Official Care Guidance

Glass

• ✓Lukewarm water with a small amount of mild soap or a dedicated glass cleaner. Keep water away from the timber inner frame during the glass wash.
• ✓Microfibre T-bar applicator on the wash, professional squeegee on the pull. Fresh rubber blade - triple-glazed units have a slightly different flex than standard double-glazed and a worn rubber blade leaves marks.
• ✓Check for coatings before using any hard tool on the glass. Triple-glazed premium units commonly carry low-E or solar control coatings on inner faces - no razor blades on coated glass.
• ✓Wipe the rebate edge dry after squeegeeing - solution that sits in the timber rebate groove softens the paint or finish at the glass edge over time.

Frames

• ✓Aluminium outer face: wipe with a damp cloth and pH-neutral cleaner. No abrasive pads. No acid or strong alkali products.
• ✓Timber inner face: wipe with a lightly damp cloth only. Dry immediately and completely. Do not use spray cleaners on bare or painted timber.
• ✓The alu-timber junction at the frame perimeter: wipe dry after every clean. Do not allow water to pool at this joint.
• ✓Inspect painted timber faces for any chips or bare patches at each visit - bare timber exposed to condensation or cleaning water will absorb moisture and raise the grain under the paint edge.

Hardware

• ✓Wipe all visible hardware with a damp cloth and dry immediately. Steel components left wet rust quickly in the gap between the hardware and the frame face.
• ✓Lubricate all moving points - hinges, locking bars, tilt-and-turn mechanisms - with a purpose-made window hardware lubricant or light machine oil once per year.
• ✓Check that all locking points engage cleanly with smooth handle operation. Resistance at the handle is the first sign that lubrication is needed.

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 Bruckner Fenster und Türen 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 Bruckner 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 Bruckner 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 Bruckner 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

• ★ Keep a separate T-bar cover for the glass and never use it on timber frames - fibres picked up from painted timber deposit on the glass on the next application pass.
• ★ On oiled timber inner frames, check that the oil finish is intact at the glass rebate edge - bare timber in the rebate absorbs condensation and cleaning water and raises the grain over time.
• ★ The powder-coat on Bruckner's aluminium outer is high quality but will dull over years without occasional treatment with a dedicated aluminium or powder-coat restorer - flag this to owners at the annual visit.
• ★ Sliding system thresholds accumulate grit and debris that wear the threshold seal - brush the threshold channel clear at every clean, not just when it looks dirty.
• ★ On triple-glazed units, a faint internal reflection is normal on certain glass specifications - do not attempt to clean it off. Confirm with the owner before any remedial action.
• ★ If the outer aluminium cladding has surface oxidation or white powdering, a dedicated aluminium cleaner resolves it - standard glass cleaning products will not.
• ★ Timber inner frames that show raised grain or paint lifting near the bottom rail have absorbed water at some point - flag this as a maintenance issue, as it indicates drainage is not working correctly.

What NOT To Do

Bundle Kits and Tool Recommendations

Cleaning Frequency

Glass: 2x per year minimum (Spring and autumn. South-facing elevations and urban locations benefit from quarterly cleaning.). Aluminium frames: 2x per year (Same visit as glass. Annual treatment with aluminium restorer on exposed elevations.). Timber inner frames: As needed (Light wipe at each glass clean. Full inspection and oiling or repainting by a joinery specialist every 3 to 5 years.). Hardware lubrication: Once per year (All moving points. First visit of the year on the autumn or spring clean.)

Frequently Asked Questions

Field Notes

“On Austrian timber-alu installations, the inside face of the frame is almost always the higher-risk surface - the aluminium outer is robust, the painted or oiled timber inner is not forgiving of wet technique. Lift-and-slide threshold seals on premium Austrian systems are machined to very fine tolerances - grit in the threshold channel damages the seal on the first operation after a dirty clean. The alu-timber junction line is where problems start on neglected windows - a dry wipe at the end of every clean takes 30 seconds and prevents the kind of water damage that costs thousands to repair.”
