Nothing can quite compare to the appeal of spotless, streak-free windows in a home. They not only allow for an unobstructed view of the outside world but also let in natural light, making any room feel spacious and welcoming. However, achieving such an immaculate, streak-free finish can often seem like an uphill battle for many homeowners.

It’s no secret that professional window cleaning is an art form that requires a combination of specialised tools and techniques. These trade secrets have been honed over years of experience to ensure every window gleams with perfection. This guide will offer a peek into the world of professional window cleaning, sharing the industry’s best-kept secrets and cleaning tips, and teaching you how to achieve that perfectly clear, streak-free finish at home.

Essential Tools for Professional Window Cleaning

Professional window cleaning requires an arsenal of specific tools. Each one plays a critical role in achieving the pristine, streak-free finish that homeowners love.

1. Squeegee

A squeegee is a professional window cleaner’s best friend. With a rubber-edged blade, it efficiently removes water and cleaning solution from the window, leaving it perfectly clean and streak-free.

2. Microfibre Cloth

Microfibre cloths are a staple in professional window cleaning. They are highly absorbent, can attract and hold dirt particles, and don’t leave any lint behind on the glass surface.

3. Bucket

A bucket is essential for holding the cleaning solution. It should be large enough to easily dip a squeegee or scrubber inside.

4. Scrubber or Sponge

These tools are used to apply the cleaning solution to the window. They are capable of loosening dirt and grime, preparing the window for the squeegee.

5. Ladder

For hard-to-reach windows, a ladder is necessary. Professionals use sturdy, well-maintained ladders for safety.

6. Extension Pole

An extension pole can be fitted with a squeegee or scrubber, allowing the cleaner to reach high windows from the ground.

Expert Techniques for Streak-Free Windows

Beyond the tools, it’s the techniques that truly make a difference. Here are some professional window-cleaning secrets:

1. The S Method

Instead of wiping the squeegee in a back-and-forth motion, professionals use the S Method. This involves manoeuvring the squeegee in an S pattern, starting from the top. It ensures that the entire surface of the window is covered, and the cleaning solution doesn’t drip down.

2. Detailing the Edges

After squeegeeing the window, professionals detail the edges. They use a clean, dry microfibre cloth to wipe around the window’s edges to remove any leftover water or solution. This prevents drips and streaks from forming once the window dries.

3. Regular Cleaning

Regular cleaning is the best preventative measure against streaks. Dirt and residue accumulate on windows over time, and when mixed with water from rain or a sprinkler system, it can leave streaks. Regular cleaning prevents this build-up.

4. Cleaning on an Overcast Day

Professionals understand that the weather plays a vital role in window cleaning. Cleaning on a hot, sunny day causes the cleaning solution to dry too quickly on the glass, resulting in streaks. Overcast days provide the perfect condition for cleaning windows.


Despite knowing these professional secrets, achieving streak-free windows at home can be a significant task. It’s time-consuming and often requires a considerable amount of effort.
