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.

This is how I clean Cuprum 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 Cuprum systems.

• ✕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
