Why This System

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.

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 Vitro Glass windows to a professional standard — guaranteed.

Pro Tools

My daily tool list. This is what I carry to every job.

1Microfiber T-bar applicator, kept clean and rinsed regularly to prevent grit
2Professional squeegee with a fresh rubber blade
3Extension pole for glass above arm height
4Bucket with at least 10 litres of water and enough soap for cleaning power without excess foam
5100% cotton towelling rags for edge detailing
6Vacuum for sill tracks and base profiles

Follow these steps in order. Each one builds on the last. This is the same sequence I use on every Vitro Glass 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 glass 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 Vitro Glass glass 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 Vitro Glass 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 glass from Vitro Glass: use pH-neutral solution only on all coated surfaces. Any coating damage -- Low-E, self-cleaning, solar control -- is permanent and the unit must be replaced.

    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 a small LED torch on Mexico jobs - hold it at a raking angle to the glass surface to reveal mineral deposits before they are visible in normal light. This allows you to identify deposits before cleaning and demonstrate the result to clients
  • On Vitro coated commercial glass, keep a written note on your job card of the coating type and location for each building - this prevents the coating identification step from needing to be repeated on every visit
  • Offering a hydrophobic sealant application as a service add-on on Vitro glass in hard-water Mexico locations is a legitimate upsell - the client benefit is real and the application is straightforward

What NOT To Do

  • 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

Field Notes

Vitro glass is in virtually every Mexican window regardless of the frame brand - cleaning professionals in Mexico are always cleaning Vitro glass whether they know it or not. Vitro's Solarban series coatings are widely used in Mexican commercial facades. On commercial accounts, the coating type and location should be in the building specification. Request it - it is the single most important piece of information for correct cleaning of coated commercial glass. In Mexico's agricultural regions (Sonora, Sinaloa, Guanajuato), irrigation spray from nearby fields deposits mineral-rich water on glass at rates higher than urban areas. Properties near agricultural activity need more frequent mineral deposit removal service.
