Why RO/DI Water Makes All the Difference
Tap water contains dissolved minerals — calcium, magnesium, silica — that leave white spots and streaks as water evaporates. Our RO/DI filtration system removes 99.9% of those dissolved solids, producing pure water with a TDS (Total Dissolved Solids) reading near zero. When pure water dries on glass, it leaves nothing behind. No spots. No streaks. No wiping required.

Our Process
Pure Water Prep
We run tap water through our multi-stage RO/DI filtration system until TDS reads near zero — guaranteeing spot-free results before we touch a single window.
Agitate & Scrub
Brushes on our water-fed poles agitate the glass surface, loosening dirt, grime, pollen, and oxidation while pure water continuously rinses.
Pure Water Rinse
A final flood rinse with pure water carries all contaminants off the glass. As it dries, nothing is left behind — no minerals, no soap, no residue.
Inspect & Confirm
We walk every window before we leave. If it's not perfect, we go back over it — no charge, no argument.
