“Best window cleaning we've ever had. Schaef and Everett were on time, professional, and the glass looks unreal. Already booked the quarterly plan.”

The Science Behind The Shine
Why Pure Water
Cleaning Works.
Ordinary tap water is loaded with dissolved minerals — calcium, magnesium, silica — that cling to glass as it dries. Our commercial-grade purification system strips them all out, so the only thing left on your windows is a flawless finish.
Removes minerals & impurities
RO + DI filtration strips calcium, magnesium, chlorine, and dissolved solids down to 0 TDS.
Windows dry spot-free
With nothing left in the water, glass air-dries to a perfect, mirror-clear finish — no squeegee streaks.
No soap residue left behind
No detergents, no surfactants, no slick film attracting dust the second the sun hits.
Glass stays cleaner longer
Soap residue draws dirt back fast. Pure water keeps windows looking just-cleaned for weeks longer.
Frames & surrounds cleaned too
Pure water scrubs and rinses screens, frames, tracks, and sills in the same pass — not just the glass.
Commercial-grade purification
Multi-stage RO/DI system mounted in our rig delivers a constant, on-site supply of ultra-pure water.
Inside Our RigProfessional
Professional
Equipment Matters.
We're not a bucket-and-squeegee operation. First Class Wash is a professional exterior cleaning company — and the gear we run is the reason results look the way they do.
RO / DI Filtration System
Reverse osmosis paired with deionization — the same purification used in laboratories.
Deionized Water Technology
Ion-exchange resin pulls out the last traces of dissolved solids for true 0 TDS rinse.
Water-Fed Carbon Poles
Lightweight carbon-fiber poles reach 3+ stories safely from the ground — no ladders on your siding.
Soft Nylon Brush Systems
Dense, non-scratch brushes agitate grime without harming glass, screens, or seals.
Spot-Free Rinse Process
Final pure-water rinse means windows air-dry to a streak-free, crystal-clear finish.
0 TDS
Total Dissolved Solids · The professional standard
Every job ends with a final rinse from our on-board RO/DI system. We measure it. We verify it. That's the difference between "clean" and first-class.
