-facing inner face of the outer glass is a common complaint from Selectaglaze building owners. It is not a cleaning failure - it is a ventilation issue in the cavity. Cleaning the surface removes the visual evidence but does not address the cause.โ€
