Can I Clean My Windows with Tap Water?

Valley Window Care guarantees flawless Purified Window Cleaning in De Pere, WI, and the surrounding Fox Cities. Using standard domestic tap water actively ruins exterior glass by leaving an immensely hard film of highly baked-in calcium and heavy iron oxidation.

The Chemistry of Bad Window Cleaning

Ripping a hardware store squeegee across your second-story Fox Valley home immediately after spraying a cheap garden hose guarantees an entirely botched job.

Tap water in Northeast Wisconsin is famously intensely hard. When you spray incredibly dense mineral water on heavily heated exterior panes, the immense liquid evaporates perfectly, but the absolute heavy metal deposits physically cannot. They remain intensely glued to the pores of the glass windows, forming a massive white haze.

Avoid Common DIY Detriments

• Blue Window Soap Disaster: Windex contains incredibly harsh heavy ammonia absolutely designed strictly for interior domestic glass. Spraying it outside actively smears the heavy road salt deeply into a highly dense glaze.
• Micro-Scratches on the Sills: Using filthy rags perfectly scrapes the incredibly hard invisible sand particles entirely across the incredibly smooth glass, forming millions of tiny, permanent destructive scratches.
• The Ladder Wobble: Physically climbing an incredibly unsafe wet metal ladder to hopelessly dab at a stubborn tap water spot on your massive De Pere siding is a terrifying, highly unnecessary gamble.

Frequently Asked Questions About Cloudy Windows

Can professional pure water permanently fix twenty years of absolutely massive hard calcium etching? No. If the massive white spots have aggressively physically dissolved the absolutely smooth top layer of your exterior architectural glass over decades, standard Fox Valley window cleaning operations cannot heal the deep structural pitting.

Does heavily raining the day after you magically clean them ruin the view? Never. Rainwater is literally naturally pure H2O precisely evaporated from the Great Lakes. Rain itself is completely spotless; it only streaks when it aggressively hits entirely dirty windows and mixes intensely with the massive surface dust. Because we leave your windows absolutely surgically clean, the heavy Green Bay spring rain effortlessly glides down the glass completely spotless.
