The task of window cleaning isn’t easy, but it’s essential. You want sparkly windows, but you’re worried about scratches?
After all, scratched glass can ruin a window’s appearance and even decrease its energy efficiency. Anyhow, it’s not that big a deal.
As long as you take care during cleaning, it’s easy to keep them looking great without any risk of damage.
You may damage your windows if you rely on harsh materials such as steel wool or abrasive cleaners like baking soda. These materials are designed to scrub away tough deposits but can easily scratch the glass if misused.
Too much pressure while scrubbing can also cause scratches in the glass or frames. Even misusing a squeegee can damage windows over time.
The best way to avoid scuffs and scratches when window cleaning is to use soft materials and gentle strokes. To reduce the risk of scratches, it’s best to use specialized products designed to clean windows without causing any damage.
For instance, use a clean cloth or microfiber towel with glass cleaner or water to wipe away dirt and debris. And if it turns out that your windows have been scratched, don’t worry; there are plenty of ways to fix them.
Fortunately, most of the minor scratches can be fixed fairly easily at home with products like glass scratch repair kits or special polishing compounds. Let’s discuss this common concern and provide you with all the information you need to keep your windows clean.
Types of Window Scratches
Before diving into how to prevent scratches when cleaning your windows, let’s look at the types of scratches on glass windows.
Minor scratches on glass windows typically appear as light streaks or lines on the surface of the glass. These imperfections are usually caused by dust particles, dirt, or other foreign objects that come into contact with the window pane while cleaning.
A glass polishing compound or scratch repair kit can easily fix minor scratches.
Deep scratches, on the other hand, are more serious as they penetrate deeper through the glass surface. These types of scratches usually occur when a metal or hard plastic object comes into contacts with the window pane, such as a scraper or blade.
Unfortunately, DIY methods cannot repair these imperfections and may require a professional glass replacement.
Crack lines are also considered deep scratches because they penetrate through the entire glass window pane and require a full replacement. They are the most serious type of damage and usually indicate that the window has been heavily impacted.
Crack lines (also called thermal stress cracks) are typically caused by sudden temperature changes, improper installation, strong winds, or pressure from an object hitting the window.
How Does Window Glass Get Scratched?
We’ve discussed the types of scratches; now, let’s talk about the causes. Here are some common factors that can lead to scratches on glass windows:
Hard Water Minerals
Hard water contains high levels of dissolved minerals such as calcium, magnesium, and silica. When hard water evaporates from the glass surface, it leaves behind mineral deposits that can accumulate over time and form a hard crust on the windowpane.
This crust is unsightly and abrasive and can scratch the glass surface if not removed properly.
Debris and Dust Particles
Debris and dust particles are major culprits that can cause scratches on your windows. When you clean your windows, removing all loose debris and dirt particles is important before applying any cleaning solution or tool. These particles can act as abrasives and scratch the glass surface if not removed.
Sometimes loose debris was likely baked onto the glass during tempering if it wasn’t completely removed during the washing phase. This small debris creates microscopic bumps on the surface of the glass, which detach during normal window cleaning, resulting in major scratching across the entire pane.
Damage Caused by Subcontractors during the Construction
More often than not, scratches on glass after a window cleaning service are due to faulty tempered glass or damage inflicted by subcontractors during the construction process. Ladders and other heavy equipment can easily cause scratch marks, gouges, and scuffs to glass surfaces.
Mortar and other materials that are smeared on glass or windows can leave a thick residue that is difficult to remove. Dry-razor blading is an abrasive technique used to strip away paint from surfaces, but it often leaves behind scratches in the glass underneath as well.
Common Window Cleaning Mistakes that May Result in Scratches
Using Harsh Cleaning Solutions
Another important factor to consider is the type of cleaning solution you use. Some cleaners contain harsh chemicals that can eat away at the protective coating on your windows, making them more susceptible to scratches.
For example, using window cleaners with abrasive ingredients such as ammonia or bleach can easily strip away the protective coating and cause scratches. Therefore, opting for a mild detergent such as dish soap to clean your windows is best.
Use of Abrasive Tools and Materials
Cleaning windows with abrasive tools and materials can be disastrous. Abrasive tools are those that have the potential to scratch or damage the glass surface of your windows. Some common abrasive materials include steel wool, scouring pads, and even paper towels.
While these materials may seem harmless, they can cause serious damage to your windows over time. Scratches on your windows can be unsightly and weaken the glass, making it more prone to breakage.
Sandpaper or razor blades can remove paint, dirt, and residue from glass surfaces. While this may seem like a quick and easy solution for cleaning your windows, it can have disastrous consequences.
Abrasive tools such as these are highly likely to cause scratches on the glass surface of your window pane. And once the scratch is there, there’s no way to reverse it.
Using Dirty Rags or Sponges
Using dirty rags or sponges to clean your windows may seem like a quick and easy solution, but it can actually cause significant damage to your windows. When you use a dirty rag or sponge, you risk rubbing dirt and debris into the glass surface, which can lead to scratches.
In addition to the risk of scratches, dirty cleaning tools can leave streaks on your windows. This is because the dirt and debris on the rag or sponge can transfer onto the glass surface as you clean it, leaving behind unsightly marks.
