Keeping your windows sparkling clean does more than enhance your property’s appearance—it also boosts natural light and supports the longevity of your windows. But even with the best intentions, many people fall into common traps when it comes to window cleaning. If you want streak-free, gleaming glass, it’s time to learn what you might be doing wrong.
In this blog, we’ll uncover the seven biggest window cleaning mistakes homeowners make and how to fix them. Avoiding these errors can help you get the best results, whether you're doing it yourself or hiring a professional window cleaner.
1. Cleaning Windows on a Sunny Day
It might seem like a good idea to take advantage of good weather, but cleaning your windows on a sunny day is counterproductive. The sun causes your cleaning solution to dry too quickly, leaving behind streaks and residue.
Window cleaning is best done on a cloudy day or early morning, or late afternoon when sunlight is less direct. This gives your cleaning solution time to work and makes wiping more effective.
2. Using the Wrong Cleaning Tools
Many people make the mistake of using old rags, paper towels, or even newspapers to wipe their windows. These materials not only leave lint behind but can also cause streaking or scratching.
Instead, opt for a professional-grade squeegee, a microfibre cloth, or tools used by expert window cleaner teams. Investing in the right gear is the first step towards achieving crystal-clear results.

3. Ignoring the Frames and Sills
Focusing solely on the glass and ignoring the frames and sills is a mistake many overlook. Dust, dirt, and mould often accumulate here and can run onto the freshly cleaned glass when it rains.
Before beginning the window cleaning in Bournemouth, window cleaners always start by wiping down the frames and sills. This is especially important if you're using window cleaning services, as thorough professionals will always include this in their routine.
4. Not Cleaning the Screens First
If your windows have mesh screens, not cleaning them can defeat the purpose of washing the glass. Dirty screens can transfer grime back onto your clean windows the next time it rains.
Remove the screens and wash them separately using mild soap and water. Allow them to dry completely before reattaching. A professional window cleaner will always ensure screens are spotless during an appointment.
5. Skipping Regular Cleaning Schedules
One of the most common mistakes is neglecting regular maintenance. Allowing dirt and grime to build up over time can result in stubborn stains and even damage to the glass surface.
Aim to schedule window cleaning at least once every season. You might need more frequent cleans if you live in an area with frequent rainfall or pollen. Many window cleaning services offer recurring plans for both residential and commercial properties.
6. Forgetting About Hard-to-Reach Windows
Out of sight shouldn't mean out of mind. Ignoring higher or awkwardly placed windows affects your home's overall appearance and cleanliness. These windows collect dust, spider webs, and water spots just like the ones at eye level.
Using extendable tools or hiring professional exterior cleaning services is the safest and most effective way to clean these hard-to-reach areas. Trained experts come equipped with ladders, poles, and safety gear to handle every type of window, no matter the height.

7. Neglecting Gutter and Surrounding Areas
You might wonder what gutter cleaning has to do with window cleaning, but the two go hand in hand. Clogged gutters can overflow and splash dirty water onto your windows and exterior walls.
Make sure your gutter cleaning is up to date, especially during autumn when leaves are abundant. Many companies that provide window cleaning services also offer bundled exterior cleaning services, which include gutter cleaning—a convenient and cost-effective solution for homeowners.
Final Thoughts
Avoiding these seven mistakes will make a dramatic difference in your window cleaning routine. Whether you choose to DIY or call in a professional window cleaner, staying mindful of your methods will result in cleaner, brighter windows and a more inviting home.
Remember, maintaining your windows is not just about aesthetics—it also protects your investment and enhances your living environment. For hassle-free care, consider hiring reliable window cleaning services that also provide exterior cleaning services like pressure washing and gutter cleaning.
