Official Care Guidance

Glass

• ✓pH-neutral glass cleaner in warm water. Microfibre T-bar and professional squeegee. Fresh rubber blade.
• ✓On structural silicone facades, control solution run-off carefully. Solution on silicone joint faces deposits residue that bonds over time.
• ✓Work in sections on large commercial panels. Do not allow solution to dry on glass in direct southern sun.
• ✓Final edge wipe before squeegee pull. Raking light inspection after each bay.

Frames

• ✓pH-neutral aluminium cleaner only. No alkaline products, no acidic products, no solvents on powder coat.
• ✓Soft cloth, straight strokes, immediate rinse after cleaner application. Dry with chamois.
• ✓On anodised sections, use even more controlled pH - anodising is integral to the aluminium and alkali damage is irreversible.
• ✓Clear slim sightline glass bead junctions with a soft brush. No metal tools near these junctions.

Hardware

• ✓Premium aluminium hardware typically uses concealed mechanisms - lubrication points may require the handle cover plate to be removed for access.
• ✓Apply PTFE lubricant to accessible moving points annually. Light machine oil on exposed hinge points.
• ✓Check structural silicone bead condition on facades annually. Report any cracking or adhesion loss immediately.

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 Piva Group 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 Piva Group 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 Piva Group 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 Piva Group 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

• ★ Never clean Piva Group powder-coat frames in direct strong southern sun - the cleaner evaporates too fast to allow a clean rinse and leaves residue baked into the coat surface.
• ★ Raking light inspection is not optional on premium Italian aluminium - it is the only reliable way to detect watermarks and streaks on high-gloss surfaces before leaving the site.
• ★ Structural silicone on Italian facades is typically a light grey or bronze colour. Solution residue drying on silicone changes the surface to a slightly darker shade. Prevent it by keeping solution off the silicone face, not by cleaning the silicone with solvent.
• ★ Slim-sightline windows have a very narrow frame face visible from outside. Even a single streak on this narrow face is proportionally very visible. Use a chamois for the final frame pass on slim-profile windows.
• ★ Anodised aluminium sections on Piva Group facades are most common in natural silver on residential products and in bronze or champagne on commercial projects. Both respond identically to alkali attack - prevent rather than cure.
• ★ On lift-and-slide doors at this specification level, the concealed running gear is precision engineered. Do not apply heavy grease to the track - PTFE spray on the running surfaces and roller axles is sufficient and will not attract grit.
• ★ High-gloss black powder coat on premium Italian windows is the hardest finish to clean streak-free. Use distilled water for the final squeegee pass if the local mains water is very hard.

What NOT To Do

Bundle Kits and Tool Recommendations

Cleaning Frequency

Glass: 4x per year (Southern European UV locations. Residential 2x minimum, commercial quarterly.). Frames: Same visit as glass (More frequent in coastal or high-pollution locations to prevent deposit bonding.). Structural silicone inspection: Once per year (Annual condition check. Any cracking or adhesion loss needs specialist repair immediately.). Hardware lubrication: Once per year (More frequent on high-use lift-and-slide doors.)

Frequently Asked Questions

Field Notes

“Piva Group installations appear in higher-specification Italian residential and commercial projects. The client profile is design-conscious and the cleaning quality standard needs to match the specification. The most common cleaning error on Italian premium powder coat is alkaline product use. In the Italian market, strong alkaline tile and concrete cleaners are common household products. They are entirely wrong for aluminium window frames. Structural silicone glazing maintenance is underspecified in most cleaning contracts. Add an annual structural sealant condition report as a standard service item on commercial Piva Group installations.”
