What Do Professionals Use To Clean Outside Windows?

Windows are the eyes of a building, allowing light and views of the outside world to filter in. However, maintaining their clarity and cleanliness can be a daunting task, especially when it comes to cleaning outside windows. In this guide, we'll delve into the techniques and tools that professionals use to achieve sparkling results and ensure your windows shine bright, rain or shine.

Essential Tools for Outdoor Window Cleaning

When it comes to cleaning outside windows like a pro, having the right tools at your disposal is essential. Here's a deeper dive into each of these tools and their importance:


Safety should always be the top priority when cleaning outdoor windows, especially those on upper floors. Ladders provide access to hard-to-reach areas, allowing you to clean windows at various heights. It's crucial to choose the right ladder for the job, ensuring it's stable, properly positioned, and capable of reaching the desired height safely.


Arguably the most important tool in a professional window cleaner's arsenal, squeegees are used to remove water and cleaning solution from the glass surface. They consist of a rubber blade attached to a handle, which effectively removes dirt, grime, and streaks, leaving behind a streak-free shine. Professionals often use squeegees of various sizes to tackle different window sizes and shapes.

Extension Poles

For windows located on upper floors or in awkward positions, extension poles are indispensable. These telescopic poles can be adjusted to the desired length, allowing you to reach high windows without the need for precarious maneuvers on ladders. They often come with attachments for squeegees or scrubbers, further enhancing their versatility.

Scraper Blades

Stubborn stains, paint splatters, or hardened debris may require more than just a squeegee to remove. Scraper blades, typically made of stainless steel, are used to gently scrape away tough residues from the glass surface without causing damage. It's important to use caution when using scraper blades to avoid scratching the glass.

Microfiber Cloths

While squeegees do an excellent job of removing water and cleaning solution, microfiber cloths are used for detailing and final touches. These soft, lint-free cloths absorb any remaining moisture and help polish the glass to a sparkling finish. Microfiber cloths are also gentle on the glass surface, reducing the risk of scratches or streaks.

By equipping yourself with these essential tools and understanding their proper usage, you can tackle outdoor window cleaning tasks with confidence and achieve professional-quality results. Always prioritize safety, choose high-quality tools, and invest in proper training to ensure effective and efficient window cleaning operations.

Cleaning Solutions and Techniques

Achieving spotless windows on the outside requires not only the right tools but also effective cleaning solutions and techniques. Let's delve deeper into each aspect:

Homemade Solutions

Many professionals opt for homemade cleaning solutions due to their effectiveness and eco-friendliness. One popular recipe involves mixing equal parts of distilled white vinegar and water in a spray bottle. Vinegar's acidity helps dissolve dirt and grime, leaving windows streak-free. Alternatively, a solution of mild dish soap and water can also be effective for general cleaning tasks. These homemade solutions are cost-effective and safer for the environment compared to commercial cleaners.

Commercial Cleaners

For more stubborn stains or heavily soiled windows, commercial cleaners can provide the extra cleaning power needed. These cleaners come in various formulations, including concentrates that can be diluted with water and ready-to-use sprays. Look for cleaners specifically designed for outdoor use, as they often contain ingredients that help break down dirt and grime effectively. It's essential to follow the manufacturer's instructions and safety guidelines when using commercial cleaners, especially when working at heights.

Techniques for Streak-Free Cleaning

Even with the right cleaning solution, achieving streak-free windows requires proper technique. Start by wetting the window with your chosen cleaning solution, ensuring thorough coverage. Next, use a squeegee to remove the solution, starting from the top and working your way down in a series of overlapping strokes. Wipe the squeegee blade with a clean cloth after each pass to prevent streaks. Finish by using a dry microfiber cloth to wipe any remaining moisture from the edges of the window and frame.

Before applying any cleaning solution, it's essential to prepare the window surface properly. Use a hose or bucket of water to wet the window thoroughly, loosening dirt, dust, and debris. This initial rinse helps prevent scratching the glass during cleaning and ensures better results. For particularly dirty windows, consider using a soft-bristle brush or sponge to agitate stubborn spots before applying the cleaning solution.

After cleaning, rinse the window thoroughly with clean water to remove any residual cleaning solution. This step helps prevent streaks and ensures a crystal-clear finish. Pay special attention to the edges and corners of the window, where residue is more likely to accumulate. Finally, use a dry microfiber cloth to wipe the window dry, starting from the top and working your way down. This extra step helps eliminate water spots and ensures a flawless shine.

By mastering these cleaning solutions and techniques, you can achieve professional-quality results when cleaning outside windows. Whether using homemade solutions or commercial cleaners, proper preparation, application, and finishing are essential for streak-free, sparkling windows that enhance the appearance of any building.

