Official Care Guidance

Glass

• ✓pH-neutral glass cleaner in warm water. Microfibre T-bar and professional squeegee. Inner face in tilt, outer face in turn position.
• ✓Squeegee top to bottom. Wipe rubber after each pass. Edge wipe in rebate before final pull.
• ✓Check glass unit seal condition at each visit. Note any unit with visible moisture between the panes.
• ✓On entrance door glazed panels, clean the door glass on the same visit as the windows.

Frames

• ✓pH-neutral solvent-free PVC cleaner on damp cloth. Straight strokes top to bottom.
• ✓On colour foil frames, minimal moisture and no pressure near seam edges at corners and cut surfaces.
• ✓Rinse with clean water. Dry with cotton cloth. Do not leave cleaner residue on PVC.
• ✓Clear all sash drainage slots after every frame clean.

Hardware

• ✓Annual lubrication: hinge scissors, corner transfer pieces, espagnolette rod guides.
• ✓Wipe hardware at every clean. Dry immediately to prevent surface rust on steel components.
• ✓Condition rubber seals annually with non-silicone seal conditioner.

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 Plastimet 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 uPVC 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 Plastimet uPVC 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 Plastimet 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 Plastimet uPVC frames: solvent-free pH-neutral cleaner only -- solvents cause permanent surface damage. Avoid abrasive pads on the profile.

   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

• ★ On a building with multiple Plastimet windows, set up one product station and work methodically through each window in sequence. Consistency across the building is more time-efficient than adapting product and technique window by window.
• ★ Plastimet woodgrain foil windows are popular in Polish residential architecture. The oak and mahogany foil options look premium but are maintained the same way as any other foil laminate - solvent-free and gentle.
• ★ Check the inner face of the drainage slots as well as the outer face on tilt-and-turn windows. Debris sometimes blocks from the inner side, particularly in windows adjacent to kitchen or bathroom ventilation.
• ★ Polish PVC frames in high-humidity interior environments - bathroom windows particularly - show faster rubber seal deterioration than windows in drier rooms. Increase seal conditioning frequency on bathroom windows to twice yearly.
• ★ A window that is noticeably colder at the glass edge in winter than at the centre of the glass has a thermal bridge at the glass unit spacer bar. This is a glazing unit issue, not a cleaning issue, but noting it during the clean is a useful service for the property owner.
• ★ Entrance door hinges on Plastimet doors carry significantly more load than window hinges. Include entrance door hinge lubrication in the annual hardware service schedule.
• ★ If a Plastimet tilt-and-turn window will only tilt and not open to the turn position, the handle is in the tilt position and needs to be returned to closed before re-operating. This is a user error rather than a hardware fault but is commonly reported as a fault by property owners.

What NOT To Do

Bundle Kits and Tool Recommendations

Cleaning Frequency

Glass: 2x per year (Residential standard. Urban and roadside locations: quarterly in winter months.). Frames: 2x per year (Same visit as glass.). Drainage slots: Every clean (Non-negotiable on mid-range PVC.). Hardware lubrication and seal conditioning: Once per year (Twice per year on high-cycle terrace and balcony doors.)

Field Notes

“Plastimet windows represent a large proportion of the Polish residential window stock. Correct maintenance protocol is the same for Plastimet as for other mid-range Polish PVC manufacturers - the product follows standard central European construction. The foil laminate issue is the most frequently encountered cleaning damage on Polish mid-range windows. Every operative working on Polish residential windows needs to understand solvent-free protocol before starting. Annual hardware service on a building with 20 Plastimet windows takes approximately 3 hours. Skipping it for 3 years produces a building where half the windows have stiff or incomplete locking - the catch-up work takes significantly longer.”
