Vitro's coating portfolio spans both hard-coat (pyrolytic) and soft-coat (sputter) coatings. This distinction matters enormously for professional cleaners. Pyrolytic hard coatings are baked into the glass surface and are durable to cleaning. Sputter (soft) coatings are applied as a thin metallic film and are located on an interior surface of the IGU - they are never exposed to cleaning. However, if the IGU is broken or the glass is single-pane, a sputter-coated face must not be cleaned with abrasive pads. Mexico's hard water mineral deposits accumulate on Vitro glass at a higher rate than in European or North American soft-water markets. Calcium and magnesium deposits from irrigation water, construction runoff, and mineral-rich municipal water systems are endemic across Mexico. Acid-based mineral removal is a standard service requirement on Mexican Vitro glass. Vitro's commercial glass - Solarban and Vitro Sky - appears on commercial facades across Mexico. At commercial scale, access equipment, facade specification documentation, and correct coating identification are all professional requirements.

This is how I clean Vitro Glass 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 Vitro Glass systems.

• ✕Do not use abrasive pads on any Vitro glass - coated or uncoated
• ✕Do not allow acid mineral removers to contact frame materials - mask all frames before acid application
• ✕Do not use mineral-rich Mexican tap water as a final rinse
• ✕Do not use scrapers on Vitro coated glass without coating location confirmation
• ✕Do not increase acid concentration beyond 5% on Vitro coated glass