Safety Measures and Precautions

Ensuring safety during outdoor window cleaning is paramount to avoid accidents and injuries. Here's a detailed exploration of the safety measures and precautions professionals take:

Proper Ladder Usage

When using ladders to access higher windows, it's crucial to follow safety protocols rigorously. This includes selecting the right ladder for the job, ensuring it's stable on a flat surface, and extending it to the appropriate height. Professionals often use ladder stabilizers or stand-offs to increase stability and prevent damage to the building's exterior. Additionally, maintaining three points of contact at all times while climbing and descending helps reduce the risk of falls.

Weather Considerations

Weather conditions can significantly impact the safety and effectiveness of outdoor window cleaning. Avoid cleaning windows on windy or rainy days, as these conditions can increase the risk of accidents and make it challenging to achieve streak-free results. If rain is forecasted during a scheduled cleaning session, reschedule the task for a clearer day to ensure optimal safety and cleanliness.

Protective Gear

Personal protective equipment (PPE) is essential for safeguarding against potential hazards during window cleaning. This includes wearing gloves to protect hands from chemicals and sharp objects, as well as safety glasses or goggles to prevent eye injuries from splashes or debris. Additionally, wearing non-slip footwear with good traction helps maintain stability on ladders and slippery surfaces, further reducing the risk of accidents.

Bystander Safety

Before beginning any outdoor window cleaning task, it's essential to ensure the safety of bystanders and passersby. Erect warning signs or barriers to alert others to the cleaning activity and prevent them from walking underneath windows during the cleaning process. Communicate with residents or occupants of the building to inform them of the cleaning schedule and any precautions they should take to avoid accidents.

Equipment Maintenance

Regular maintenance of cleaning equipment, including ladders, extension poles, and safety harnesses, is crucial for ensuring their safe and effective operation. Inspect equipment before each use for signs of wear, damage, or defects, and address any issues promptly. Properly store equipment when not in use to prevent deterioration and prolong its lifespan. Additionally, follow manufacturer guidelines for maintenance and servicing to keep equipment in optimal condition.

By prioritizing safety measures and precautions, professionals can mitigate risks and ensure a safe working environment during outdoor window cleaning tasks. From proper ladder usage and weather considerations to the use of protective gear and equipment maintenance, implementing these safety protocols is essential for preventing accidents and injuries in the workplace.

Maintenance Tips for Prolonged Cleanliness

Maintaining the cleanliness of outdoor windows goes beyond just the cleaning process itself. Here are additional maintenance tips that professionals follow to ensure windows stay clean and clear for longer periods:

Regular Cleaning Schedule

Establishing a consistent cleaning schedule is essential for preventing dirt and grime buildup on outdoor windows. Depending on factors such as location, climate, and surrounding environment, windows may require cleaning anywhere from monthly to quarterly intervals. By staying proactive and adhering to a regular cleaning routine, you can prevent the accumulation of dirt and maintain the aesthetic appeal of your windows.

Inspecting for Damage

Regular inspections for damage such as cracks, leaks, or damaged seals are crucial for preserving the integrity of outdoor windows. Perform visual inspections periodically to identify any signs of wear or deterioration and address them promptly. Repairing small issues early can prevent them from escalating into more significant problems, prolonging the lifespan of the windows and ensuring their continued functionality.

Gutter Maintenance

Gutters play a vital role in directing water away from the building's exterior, including windows. Clogged gutters can lead to water overflow, causing debris and dirt to splash onto windows and create unsightly stains. Regular gutter maintenance, including cleaning out leaves, twigs, and other debris, helps prevent this buildup and reduces the likelihood of windows becoming dirty prematurely.

Trimming Trees and Shrubs

Overhanging branches and foliage can deposit debris, pollen, and sap onto outdoor windows, contributing to their soiling. Regularly trimming trees and shrubs near windows helps minimize the accumulation of debris and reduces the frequency of window cleaning required. Additionally, maintaining vegetation at a distance from windows enhances air circulation and natural light, further promoting cleanliness and clarity.

Sealing and Insulating

Properly sealing and insulating windows is essential for preventing drafts, moisture buildup, and infiltration of dirt and debris. Inspect window seals periodically for signs of wear or damage and replace them as needed to maintain an airtight seal. Additionally, consider applying weatherstripping or caulking around window frames to enhance insulation and prevent air leaks, further reducing the likelihood of dirt and grime entering the interior space.

By implementing these maintenance tips, you can prolong the cleanliness and clarity of outdoor windows, enhancing the appearance and functionality of your building. From adhering to a regular cleaning schedule and inspecting for damage to maintaining gutters and vegetation, proactive maintenance efforts contribute to the longevity and performance of windows, ensuring they remain a shining feature of your property for years to come.