Cleaning in Circular Motions
Using circular motions to clean windows is a common mistake. While it may seem like an effective way to remove dirt and grime, it can actually cause scratches on the glass surface.
Circular motions create friction between the cleaning tool and the glass, which can lead to small scratches over time. These scratches may not be immediately noticeable, but they can accumulate over time and eventually become visible.
Applying Too Much Pressure on the Glass Surface
Glass is a delicate material that can easily be damaged if not handled with care.
Using excessive force while cleaning your windows can cause scratches and even cracks on the glass surface. This is especially true for tempered glass, which is commonly used in modern buildings and homes. Tempered glass is designed to break into small pieces rather than shatter into sharp shards, but it is still susceptible to scratching.
Ways to Prevent Scratching Your Windows While Cleaning Them
Preventing scratches is the most important thing about cleaning windows. Scratches can be unsightly and compromise the integrity of the glass surface. Fortunately, there are several ways to prevent scratching your windows while cleaning them.
Choosing the Right Cleaning Tools and Materials
Choosing the right tools and materials can make all the difference in preventing scratches. Here are some tips for selecting the best options:
Use a soft cloth or microfiber towel
Avoid using rough materials like paper towels or old rags that may contain debris that can scratch the glass surface. Instead, opt for a soft cloth or microfiber towel with no lint or residue.
Always use clean rags or sponges. If you’re using a cloth, ensure it’s free of any dirt or debris before cleaning. If you’re using a sponge, rinse it thoroughly with clean water before use.
Different types of rags and sponges are better suited for different cleaning tasks. For example, microfiber cloths are great for cleaning glass surfaces because they are gentle and won’t scratch the glass.
On the other hand, abrasive sponges should be avoided at all costs as they can easily scratch delicate surfaces.
Choose a non-abrasive cleaner
Many cleaners contain harsh chemicals and abrasive materials that can damage your windows over time. Look for a non-abrasive cleaner specifically designed for glass surfaces.
Avoid using glass cleaners with ammonia or vinegar, as these can be too harsh for window cleaning. Instead, opt for a mild detergent that won’t damage the surface of your windows.
Use a squeegee
A squeegee is an effective tool for cleaning windows without leaving streaks or scratches. Choose one with a soft rubber blade to avoid causing damage.
When using a squeegee, use gentle pressure and make sure to pull the blade in only one direction to prevent scratching.
Avoid using razors or scrapers
While these tools may seem like a quick fix for stubborn stains or grime, they can easily scratch your windows if used incorrectly. Try to stick to more gentle cleaning methods like soft cloths and squeegees.
Properly Prepping and Adopting Recommended Window Cleaning Techniques
To properly prep the glass surface before cleaning, you need to ensure no debris or dust particles on the window. Any dirt, dust, or debris can cause scratches on the glass surface while cleaning.
- Start by using a soft-bristled brush or a microfiber cloth to remove any loose dirt and debris from the window frame and sills.
- Then, use a vacuum cleaner with a soft brush attachment to remove any remaining dirt.
- Use a gentle cleaning solution that is specifically designed for windows.
- Avoid using harsh chemicals as they can damage the glass surface. Instead, opt for a mild soap solution or a vinegar-based solution. Mix the solution in a bucket of warm water.
- Dip a soft microfiber cloth into the cleaning solution and wring out excess water. Start cleaning the window from top to bottom in straight lines or vertical strokes.
- Clean windows in straight lines or up-and-down motions. This reduces the friction created during cleaning and minimizes the risk of scratches. Avoid circular motions as they can leave streaks on the glass surface.
- Use a light touch when applying pressure. Avoid pressing too hard on the glass surface or using abrasive materials that could damage the surface.
- Once you have cleaned one side of the window, rinse it thoroughly with clean water to remove any soap residue. Use a squeegee to remove excess water from the glass surface starting at the top and working your way down in straight lines.
- Use a lint-free cloth or chamois leather to dry off any remaining moisture from the glass surface. Ensure you dry off all areas of the window thoroughly to prevent water spots.
- Finally, wax your windows to protect them from dirt, dust, and other debris. This will also make it easier for you to clean the windows in the future.
Take Extra Precaution During the Construction Period
Contractors should take extra precautions when handling windows and other fragile components. Ladders and any other equipment near the windows should always be protected by protective barriers, and all materials should be carefully applied.
Proper safety measures will help ensure that any damage caused by subcontractors does not lead to long-term cosmetic problems in the building’s facade. For instance, if scaffolding is used near windows, the subcontractor should ensure that any debris or equipment is not leaning against the window frame.
Furthermore, all construction materials should be properly secured and transported away from the window area to avoid accidental damage during the cleaning and repair processes.
Finally, all tools used for window cleaning and repair should be inspected to ensure they are free from dirt, dust, and debris before being used.
Taking the necessary safety measures during construction periods can help prevent any issues with your windows in the long run.
Follow the Manufacturer’s Recommendations
Always follow the manufacturer’s recommendations for cleaning and maintenance of your windows. Specialized cleaning solutions or tools may sometimes be required to care for the windows properly.
Some manufacturers may even recommend a professional window cleaning service instead of attempting to clean the windows yourself. If this is recommended, ensure that you only hire a reputable, experienced window cleaner knowledgeable about proper window cleaning techniques.
