We deionize the water completely first, removing the calcium and magnesium that cause Santa Clara's notorious hard-water spotting.
A soft brush fed with that pure water lifts the mineral film and urban dust off each pane without scratching the glass.
A deionized rinse sheets the dissolved film and grime off and dries with nothing left behind — the key to beating hard-water haze.
Screens and frames are cleaned on every job at no extra cost, so settled dust doesn't rinse back onto the clear glass.
In hard-water Santa Clara a squeegee is almost self-defeating. Every drip of the mineral-heavy local water dries into the chalky spotting the town is known for, and the soap left behind holds urban dust and pollen — so ordinary washing just resets the haze.
Deionized water is the only real cure for that. With all the minerals filtered out, it dissolves the existing hard-water film and then dries leaving nothing behind to spot or cloud the glass — the one method that actually breaks Santa Clara's cloudy-window cycle instead of feeding it.
Upper-floor windows are reached with a water-fed pole from the ground, no ladder on the house. The purified water gives the high panes the same genuinely spot-free finish as the windows at eye level.
If your Santa Clara windows look permanently cloudy, it's almost always hard water. Santa Clara's mineral-heavy supply is rough on glass: every time sprinkler overspray or a quick rinse dries on the window, it leaves calcium and magnesium behind as a chalky, light-scattering film. Add the everyday urban dust and pollen and the panes look dull year-round.
That mineral spotting is the one thing ordinary cleaning can't beat — soap and tap water dry into more of the same film, so the haze is back within days, and deposits left for years bond harder and start to etch the glass. A rag just smears it.
We clean with deionized water that has the minerals removed, so it dissolves the existing hard-water film and then dries with absolutely nothing left to spot the glass — no chemicals, screens included. 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, hard water deposits, pollen, and grime that account for most of the visible dirt on Santa Clara home windows. Text (408) 476-3891 to discuss your specific needs.
Santa Clara'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 Santa Clara homeowners benefit from window cleaning 1–2 times per year. Traffic pollution from the Central Expressway and Lawrence Expressway, tech campus construction dust, seasonal pollen, and hard water sprinkler overspray accumulate quickly on window glass.
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 Santa Clara's water is hard — every rinse or sprinkler mist dries into a mineral film, and ordinary cleaner leaves its own residue on top. Only mineral-free (deionized) water breaks that cycle: it dissolves the film and dries completely clear. Years-old etched deposits may need an extra restoration pass, which we'll flag.
We remove them fully, and the best prevention is keeping sprinkler and irrigation overspray off the glass — that's the source of most Santa Clara window spotting. We'll point out which heads are hitting your windows so you can adjust them; after that the glass stays clear much longer.
