Quick Answer
For streak-free windows: Clean on cloudy days, use a professional squeegee, work top-to-bottom, wipe the blade between strokes, and dry edges with microfiber. The secret is working quickly before the solution dries.
Living in San Diego means spectacular views—ocean panoramas, mountain vistas, and endless sunshine. But dirty windows can diminish all that natural beauty. Whether you're dealing with salt spray in La Jolla, pollen in the spring, or hard water spots from your sprinklers, clean windows make a dramatic difference in how your home looks and feels.
This guide teaches you the same techniques professional window cleaners use to achieve that crystal-clear, streak-free finish.
Professional Window Cleaning Process
Gather Supplies
You'll need a bucket, glass cleaner (or DIY solution of water, vinegar, and dish soap), squeegee, microfiber cloths, and a scrubber or sponge. For high windows, add an extension pole.
Remove Dust and Debris
Brush or vacuum window frames, tracks, and sills first. This prevents turning dust into muddy streaks when wet. Use a dry brush or vacuum attachment.
Clean Window Tracks
Spray tracks with cleaner and let sit. Use an old toothbrush or detail brush to scrub. Wipe out debris with paper towels. This step makes a huge difference in overall appearance.
Pre-Scrub Tough Spots
For bird droppings, tree sap, or dried-on residue, apply cleaner and let it soak for a minute. Gently scrub with a non-scratch pad. Never use abrasive materials that can scratch glass.
Apply Cleaning Solution
Wet the window completely with your scrubber or sponge. Work from top to bottom. Make sure the entire surface is wet—dry spots will streak.
Squeegee from Top to Bottom
Start at the top corner and pull the squeegee down in a straight line. Wipe the blade after each stroke. Overlap each pass slightly to avoid leaving lines.
Wipe Edges and Corners
Use a lint-free microfiber cloth to catch drips along edges and in corners the squeegee can't reach. This is the secret to truly streak-free windows.
Clean Frames and Sills
Wipe down frames with a damp cloth. Clean sills and any visible screens. Stand back and check your work from different angles to catch any missed spots.
San Diego Window Cleaning Tips
Salt Spray on Coastal Windows
Near the ocean, salt spray builds up quickly. Add a tablespoon of white vinegar to your cleaning solution to cut through salt residue. Coastal homes may need exterior cleaning monthly.
Hard Water Spots
San Diego's hard water leaves mineral deposits. For stubborn spots, apply undiluted white vinegar, let sit 5 minutes, then scrub gently. Avoid getting vinegar on window frames or screens.
Timing Is Everything
Clean windows during morning marine layer (before 10am) or late afternoon when windows are shaded. Midday sun causes streaking by drying solution too fast.
DIY Window Cleaning Solution
Professional-Grade Recipe:
- 2 cups warm water
- 1/4 cup white vinegar
- 1/2 teaspoon dish soap (no moisturizers)
Mix in a spray bottle or bucket. For extra-grimy windows, double the vinegar. This solution costs pennies and works as well as commercial cleaners.
Frequently Asked Questions
How often should I clean my windows?
For most San Diego homes, clean interior windows every 1-2 months and exterior windows quarterly. Coastal properties may need exterior cleaning monthly due to salt spray. Spring and fall are ideal times for thorough cleaning.
What's the best weather for window cleaning?
Clean windows on an overcast day or when windows are in shade. Direct sunlight causes cleaning solution to dry too quickly, leaving streaks. San Diego's morning marine layer often provides ideal conditions before 10am.
Why do my windows streak after cleaning?
Streaks are usually caused by cleaning in direct sun, using too much solution, using dirty equipment, or not drying properly. Use a squeegee with fresh solution and work quickly before the glass dries.
Can I use newspaper to clean windows?
The newspaper method is outdated—modern newspaper inks can leave residue. Use clean microfiber cloths or a professional squeegee instead. They're reusable and give better results.
