Snapshot:
- What causes spots? Minerals from sprinklers/overspray bond to glass as water dries.
- Why the haze? Dust + drizzle + pollen create films that scatter light.
- DIY that works: vinegar soak, gentle pads, microfiber—avoid harsh abrasives.
- When to call a pro: visible mineral crusts, etched “ghosting,” multi‑story access, post‑construction debris.
- Prevention: re‑aim sprinklers, rinse during dry spells, clean on a schedule.
Understanding the Build‑Up
Hard water stains are the mineral residue (calcium, magnesium, others) left after water evaporates. Fresh deposits sit on the surface; over time they can bond more firmly and even lead to etching—microscopic damage that looks like a foggy ghost image. Combine that with pollen and fine dust, and you get windows that never look truly clear.
Where it comes from locally:
- Sprinkler overspray or hose water hitting glass.
- Unrinsed garden mist drying in afternoon sun.
- Windblown dust sticking to damp panes.
- Tree sap and organic residue around landscaping.
Safe DIY Methods (That Don’t Scratch)
- Vinegar soak: spray white vinegar, let dwell 3–5 minutes, gently wipe; repeat as needed.
- Non‑scratch pad: light pressure only; test a corner first.
- Rinse & dry: finish with clean water and a microfiber towel to prevent streaks.
- Inside smudges: a few drops of dish soap in warm water + squeegee = streak‑free.
Avoid: steel wool on coated/tempered glass, powdered abrasives, pressure washers on seals, or scraping without training—these can permanently mark glass
When Professional Help Saves the Day
- You see white crusts or rings that don’t budge after a few DIY cycles.
- Glass shows ghosting in low‑angle light—possible etching.
- Panes are high or difficult to reach safely.
- There’s construction dust/paint on the exterior.
We use controlled mineral removers, specific pads, and water‑fed poles to flush away residue. If etching is present, we’ll explain options clearly—sometimes we can improve the look substantially; sometimes replacement is the honest answer.
Prevention: The Real Money Saver
- Aim sprinklers away from windows and adjust arc/throw length.
- Create a buffer zone with landscaping that doesn’t spray soil onto glass.
- Rinse during long dry spells to knock off dust and salts.
- Stay on a schedule: exterior every 2–3 months, interior every 3–6 months.
- Clean screens—dirty screens re‑contaminate glass quickly.
Seasonal Checklist for Puget Sound Homes
- Early spring: deep clean after winter storms; check tracks and weep holes.
- Late spring: pollen round—wash screens and exteriors.
- Summer: monthly quick rinse if near busy roads or sprinkler zones.
- Early fall: get glass pristine before the rainy season.
- Holidays: consider a pre‑light install clean so decorations pop in photos.
Myths vs. Reality
- Myth: “Rain makes windows dirty.” Reality: rain reveals existing films. Clean glass actually stays clearer after showers.
- Myth: “Newspaper is best.” Reality: modern inks/coatings can smear—use microfiber.
- Myth: “Any pad is fine.” Reality: the wrong pad can scratch permanently.
