What Professionals Use to Clean Windows Flawlessly

Cleaning windows might seem straightforward, but achieving a flawless, streak-free finish is more complex than it appears. Many struggle with smudges and streaks that stubbornly persist after cleaning, detracting from the clear, pristine appearance of the glass. In this guide, we will look into the professional techniques and tools used to clean windows flawlessly. From the proper cleaning solutions to specific tools and methods, you’ll learn how experts ensure that windows aren’t just cleaned but are left sparkling without a trace of residue. This approach not only enhances the aesthetic appeal of your windows but also improves visibility and light entry.

Cleaning Solutions

Professionals use a variety of cleaning solutions, each made to address different types of grime and window conditions. While household remedies like vinegar or all-purpose cleaner are popular for their accessibility, professionals often prefer specialized cleaning supplies. A favored choice is a dish soap solution, which effectively removes everyday dirt and grease without leaving streaks. For tougher grime, commercial window cleaning products are used, which are designed to dissolve stubborn residues and leave windows shining. This professional approach ensures that no matter the condition or type of dirt, the windows are treated with the most effective solution for spotless results.

Dish Soap Solution

The dish soap solution stands out for its effectiveness and safety on glass surfaces. Ideal for general cleaning, the perfect mix usually consists of a small squirt of dish soap in a bucket of warm water—enough to tackle grease and fingerprints without leaving suds behind. This solution should be applied using a soft cloth or sponge, ensuring the glass is covered evenly. The key is to avoid using too much soap to prevent residue, which can attract more dirt and cause streaking. Additionally, it’s important to rinse the glass thoroughly after wiping to remove any remaining soap, making the windows clearer and shinyr!

Windows Cleaning Tools

Professional window cleaners have an arsenal of specific tools designed to tackle various cleaning tasks effectively. Windows cleaning tools vary, from squeegees to washers and microfiber cloths, each serving a unique purpose. The choice of tool depends on the window’s size, the type of dirt, and the cleaning stage. Knowing which tool to use and when can significantly enhance the cleaning process, ensuring that every inch of the window is properly addressed. Using these tools properly not only optimizes cleaning but also prolongs the life of the windows by avoiding scratches and other damage that inappropriate tools might cause.


A squeegee is invaluable for removing water and soap from glass. It is also one of the window cleaning tools that are essential for avoiding streaks and ensuring a clear finish. It works best on oversized windows where long, smooth strokes can be applied. The technique involves dragging the squeegee across the window in a reverse-S pattern, which helps manage the moisture and leaves the surface dry and clear.


Washers, or strip applicators, are ideal for loosening and removing heavier soil from windows before squeegeeing. Their soft, non-abrasive fabric is perfect for applying soapy water to the glass without scratching. These window cleaning tools are particularly effective for quickly pre-cleaning large areas, for example, cleaning outside windows and making it easier to achieve streak-free results with the squeegee.

Cotton Towel or Microfiber Cloth

For the final touch, professionals often use cotton towels or microfiber cloths. These are crucial for wiping down the edges and corners where water collects, and streaks are most likely to form. Microfiber cloths are especially effective as they do not leave lint and can absorb a significant amount of moisture, ensuring the windows dry perfectly clear and streak-free. This step is essential for achieving the impeccable, professional finish that makes windows gleam brightly.  

In conclusion, achieving flawlessly clean windows requires more than just the standard approach; it demands a professional touch. Using the right combination of cleaning solutions, such as a dish soap mixture for general grime and specialized commercial products for tougher residues, is key. Also, selecting and applying various window cleaning tools—squeegees, washers, and microfiber cloths—play critical roles in the cleaning process. Each tool is specifically chosen based on the window’s size, the type of dirt, and the particular stage of cleaning. This strategic use of tools ensures thorough cleaning and avoids damage to the glass. By using these professional methods and techniques, anyone can achieve clean windows that are spotless, shiny, and streak-free.
