Window Cleaning After Rain in San Diego
Rain in San Diego often leaves windows covered in spots, streaks, and mineral buildup. While it might seem like rainwater would rinse windows clean, it actually carries dust, pollutants, and minerals that stick to glass, blocking your view and dulling your home’s appearance.
Cleaning your windows after a storm not only restores clarity and brightness but also helps protect your property value. Thanks to San Diego’s mild weather, the period right after rainfall is the ideal time to get your windows cleaned before the next storm hits.
San Diego’s Mediterranean climate features mild, wet winters and warm, dry summers. Most of the city’s 10 inches of annual rainfall occurs between November and March, often during powerful systems known as atmospheric rivers.
Weather factors that affect windows:
Dry Months (April–October): Dust, salt spray, and pollutants accumulate on glass.
Morning Fog & Sun: Cause water spots and mineral deposits, especially near the coast.
Storms & Winds: Drive rain, mud, and debris directly onto windows, leaving streaks once dry.
Periods of drought intensify these effects—dust and ash from wildfires settle on glass, creating residue that’s difficult to remove once mixed with rainwater.
Residential Cleaning
Remove Loose Debris: Start by brushing away dirt, sand, and cobwebs from frames and screens.
Prepare Cleaning Solution: Mix mild dish soap with warm water, or combine 1 part vinegar with 4 parts water for a streak-free finish.
Squeegee Technique: Begin at the top corner and pull across in straight lines, wiping the blade after each pass.
Spot Treatment: Use rubbing alcohol on microfiber cloths for stubborn hard water stains.
Clean Tracks and Sills: Use a small brush and the same cleaning solution to remove collected dirt.
High-Rise & Commercial Buildings
Use only trained professionals with OSHA-approved safety gear and insurance.
Avoid cleaning during wind speeds above 15 mph.
Use extension poles or internal reach tools to minimize risk.
Never clean from ladders on wet or uneven ground.
Oil Stains: Apply a degreaser or baking soda paste for 10–15 minutes, then rinse.
Tree Sap: Use rubbing alcohol or hand sanitizer on a cloth to dissolve residue.
Mud & Fine Debris: Rinse first with a garden hose before scrubbing.
Stuck-On Grime: Use plastic scrapers, not metal, to avoid scratching glass.
Gutters & Driveways
Remove debris and check drainage to prevent flooding.
Pressure wash driveways to lift oil stains, mud, and organic buildup.
Solar Panels & Roofs
Clean solar panels to restore up to 30% energy efficiency.
Use non-abrasive cleaning methods for tile or asphalt roofs.
Inspect for storm debris, algae, or damage after heavy rainfall.
Decks, Fences, & Stucco Surfaces
Use gentle pressure washing on wood.
Apply specialized cleaners to remove mildew or stains from stucco.
Seal concrete surfaces to prevent future spotting and staining.
How soon should I clean windows after a San Diego rainstorm?
Within 2–3 weeks after significant rainfall. Coastal homes may need more frequent cleanings due to salt exposure.
What’s the best solution for removing rain spots?
Equal parts white vinegar and distilled water work best. Use microfiber cloths and a squeegee for streak-free results.
Do coastal homes need special care?
Yes. Salt deposits can etch glass if left too long. Hard water stains are also common due to mineral-rich rainwater.
What does post-rain professional window cleaning cost?
1-story homes: $125–$200
2-story homes: $200–$350
Individual windows: $8–$15 each
Seasonal cleaning packages often save 15–20%.
How can I prevent water spots after rain?
Apply a rain-repellent product like Rain-X for windows to create a hydrophobic layer. Remove and clean screens regularly, and use a squeegee to dry windows after showers.
Is it safe to clean windows right after a storm?
Wait until the weather is calm and surfaces are dry. Wear non-slip shoes and avoid using ladders on wet ground. Always ensure good ventilation and avoid mixing cleaning chemicals.
San Diego’s mix of salt air, dust, and unpredictable rain makes post-storm window cleaning essential. Whether you’re in La Jolla, Pacific Beach, Mission Beach, Del Mar, or anywhere across the county, Coastal Clarity helps restore your view safely and effectively.
