It takes more than soap and water to keep windows spotless and streak-free. To obtain those results, professional window cleaners use special tools or methods and window cleaning solutions. If you’ve ever viewed a window cleaner’s work and wondered what they’re using to get their windows so clean, we will explain exactly what do window cleaners use to wash windows. Whether you live in a high-rise office or a charming Victorian home, professionals have the right equipment to do the job quickly and safely. Read on to learn more.
Essential Tools Used by Professional Window Cleaners
Window cleaners count on a number of special tools to get the best results. Here’s a breakdown of their toolkit:

1. Squeegee:
The squeegee is the best tool to get streak-free windows. Professionals use high-quality squeegees with rubber blades to clean water and cleaning solutions efficiently. These blades are replaced often to stay fresh and every time they give a flawless finish.
2. Water-Fed Pole System:
Professionals use a water-fed pole system to clean high or hard to reach windows. Cleaners can use this tool to scrub and rinse windows from the ground with the help of extendable poles and a brush at the very end. Cleaning companies like Window Clean London use the Ionic Reach & Wash® System which uses purified water to deliver a spot-free shine.
3. Microfibre Cloths:
Microfibre cloths are important for wiping away residue and polishing windows. They are very soft or super absorbent and delicate. They are great for glass and window frames.
4. Scraper or Blade:
A scraper or razor blade is for windows with stubborn dirt and paint splatters or stickers. This tool is used carefully to remove tough debris without scratching the glass.
5. Bucket with Holster:
Cleaning solutions and tools are kept in a bucket and most frequently this bucket has built-in holster. A holster makes it easy to get to the squeegee or scrubber to clean faster.
6. Ladders and Harnesses:
Most high windows will be done with water fed poles but sometimes it is necessary for a ladder or safety harness to be used. Professionals use these to reach tricky areas safely.

Cleaning Solutions: What Do Professionals Use?
The cleaning solution is just as important as the tools. Here’s what window cleaners use:
1. Purified Water:
Purified water is a game-changer in window cleaning. Unlike tap water, it contains no minerals or impurities, which means it leaves no spots or streaks behind. Systems like the Ionic Reach & Wash® make sure that windows are rinsed with the purest water possible.
2. Dish Soap and Water:
Professionals use a simple mix of dish soap and water for everyday cleaning. It’s cheap or works fast and can easily remove the dirt and grease. The trick is using just the right amount of soap so there’s no residue.
3. Eco-Friendly Cleaning Solutions:
Environmentally conscious companies use biodegradable and non-toxic cleaners. These solutions are safe for both the environment and the surfaces being cleaned.
4. Vinegar and Water:
Natural window cleaning uses vinegar and water mixed. Vinegar is a good grime breaker and glass shiner. But this is especially popular for residential jobs where customers want natural cleaning products.
Step-by-Step Process of Professional Window Cleaning
Now that we know the tools and solutions let’s look at how professionals use them for spotless results:
Step 1: Preparation: Window cleaners begin by looking at the windows and sorting out what tools they will need. The first thing they often do is to brush off and rinse away loose dirt and dust.
Step 2: Applying Cleaning Solution: The cleaning solution is applied with a scrubber or a microfibre cloth. Professionals use smooth and circular motions to break down grime and dirt. They focus on corners and edges.

Step 3: Using a Squeegee: A squeegee is used to remove the cleaning solution. They start at the top of the window, dragging the blade down in straight lines or wiping it after each stroke. This technique guarantees streak-free windows.
Step 4: Rinsing and Drying: A water-fed pole system is used to spray purified water to the high windows. Then this rinses off any remaining solution. Smaller jobs use a dry microfibre cloth to polish the glass.
Step 5: Cleaning Frames and Sills: The cleaners don’t stop at the glass. Finally, the frames and sills are wiped down and any leftover cleaning solution is removed so that the whole window is spotless.
Specialized Equipment for High-Rise and Victorian Homes
Professional cleaners use advanced equipment tailored to different property types:
- High-Rise Buildings: Water-fed poles and safety harnesses are essential for towering office blocks. These allow cleaners to work safely from the ground or using rope access techniques.
- Victorian Homes: Traditional sash windows found in Victorian homes require a gentler approach. Professionals use soft brushes and eco-friendly solutions to preserve the delicate frames while delivering streak-free results.
Why Do Professionals Use Purified Water?
Purified water is a hallmark of professional window cleaning. But why is it so effective? Regular tap water contains minerals and impurities that can leave spots on glass. Purified water, on the other hand, has all impurities removed, allowing it to dry without leaving any marks. It’s especially effective for high windows, where manual drying isn’t possible. Companies like Window Clean London invest in systems like the Ionic Reach & Wash®, which filters water to ensure the cleanest finish possible.
