Why do window cleaners not use soap?
When it comes to cleaning windows most people think soap or soapy water is the way to go. But professional window cleaners don’t use soap for several reasons. In this article we’ll explain why do window cleaners not use soap and what professional window washers use to get streak free windows and a spotless finish.
Streak Free Windows
Streak free is key for professional window cleaning in Melbourne. Soap especially those with harsh chemicals or dish soap can leave residue behind that causes water spots or streaks on your glass surface. The goal is always a streak free finish that’s why professional cleaners avoid soap and use alternative methods that get streak free results.

Why Soap is Not the Best
- Soap Leaves Residue
Soap leaves residue especially if not rinsed properly with clean water. This residue attracts more dust making your windows dirty again quickly. Soapy water can also cause streaks that are hard to remove without excessive wiping or re-cleaning and often a streak free finish is impossible to achieve. - Soap Causes Streaking
When using soap especially liquid dish soap there’s a higher chance of water stains or water spots on your windows. This is because soap forms an oily film that causes streaking especially when exposed to sunlight. Professional window cleaning solution is designed to avoid this and leaves a Streak-Free Shine. - Soap Creates Excess Water
Soap produces a lot of foam which leaves too much water on the windows making it hard to remove all the excess water. This increases the risk of water spots especially when cleaning outdoor windows or high rise windows. Water-fed pole systems or window squeegees are used to remove the water efficiently so the windows stay clean and streak free. - Soap Damages Window Frames or Sills
Harsh soaps or soaps with added chemicals can damage window frames and window sills especially if they are wood or have a painted finish. Soapy water can leave behind an oily residue that attracts more dirt and grime to these surfaces. Professional window washers use a cleaning solution that’s safe for all parts of the window including the window tracks and window panes.

What Do Professional Window Cleaners?
- White Vinegar Solution
A simple vinegar solution (white vinegar and distilled water) is a great alternative to soap. This homemade window cleaner dissolves grease, dirt and grime and leaves no residue. When mixed right vinegar will clean windows without leaving water spots behind and give them a crystal clear finish. - Professional Window Cleaning Solution
Commercial window cleaners use a specialized window cleaning solution for specific types of windows including tinted windows. These solutions are designed to clean thoroughly without leaving streaks or harsh chemicals. They are safe for window sills, window tracks and window panes so all parts of the window are cleaned. - Microfiber Cloths and Lint-Free Cloths
Microfiber cloths are a window cleaning industry standard. These soft microfiber cloths pick up dirt and grime without leaving behind fibers. Using clean lint-free microfiber cloths will give you a streak free finish and work well with vinegar solution or window cleaning solution to get the best results. - Squeegees
Window squeegees are another must have tool for professional window cleaners. After applying the cleaning solution a window squeegee is used to remove the liquid from the glass in smooth strokes. This technique removes excess water and prevents streaking. - Water-Fed Pole Systems
For high rise windows or hard to reach areas water fed pole cleaning systems are used. These systems allow professional window cleaners to clean windows on the second story or higher without using ladders. They use clean water to rinse the windows thoroughly and avoid water spots and excess water.
