Why This System
Premium Italian aluminium at Piva Group specification typically uses a higher-build powder coat than northern European mid-range products - the surface is more durable but also more sensitive to alkaline attack, which strips the polyester binder from the coat. Slim sightline residential windows have less frame area to clean but more precise contact between frame and glass bead - the junction between glass bead and frame must be kept clean to prevent water ingress through the bead seal. Southern European installation locations mean high UV exposure on outer aluminium faces - UV-stable powder coat formulations are specified but still benefit from regular cleaning to remove atmospheric deposits before they chemically bond to the coat. Italian commercial facades using Piva Group systems often have structural silicone glazing with minimal or invisible frame lines - cleaning technique must control solution run-off precisely as there are no frame beads to catch excess. The architectural project context means Piva Group installations are often in distinctive buildings where cleaning quality is highly visible from public spaces - technique errors show in a way they would not on a standard residential window.
Step 1 of 2: Manufacturer Recommendations
Official Care Guidance
Source: ORLOFFS PROFESSIONAL GUIDANCE - BASED ON PIVA GROUP PUBLISHED INFORMATION AND 25 YEARS FIELD EXPERIENCE
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.
Step 2 of 2: The Orloffs Protocol
The Orloffs Protocol
This is how I clean Piva Group 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 Piva Group systems.
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
Site and finish assessment
Identify finish type: powder coat or anodised. Check for any existing surface damage before cleaning begins.
On commercial facades, plan the cleaning sequence from top to bottom in vertical bands. Solution must not run onto already-cleaned sections.
On structural silicone facades, identify all silicone joint locations and plan squeegee strokes to minimise solution run-off onto joints.
- 2
Glass cleaning - residential
Apply solution with T-bar in overlapping passes. Squeegee from top to bottom.
Control drips at the hinge side and lock side where hardware is exposed.
Edge wipe in rebate before final squeegee pull. Chamois dry the adjacent frame face.
- 3
Glass cleaning - commercial facade
Work bay by bay, top to bottom. Complete each bay before moving to the next.
Use a longer-channel squeegee for efficiency on large panes. Fresh rubber per session.
On structural silicone facades, finish each panel with a dry chamois pass at the glass-to-silicone junction to remove any solution residue from the silicone face.
- 4
Frame cleaning
Apply pH-neutral cleaner to soft cloth. Wipe in straight strokes. Rinse immediately with clean water.
On anodised sections, apply and rinse immediately - do not allow dwell time.
Final chamois pass on all gloss powder-coat frame faces. View in raking light to confirm no watermarks.
- 5
Bead junction and drainage maintenance
Clear slim sightline glass bead junctions with soft brush. Work along the full bead length.
Check drainage weep holes in horizontal frame members. Clear with soft tool.
On curtain walling, check weep hole covers are in place and correctly fitted after clearing.
- 6
Raking light final inspection
Step back from the facade and view the cleaned surface in raking light or at an angle to the main glass plane.
Any remaining streaks, watermarks, or missed sections are visible at this angle.
Touch up with chamois or clean cloth before leaving the site. The final visual standard must match the premium specification of the product.
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
- Do not use alkaline cleaners on Piva Group powder coat or anodised surfaces - damage accumulates over multiple cleans.
- Do not allow glass cleaning solution to dry on silicone joint faces on structural glazing facades.
- Do not use metal tools near slim-sightline glass bead junctions - aluminium beads scratch easily.
- Do not clean in direct strong sun on southern European elevations - the fast evaporation rate prevents proper rinsing.
- Do not skip the raking light inspection on premium architectural aluminium - it is the quality assurance step that prevents revisits.

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.”
