Our deionization system filters the water down to zero dissolved minerals — the very things that leave water spots and streaks on San Jose glass.
A soft brush running with that pure water lifts the greasy traffic film, pollen, and grime off each window without abrasive scrubbing.
A final pure-water rinse carries the loosened dirt away and dries clean off the glass, leaving no spots, streaks, or residue behind.
Screens and frames are part of every job at no extra cost, so trapped city dust doesn't rinse straight back onto the fresh glass.
Across San Jose the usual DIY approach backfires. A squeegee leaves a thin soap line that city traffic film and pollen stick to within days, and in the many hard-water pockets, any tap-water drip dries into a cloudy mineral spot that only builds up over time.
Deionized water is the fix because it carries none of that baggage. Every mineral is filtered out before it touches your glass, so when it dries there's no soap and no residue left to haze the view — the windows come genuinely clean and keep their clarity through the next round of city grime.
For the two- and three-storey homes common across San Jose, a water-fed pole sends that purified water up to the top panes from the safety of the ground. No ladders against the house, and the high windows finish just as spot-free as the ones at eye level.
Across San Jose the grime on your glass depends on the neighborhood, but it's usually a combination: urban traffic film and pollution haze citywide, pollen in the tree-lined areas like Willow Glen and the Rose Garden, and hard-water spotting wherever sprinklers or irrigation overspray hit the lower panes and dry.
That mix doesn't wipe clean. The traffic film is greasy and smears, the pollen turns sticky, and the hard-water minerals dry into cloudy spots that ordinary cleaner only redistributes — and leaves its own residue behind as it dries. Within days the windows look hazy again.
We clean with deionized water that cuts the urban film and dissolves the mineral spotting, then dries completely clear because the water is mineral-free — no chemicals, screens included. Whether you're in Almaden, Berryessa, or Cambrian, text your address and we'll count the windows and quote you in 30 minutes.

ORS Clean focuses on exterior window cleaning. Exterior cleaning removes traffic pollution, construction dust, hard water deposits, and grime that account for most of the visible dirt on San Jose home windows. Text (408) 476-3891 to discuss your specific needs.
San Jose's water supply — sourced from Santa Clara Valley groundwater and imported sources — contains dissolved calcium and magnesium. Every time sprinkler overspray dries on glass, it leaves a mineral deposit. Deionized water has zero dissolved minerals so nothing is left behind when it dries.
Most San Jose homeowners benefit from window cleaning 1–2 times per year. Traffic pollution from nearby freeways, construction dust from Silicon Valley development, seasonal pollen, and hard water sprinkler overspray accumulate quickly — especially on south and west-facing windows with direct sun exposure.
Yes — ORS Clean offers multi-service discounts when you combine window cleaning with gutter cleaning, pressure washing, roof cleaning, or solar panel cleaning. Text (408) 476-3891 and Matt will put together a bundled quote for your entire property.
Because rain picks up dust and pollution on the way down and leaves a dirty, spotty film as it dries — and in hard-water neighborhoods, sprinkler overspray does the same with minerals. A deionized-water clean removes the film completely and dries clear, so a rain shower doesn't instantly undo it.
Screens are included on every San Jose job — we clean them so trapped dust doesn't wash back onto the glass — and we wipe the sills and frames. If your tracks are packed with grit we can detail those too; just mention it when you text your address.
