The water runs through our deionizer until it holds no minerals — the source of the spots and streaks seen on Cupertino glass.
A soft, pure-water-fed brush loosens sap, pollen, or urban film from each pane, depending on your side of town, with no scratching.
A deionized rinse carries the loosened grime off and dries clear on the glass, with no spots or streaks remaining.
Screens and frames are cleaned every visit at no extra charge, so trapped pollen and dust can't wash back onto the windows.
A squeegee struggles on both sides of Cupertino. On the tree-lined west side its soap film catches pollen and sap; on the busier east side it grabs urban dust — and city-wide, hard-water overspray dries into spots the cloth only smears around.
Deionized water handles every version of it. Mineral-free, it lifts sap, pollen, or traffic film and then dries off the glass leaving nothing behind — no soap, no residue — so whichever part of Cupertino you're in, the windows come fully clear and stay that way.
Your upper windows are reached from the ground with a water-fed pole, not a ladder on the siding. The purified water finishes the high panes every bit as spot-free as the ones within arm's reach.
Cupertino windows dirty differently depending on where you are. On the wooded west side toward Monta Vista, tree pollen and sticky sap coat the glass and birds leave droppings; across the flatter east side it's more everyday urban dust and pollution film. Both sides share Cupertino's hard water, which spots the lower panes wherever sprinklers reach.
Sap and pollen smear into a film, urban haze is greasy, and the hard-water minerals dry into cloudy spots that ordinary cleaner only redistributes while leaving fresh residue of its own. The glass looks filmed again within days of a rag-and-bottle wipe.
We clean with deionized water that lifts the sap, pollen, and urban film and dissolves the mineral spotting, drying perfectly clear because it's mineral-free — no chemicals, screens included. Text your address and we'll count the windows and quote you in 30 minutes.

"Matt responded right away and we had a quote within a half an hour. He had availability within 48 hours. He came out on time, was very communicative via texts, and did a fabulous job. They finished in an hour! I would highly recommend Matt!"
"This was an unplanned, but needed job. I noticed my neighbor being serviced by Alex, so I took his business card and called the owner Matt. I received a formal quote/estimate within minutes and Alex had bandwidth to service our home immediately after. ORS is very professional and thorough — we recommend!"
“Had our windows done professionally for the first time and now I understand why people use a service. Every window perfectly clear — no streaks, no residue, screens cleaned. Matt was quick to quote and the crew was efficient. Will definitely be an annual thing.”

ORS Clean focuses on exterior window cleaning. Exterior cleaning removes traffic pollution, hard water deposits, pollen, and grime that account for most of the visible dirt on Cupertino home windows. Text (408) 476-3891 to discuss your specific needs.
Cupertino's water supply — sourced from Santa Clara Valley Water District — 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 Cupertino homeowners benefit from window cleaning 1–2 times per year. Traffic pollution from Highway 280 and De Anza Boulevard, tech campus exhaust, seasonal pollen, and hard water sprinkler overspray accumulate quickly — especially on windows facing major corridors.
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.
We soften the sap and pollen with water and a gentle detergent first, then rinse with deionized water so nothing is scrubbed dry across the glass. The sticky residue lifts cleanly and the mineral-free rinse dries spot-free — much clearer than wiping sap around with a cloth.
Yes — screens are included on every Cupertino job, and we wipe the sills and frames. Cleaning the screens matters here because trapped pollen and dust otherwise wash straight back onto the fresh glass the next time it's damp.
