There’s something deeply satisfying about crystal-clear windows. They brighten your home, let in more natural light, and elevate the entire feel of your space. But achieving truly streak-free glass is harder than it looks—and most homeowners have found this out the frustrating way.
At Vitres Royal, we’ve cleaned thousands of windows across Montreal and developed techniques that consistently leave a flawless, streak-free finish. In this blog, we’re sharing what really goes into professional-quality results, why DIY methods often fall short, and how our process delivers clarity you can see and feel.
Common Myths About Window Cleaning
Before we dive into pro tips, let’s bust a few common myths that tend to lead homeowners down the wrong path:
Myth #1: Newspaper is the best tool for cleaning windows
While it was once a go-to method, today’s newspaper ink and paper quality often leave more residue than results. Plus, it can easily smear moisture around instead of removing it.
Myth #2: Vinegar and water is all you need
While this mix can help cut basic grime, it’s not strong enough for oily films, mineral spots, or environmental pollutants—especially on exterior windows exposed to the elements.
Myth #3: Cleaning on a sunny day gets better results
In fact, sunlight causes the cleaning solution to dry too quickly, leading to streaks and residue. Overcast days are ideal for streak-free results.
What the Pros Do Differently
The key to professional results isn’t just the tools—it’s the method. Here’s how our team at Vitres Royal consistently delivers sparkling, streak-free windows.
1. We Use Purified Water Systems
One of the biggest culprits behind streaks is minerals in tap water. When left to dry on glass, those minerals leave behind spots and streaks. That’s why we use purified or deionized water, which contains no impurities. It dries clean—no need for extra wiping or buffing.
2. We Squeegee Like Pros
The squeegee is a pro’s best friend, but using it correctly takes practice. We use commercial-grade squeegees with replaceable rubber blades, working in fluid, overlapping strokes from top to bottom. Done right, this removes every drop of water and leaves a clean, dry surface.
Cheap squeegees or inconsistent pressure often result in missed spots or, ironically, more streaks.
3. We Tackle the Edges and Frames
Even if the glass is spotless, dirty edges or drips from the frame can instantly ruin the finish. That’s why we always wipe down the sills, edges, and frames during every job. It’s a small step that makes a big difference in the overall result.
4. We Use the Right Tools for the Right Window
Not all windows are the same—older wood-framed panes, French windows, or large modern glass surfaces all require different approaches. We tailor our tools and cleaning products to match each window’s material, shape, and size.
5. We Clean Inside and Out
You might be surprised how many streaks come from the inside of the glass, especially if you cook near windows or have pets and kids touching the glass. We always clean both sides thoroughly, ensuring nothing gets overlooked.
Why DIY Efforts Fall Short
DIY cleaning often skips steps, uses poor-quality products, or misses important details like window corners and sills. Even if you get decent results, they usually don’t last.
Professional cleanings from Vitres Royal:
- Last longer due to better techniques and products
- Remove deep-seated grime and residue

Plus, we leave no mess behind—just spotless, gleaming windows.
