Step 1 of 2: Manufacturer Recommendations

Official Care Guidance

Glass

• ✓pH-neutral glass cleaner. Microfibre T-bar and professional squeegee.
• ✓Residential: standard tilt-and-turn or casement cleaning technique.
• ✓Commercial facade: bay-by-bay from top to bottom. Full-height squeegee passes. Control solution run-off to lower bays.
• ✓Check for solar control glass coating type before using abrasive tools on commercial glass.

Frames

• ✓pH-neutral aluminium cleaner on soft cloth. No alkaline products on powder coat or anodised sections.
• ✓Rinse immediately after applying cleaner. Dry with chamois on high-gloss or commercial facade sections.
• ✓Clear drainage weep holes in horizontal transom members on curtain walling and facade systems.
• ✓Check sealant condition on commercial installations at every clean.

Hardware

• ✓Residential window hardware: annual lubrication with light oil or PTFE at all mechanism points.
• ✓Commercial door hardware: bi-annual lubrication due to high daily-cycle use.
• ✓Industrial systems: confirm lubricant operating temperature range before applying.

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 Yawal 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 Yawal 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 Yawal 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 Yawal 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

• ★ Yawal's range from residential to industrial means a contractor working with this brand across multiple clients needs to be fluent in residential, commercial, and industrial window maintenance approaches. Each is a separate skill set.
• ★ Polish commercial construction using Yawal curtain walling is among the most demanding cleaning environment in central European window maintenance. The commercial building manager and the architect who specified Yawal are both visually aware clients.
• ★ Weep hole clearing on Yawal commercial facades is the most consequential single maintenance action. A commercial building manager's call reporting an internal water leak is almost always preceded by a blocked weep hole that a cleaning visit missed.
• ★ pH-neutral aluminium cleaner is the only acceptable product on Yawal powder coat and anodised sections. This is not a conservative recommendation - alkaline attack on powder coat is cumulative and irreversible. The correct product costs the same as the wrong one.
• ★ Industrial Yawal installations in cold-store environments operate at temperatures that thin or solidify standard lubricants. A lubricant that performs at -20 C is not a standard product - confirm the specification with the facility manager before applying anything to industrial Yawal hardware.
• ★ Raking light inspection is the quality assurance step on any Yawal commercial facade clean. A facade that looks clean from the front of the gondola shows streaks and missed sections when viewed in raking light from the side. Build the raking light check into the gondola travel protocol.
• ★ New Yawal commercial facades in Polish construction sometimes have residue from the construction process: silicone sealant smears, cement splatter, and metal swarf from cutting operations. Post-construction cleaning is a specialist task that requires specific products for each deposit type. Standard maintenance cleaning does not address post-construction deposits.

What NOT To Do

Bundle Kits and Tool Recommendations

Cleaning Frequency

Glass - residential: 2 to 3x per year (Polish residential standard.). Glass - commercial facade: 3 to 4x per year (Commercial building schedule. Higher in prestige locations.). Drainage channels - commercial: Twice per year minimum (Autumn and spring weep hole clearing on curtain walling.). Hardware lubrication: Annual residential, bi-annual commercial (Industrial: confirm lubricant specification with facility manager.)

Field Notes

“Yawal is one of Poland's leading aluminium profile manufacturers. Their commercial facade systems appear in premium Polish commercial construction and represent a demanding maintenance context where product quality and client expectation are both elevated. The breadth of Yawal applications - from residential windows to industrial glazing - requires maintenance providers to scale their approach correctly. The same brand does not mean the same protocol. Weep hole maintenance on Yawal commercial curtain walling is the single maintenance action that most directly prevents a serious building management incident. It takes minutes per bay and prevents hours of incident investigation.”
