Cleaning commercial glass windows can be challenging, especially when dealing with stubborn stains and streaks. These windows are larger and more exposed to the elements than residential windows, making them prone to accumulate dirt, grime, and spots. 

This article provides a comprehensive guide on how to clean commercial glass windows effectively. We’ll cover everything from the basic tools required to step-by-step methods for achieving that streak-free shine.

So, if you’re looking for efficient ways to tackle this task, keep reading to learn the best practices in commercial window cleaning near me.

Keeping Your Glass Windows Clean Has Its Advantage

Maintaining clean glass windows is not just about aesthetics, it also plays a significant role in the functionality of a building. 

Businesses often invest in window cleaning services because dirty windows detract from the building’s appearance, giving off an unprofessional and neglected impression to clients and potential customers.

Beyond appearance, clean windows offer practical benefits, especially during colder months. They allow maximum natural light to penetrate the interior, which can help warm the building naturally. This reduces reliance on artificial heating, leading to energy savings. 

Additionally, ample natural light is known to mitigate the effects of Seasonal Affective Disorder (SAD), a type of depression related to changes in seasons. Well-lit environments can improve mood and overall well-being.

6 Steps to Cleaning Commercial Glass Windows

Achieving streak-free windows in a commercial setting can be straightforward with the right approach and tools. Many businesses need help removing tough stains and debris.

With the right resources, you can ensure your windows remain clean and clear, enhancing the overall look of your business.

1. Start Your Window Cleaning from Top to Bottom

To clean your commercial windows, it’s essential to begin the cleaning process at the top of the window and work downwards. This method takes advantage of gravity, allowing any excess cleaning solution to drip into areas you still need to address.

By starting at the top of the window, you ensure drips don’t spoil clean, already-washed sections at the bottom. This approach helps effectively tackle stains and dirt and prevent the reapplication of dirt and cleaning solution on the glass surfaces you have already perfected.

Remember, the goal is to leave every inch of the window spotless and streak-free, which requires a systematic and top-down cleaning strategy.

2. Use the Proper Tools: Spray Bottle, Water-fed Pole System &, Squeegee

To achieve clean windows, moisten them with a spray bottle or a water-fed pole system, which is especially effective for higher areas. Once wet, use a squeegee, applying long, overlapping strokes. Focus on the edges and corners, where dirt often accumulates.

After each squeegee stroke, wipe the blade with a natural sponge. This process helps prevent watermarks and ensures a thorough, uniform clean across the entire window surface.

3. Prepare Your Window Cleaning Solution

The key to tackling dirty windows lies in the right cleaning solution. You can make a simple yet effective mixture using warm water and white vinegar, which is known for its natural cleaning properties.

Alternatively, a dish soap and water blend works well, especially for removing tough grime. However, be mindful that some soaps can leave residue behind.

Various window cleaning products are available for a more specialized approach, designed to provide a thorough and gentle cleaning. These solutions work wonders on glass surfaces and can be safely used on window frames and sills, ensuring your entire window, including the window screens, is sparkling clean and streak-free.

4. Clean Both Sides of the Window

Cleaning windows’ interior and exterior is crucial for achieving completely spotless commercial windows. For the exterior, simplify the process by attaching a high-pressure spray nozzle and a solution-dispensing cylinder to your garden hose.

Add a bit of liquid dish soap to the container, and choose from various spray patterns for an efficient clean. This method quickly removes grime and dirt, providing a professional-level wash.

For interior windows, the ideal approach involves using a scrubber and squeegee. This combination ensures a thorough and effective cleaning, easily tackling fingerprints, smudges, and indoor pollutants.

Remember, interior and exterior window cleaning techniques differ, but both are essential for streak-free windows.

5. Remember to Clean Window Corners & Rubber Gaskets

An often overlooked but crucial part of window cleaning is checking the corners and rubber gaskets on your windows. It’s essential to choose these areas thoroughly. If not properly removed, water trapped under the rubber gaskets can cause unsightly marks.

Carefully dry window edges and corners to prevent water from seeping out and leaving residues on the glass panes later. 

6. Apply Proper Window Cleaning Techniques

Effective window cleaning depends on using the right technique. We recommend applying the cleaning solution to a microfiber cloth, or soft rag rather than directly applying it to the glass. 

You need extra caution for windows with wooden frames, as prolonged exposure to cleaning products can cause warping and damage to the wood. 

Additionally, spraying directly onto the glass often leads to overuse of the cleaning product, which can result in excessive suds and potentially leave residue.

By applying a minimal amount of cleaner to your cleaning tool, you can achieve a clear and polished finish on your windows without the risk of leaving any residue behind.

How Often Should Glass Windows Be Cleaned?

Determining the right frequency for cleaning commercial glass windows depends on various factors, including climate, location, and personal preferences. Generally, it’s recommended to clean windows inside and out at least twice a year.

However, weather conditions, environmental debris, and geographical location can necessitate more frequent cleaning. For instance, windows in urban areas may gather dirt more quickly due to pollution and passing traffic.

Similarly, coastal buildings might require more regular cleaning due to salty air. Each business will have unique needs based on these variables, so adapting your window cleaning schedule accordingly is essential.

Comparing DIY Techniques vs Professional Window Cleaning Services

While DIY window cleaning might seem cost-effective, it often requires specialized tools and solutions that are used by professionals.

For instance, professionals use high-grade squeegees, eco-friendly cleaning solutions, and water-fed pole systems, which are not typically available for DIY.

Professional services also bring expertise in tackling challenging areas, such as high or hard-to-reach windows. The cost of professional window cleaning usually depends on the number of windows, their sizes, and building height.

While DIY can handle basic cleaning, professional services ensure thorough, safe, and efficient cleaning, especially for larger or more complex buildings.

Consider hiring expert cleaning services for safety and efficiency, especially for multi-story buildings.
