Window Cleaning Detergent

Professional window cleaners often rely on cleaning solutions designed to dissolve dirt, grime and residue from windows without leaving unsightly streaks behind.

Extension Poles

When it comes to cleansing windows in hard-to-reach areas, professionals utilize extension poles and attachments. These poles enable them to access upper-floor windows without requiring the use of ladders.

Razor Blades/Scrapers

For tackling debris, such as paint splatters, adhesive residue or other contaminants, on window glass surfaces, razor blades or scrapers come into play as removal tools.

It’s essential to be cautious when cleaning the glass surface to avoid scratches.

Waterfed Pole Systems

Professionals sometimes rely on water-fed pole systems to clean windows on the outside. These systems use water pumped through a pole with a brush attachment at the end. The brush gently scrubs the glass while the pure water effectively rinses dirt and other contaminants.

T-bars and Washer Sleeves

Professionals use T-bars and washer sleeves to apply cleaning solutions to the window glass. The washer sleeve helps loosen and remove dirt from the surface.


While professionals prioritize safety and try to avoid using ladders whenever possible, there are instances where they become necessary for reaching windows that are out of reach with extension poles.

Drying Mats or Pads

After washing and squeegeeing the windows, professionals may employ drying mats or pads to remove all remaining moisture, leaving behind dry windows.

It’s important to note that professional window cleaners often have their preferred brands of tools and cleaning solutions based on their experience and the specific challenges posed by each job. Employing techniques and paying attention to detail are factors in achieving top-notch results.

4. Prepare Your Cleaning Solution

Follow the manufacturer’s instructions, for mixing the window cleaning detergent with water. Be mindful not to use an amount of detergent as it can leave behind residue.

5. Wash Those Windows

 Dip the washer sleeve into the window cleaning solution, ensuring liquid is wrung out. Use the T bar to apply the solution onto the window glass, gently scrubbing to loosen dirt. Begin at the top of the window. Work your way down.

Here’s a step, by step guide on how to clean windows 

1. Start with the squeegee technique

Begin at the corner of the window and pull the squeegee down in a line. Make sure to wipe the blade with a cloth after each pass. Overlapping each squeegee stroke will help avoid streaks.

2. Don’t forget about edge wiping

Use a cloth to wipe along the edges and corners of the window where the squeegee can’t reach. This helps prevent water from pooling and causing streaks.

3. Check for any remaining spots

After using the squeegee, inspect the glass for any spots or streaks that might still be present. If you find any spots, use a microfiber cloth to buff them away gently.

4. Dealing with stains

If you come across paint splatters, stickers or other harsh residues you can carefully lift them off using a razor blade or scraper. Remember to keep the blade clean and at an angle to avoid scratching.

5. Window cleaning

For washing windows, consider using a water-fed pole system that includes a brush for scrubbing and purified water for rinsing away dirt. This method is beneficial for reaching windows that are difficult to access.

6. Finish off by drying and buffing

Once you’ve completed cleaning, use a cloth or drying mat/pad to gently wipe around the edges and corners of the glass, ensuring it is completely dry and free of any remaining moisture.

Make sure to dry the windows to ensure all moisture is eliminated and streaks are prevented.

7. Clean frames and window sill

Take some time to clean the window frames and sills well. Use a cloth to wipe any residue from the cleaning solution or dirt that may have built up over time.

Always remember that practice leads to perfection. The more you use these techniques to clean your windows, the better your results will be. Pay attention to detail, work in a manner and take your time to achieve windows free of streaks and sparkling clean.
