Essential Tools for Professional-Quality Window Cleaning
Professional window cleaners rely on specific tools that make the job easier and more effective. Here’s what you’ll need:
- Squeegee: The 12-inch size works best for most home windows
- Microfiber cloths: At least 3-4 for washing and drying
- Extension pole: For reaching high exterior windows safely
- Bucket with scrubber: For the initial wash
- Quality cleaner: Either commercial glass cleaner or homemade vinegar solution
| Tool | Purpose | Pro Tip |
|---|---|---|
| Squeegee | Streak-free drying | Wipe blade between strokes |
| Microfiber | Final polishing | Use separate cloths for inside/outside |
Step-by-Step Deep Cleaning Process
1. Prepare the Window Area
Remove curtains, blinds, or any window treatments. Dust the window frame, tracks, and sill thoroughly using a vacuum with a brush attachment. This prevents dirt from turning into mud when wet.
2. Clean Window Screens
Remove screens and wash with warm soapy water using a soft brush. Rinse thoroughly and let air dry completely before reinstalling. According to Good Housekeeping, 85% of window streaks come from dirty screens.
3. Wash the Glass
Apply your cleaning solution generously. For exterior windows, use a scrubber on a pole with a bucket of soapy water (1 tsp dish soap per gallon). Work in sections from top to bottom.
4. Squeegee Technique
Starting at the top, pull the squeegee straight down in one motion. Wipe the blade after each pass. Overlap strokes slightly to prevent missed spots.
Common Mistakes That Cause Streaks
Cleaning in Direct Sunlight
The sun causes cleaning solutions to dry too quickly, leaving residue. Clean windows early in the morning or on cloudy days for best results.
Using Paper Towels
Paper towels leave lint and don’t absorb enough moisture. Microfiber cloths are far superior for final polishing.
Neglecting Frames and Tracks
Dirty tracks transfer grime back to clean glass. Use an old toothbrush and hard water stain remover for stubborn buildup.
FAQs About Deep Cleaning Windows
How often should I deep clean my windows?
Most homes benefit from deep cleaning twice yearly – spring and fall. High-traffic areas may need quarterly cleaning. Spot clean smudges monthly.
What’s the best homemade window cleaner?
Mix 1/4 cup white vinegar, 1/4 cup rubbing alcohol, 1 tbsp cornstarch, and 2 cups warm water in a spray bottle. The alcohol helps prevent streaks while vinegar dissolves mineral deposits.

Yes. Over time, acidic pollutants and hard water minerals can etch glass permanently. Regular cleaning protects your window investment.
How do professionals clean windows so fast?
They use the right tools in the correct sequence: dust first, wash second, squeegee third. Proper technique eliminates rework.
What’s the best way to clean second-story windows?
Use an extension pole with a scrubber and squeegee attachment. Never stand on unstable surfaces. For very high windows, consider hiring professionals.
