Windows cleaning

Cleaning windows might seem like a straightforward task. A splash of water, a dab of soap, and a bit of elbow grease, right? Well, not quite, especially if you’re talking about the pros. Professional window cleaners have a method to their magic, ensuring your panes are not just clean, but sparkling. So, what are their secrets? Buckle up, as we delve deep into the arsenal of a professional window cleaner.

The Importance of Cleaning Solutions

The Right Soap Matters

The regular dish soap might work for your kitchen chores, but when it comes to windows, professional cleaners use specially formulated solutions. Why? These are designed to cut through the toughest of grime without leaving streaks.

pH Balanced is the Way

Ever wondered why some cleaning solutions make windows spotless while others leave unsightly spots? The key lies in the pH balance. A neutral pH ensures no harmful reactions with the glass or frame materials, keeping them pristine.

Eco-friendly Options

Today, the shift is towards eco-friendliness. Many professionals are using biodegradable and environmentally safe cleaning agents. It’s not just good for Mother Earth but also for those living inside the house.

Homemade Brews

Surprisingly, some pros swear by homemade solutions, like a mix of water, vinegar, and dish soap. It’s all about finding that perfect concoction that works wonders for them.

The Magic of Squeegees

Not Just Any Squeegee

You might be tempted to grab any squeegee off the shelf, but pros know that quality matters. A high-quality squeegee ensures a streak-free finish, and its rubber blade can be replaced when it wears out.

The Technique

It’s not just about dragging it down the window. There’s an art to it! The angle, the pressure, the direction—all of it counts.

Size Does Matter

Depending on the window size and shape, professionals have a range of squeegees at their disposal. From small ones for tight corners to large ones for expansive panes, they’ve got it all.

Maintenance is Key

Cleaners ensure that the squeegee rubber is always clean and sharp. A nicked or dirty blade can leave unwanted marks.

Scrubbers and Brushes

Loosening the Grime

Before using a squeegee, pros use scrubbers or brushes to agitate and loosen the dirt. It makes the subsequent squeegeeing process more effective.

Specialty Brushes

There are brushes specifically designed for window frames, tracks, and sills. They ensure every nook and cranny is attended to.

Soft Bristles vs. Hard Bristles

Depending on the type of grime, professionals choose their brushes. Soft for general dust and hard for stubborn stains.

Frequency Matters

Regular scrubbing can prevent dirt from hardening, making the cleaner’s job easier during the next round.

Safety Equipment

Ladder Safety

For those hard-to-reach windows, ladders are indispensable. But safety first! Professionals ensure their ladders are stable and in good condition.

Harnesses and Belts

For skyscrapers and high-rise buildings, window cleaners often use harnesses to prevent any mishaps. Safety is paramount.

Protective Gear

From gloves to protect their hands from chemicals to sunglasses for the glare, the pros are always geared up.


A good grip is crucial. Hence, professional cleaners often wear shoes with non-slip soles, especially when working at heights.

Water-Fed Pole Systems

Pure Water Cleaning

This system uses deionized or purified water. When this water evaporates, it leaves no residues, ensuring a crystal-clear window.

Extended Reach

Water-fed poles can reach up to 70 feet! That’s some serious reach without needing a ladder.

Brush Attachments

The poles often come with brush attachments, making it easier to scrub off dirt while rinsing simultaneously.


As there’s no detergent used, it’s an environmentally friendly method. Plus, the reduced risk of falling from heights is a bonus!

Miscellaneous Tools

Detailing Towels

For wiping off excess water or detailing corners, these come in handy. They’re lint-free and super absorbent.

Blades and Scrapers

Got some paint or sticker residue on your window? These tools help get rid of them without scratching the glass.

Extension Poles

For that extra reach without a ladder, extension poles are invaluable.


It sounds funny, but it’s a lifesaver. It holds all the essential tools, ensuring the cleaner can work efficiently without going back and forth.

The Right Technique is Everything

Top to Bottom

Always start at the top and work your way down. It ensures dirty water doesn’t ruin areas you’ve already cleaned.


For wider windows, the side-to-side squeegee method is preferred. It ensures an even clean across the entire pane.


It’s not just about the tools but how you use them. Pros maintain a consistent pressure and speed.

Regular Cleaning

It’s easier to clean a slightly dirty window than one that hasn’t been cleaned in months. Regular cleaning ensures longevity and clarity.


While you might be tempted to DIY, understanding the tools and techniques professionals use can give you a newfound appreciation for their craft. It’s not just about making windows shine; it’s about ensuring their longevity, enhancing visibility, and elevating the overall aesthetic of a space.
