Why This System
Cuprum's dominance of the Mexican aluminium window market means that cleaning professionals working in Mexico will encounter Cuprum systems across virtually every type of property and climate zone. From Mexico City's 2,200-metre altitude and temperate climate to Cancún's sea-level tropical humidity - Cuprum systems span them all. Mexico's hard water is a universal cleaning challenge on Cuprum glass. The calcium and magnesium mineral content of Mexican municipal and well water leaves deposits on glass that are significantly harder than in European or North American markets. These deposits require acid-based removal products - but acid must never contact Cuprum aluminium frames, particularly anodised finishes. Cuprum's coastal hurricane systems (Serie Huracán) use laminated glass with a PVB interlayer - the same technology as Florida impact windows. The same protocol applies: never use abrasive pads near chips in the outer pane, inspect edge seals at every clean.

Step 2 of 2: The Orloffs Protocol
The Orloffs Protocol
Since 1999 I've cleaned hundreds, if not thousands, of different window brands and systems. The physics of clean glass don't change from one brand to the next. Follow the steps below and you'll clean your Cuprum windows to a professional standard — guaranteed.
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 Cuprum installation.
- 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
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.

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 Cuprum 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
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
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 Cuprum 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
Frame wipe and hardware check
On Cuprum 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
- Carry purified water in a spray bottle on every Mexico Cuprum job - use it as the final rinse on glass after squeegeeing to prevent mineral spotting from tap water
- When removing hard water deposits from Cuprum glass, work panel by panel and mask the frame on each panel before applying acid - removing the mask and moving it is slower but protects the aluminium completely
- In Mexico's coastal locations, advise Cuprum homeowners to rinse frames with purified or filtered water after any sea breeze day - this is the lowest-cost maintenance action available to them
What NOT To Do
- Do not allow acid-based mineral removers to contact Cuprum aluminium frames - mask frames before applying acid to glass
- Do not use alkaline cleaners on anodised Cuprum aluminium
- Do not use abrasive pads on anodised aluminium, powder-coated frames, or laminated glass
- Do not use mineral-rich Mexican tap water as a final rinse - use purified or demineralised water
- Do not use scrapers near chips in Serie Huracán laminated glass outer panes

Frequently Asked Questions
Field Notes
“Mexico's hard water mineral deposits are the most frequent cleaning complaint on Cuprum glass. Carrying a purified water supply for the final rinse, and advising clients to rinse glass with purified water between professional cleans, significantly reduces re-deposition. In Mexico's Pacific coastal markets (Los Cabos, Puerto Vallarta, Manzanillo), Cuprum frames in direct ocean-facing positions need the same weekly rinse protocol as South Florida impact windows. Mexico City and Central Plateau Cuprum installations: UV is intense even at altitude. IGU seal degradation is faster than in equivalent northern latitude climates - annual seal inspection is warranted.”
