Summer in the Snoqualmie Valley gives Duvall homes some of the best natural light of the year, but that light also reveals every streak, smudge, and dusty screen. After a spring of river-valley pollen and pale, wet-season glass, most windows are working against you rather than for you. Cleaning them is one of the simplest, highest-impact things you can do before the long summer evenings settle in.
Start with the screens, not the glass
Screens trap a season's worth of farmland pollen and fine valley dust, and washing the glass first just means that grime rinses right back onto it. Pop each screen out, brush it down, and rinse it gently with a hose on a low setting before setting it in the sun to dry. Homes closer to the fields around Old Town and the open ground near Rio Vista tend to collect the most pollen, so plan a little extra time there.
For the glass, skip the midday heat
Direct summer sun dries cleaner too quickly and leaves streaks, so aim for morning or early evening. A simple solution of water with a splash of vinegar and a microfiber cloth handles most Duvall windows, and a squeegee makes quick work of larger picture windows that look out toward Big Rock. Work top to bottom, and finish edges and corners where pollen likes to cake.

Don't forget the tracks and sills
This is where valley dust and dead bugs accumulate, and it's the part homeowners most often skip. A dry brush followed by a damp cloth clears them out and helps windows slide freely all season.
The detail people notice most
Clean windows are also the detail people notice most when a home is on the market or hosting guests, and they're a natural add-on to a full deep clean. If you'd rather spend your evenings at the Thursday farmers market than balancing on a step stool, our team can handle interior windows, screens, tracks, and sills as part of a summer deep clean.

Frequently Asked Questions
When is the best time of day to clean windows in summer?
Morning or early evening. Direct midday sun dries cleaning solution too quickly and leaves streaks, so work the glass while it's cool for a streak-free finish.
