How to Clean Windows as a Professional

Introduction: Why Mindset Still Matters

"Time is money." You've heard it before. But when cleaning windows professionally, the phrase becomes more than just a cliché — it becomes the foundation for how to work smarter. Unlike hourly workers, professional window cleaners are paid for results, not time. The faster and cleaner the job, the higher the earnings — assuming quality stays high.

The Technique: Professional Windowcleaner Craftsmanship That Saves Hours

What separates a professional that learned how to clean windows as a professional from an amateur is often not effort — it’s technique. Many cleaners still use 30cm tools for 1x1m windows, which wastes time. Upgrading to a 60cm squeegee alone doubles your speed. Combine this with two-handed cleaning, and your efficiency skyrockets.

We've seen cleaners cut full workdays from 8 hours to just over 3 hours. Not by rushing, but by refining technique after we learned them how to clean windows as a professional.

Breaking Old Windowcleaner Habits

So why isn’t everyone doing this? Three main reasons:

1. Inertia: Most who try larger tools only use them for a total of 30 hours, despite having 40,000+ hours with smaller gear the last 20 years.
2. Bad muscle memory: Just like switching to faster squeegee, you’ll struggle at first. It’s not worse — it’s unfamiliar.
3. Weak training systems: Most cleaners are trained by others who were never properly trained themselves. Bad habits compound.

Our analysis of 300 training setups found that most cleaners receive just 6 hours of real instruction (direct one-on-one training where the trainer is not focused on cleaning windows themselves.). That’s not enough to master professional techniques or new tools.

Build Good Habits from Day One

Success in professional window cleaning comes from building the right habits early:

• Use 60cm+ tools
• Clean with both hands at once (washer + squeegee)
• Avoid micro-delays and wasted movement
• Learn how to structure your entire workflow

These techniques is the answer to how to clean windows as a professional and offer a 4x speed boost — not in theory, but in real-world results. The biggest gains come from simply changing how you hold your tools and how you move from window to window.

Two-Handed Cleaning: The Pro Technique

Most cleaners wash with one hand and switch to the squeegee with the other. But professionals learn to clean with both hands simultaneously:

• Left hand: washer
• Right hand: squeegee

This continuous motion cuts time nearly in half. It takes practice, but within weeks, it becomes automatic and effortless — and your results improve dramatically.
