Many homeowners—especially families caring for aging parents—gently ask this. And yet, intense heat does more than dry your cleaning solution too fast.
In fact, once temperatures rise above 25 °C (77 °F), cleaners evaporate quickly.
That leaves streaks. Worse still, sudden temperature shifts can cause thermal stress and even crack glass in our Canadian homes.
So, what can you do?
A chore that’s meant to simplify life becomes frustrating. Ladders feel unsteady. The sun glares. And streaky windows dim bright moments with family. That’s where our professional insight makes the difference.
Here’s something few folks know: using distilled water plus a high-quality squeegee cuts smudges nearly in half—even in hot spells—thanks to reduced mineral residue and slower evaporation.
At Custodia, we recommend timing your window cleaning for early morning, late afternoon, or overcast days. And we offer expert window cleaning services—complete inspections, protective film installation, and streak-free results.
If you want clear, safe, and beautiful windows for your home (and loved ones), read on to discover how.
How Does Temperature Affect Window Cleaning?
As we mentioned earlier, cleaning windows in hot weather can lead to frustrating streaks and safety risks. Now, let’s dig deeper. When the temperature climbs above 25 °C (77 °F), window cleaners face a common enemy—thermal shock.
This happens when hot glass suddenly meets cold cleaning solution. The drastic temperature change causes stress inside the glass, which can lead to cracks or even breakage.
This risk is real for many Ontario homes during heatwaves or sunny afternoons.
Beyond damage, fast evaporation of cleaners in heat causes streaks that ruin your view and waste your effort.
Imagine trying to enjoy family moments inside a bright, sunlit room—only to be distracted by smudged windows. It’s frustrating and stressful, especially for homeowners caring for aging family members.
To protect your windows and peace of mind:
- Clean during cooler times—early morning or evening
- Use gentle products like distilled water for a streak-free finish
- Avoid direct sunlight when cleaning
At Custodia, we understand these challenges. That’s why our window cleaning services focus on timing, technique, and care—keeping your home clear, safe, and inviting.

Best Practices for Hot Weather Window Cleaning
in 5 Easy Steps
You already know the risks of cleaning windows in hot weather.
But here’s the good news—you can achieve a streak-free shine, even when Ontario temperatures soar. And when your windows sparkle, your living spaces feel lighter and more inviting—a perfect setting for family moments and quiet relaxation.
Follow these simple yet expert-backed steps:
Pre-wet the glass
Always start by pre-wetting the entire glass with cool water. This step cools the surface and minimizes thermal shock when applying the cleaning solution. It also helps slow evaporation so you have time to work effectively.
Work in the shade
Choose shaded windows or wait until early morning or late evening to clean. Direct sun heats the glass and causes streaking. By working in shade, you extend your cleaning window and ensure better results.
Use distilled water
Hard water often leaves unsightly spots that ruin your effort. Use distilled water to prevent mineral deposits and enjoy that crystal-clear view.
Keep the surface wet
Don’t rush. Keep glass damp throughout the process by misting as needed. This prevents the solution from drying too fast and avoids streaks.
Perfect your squeegee technique
Use a high-quality squeegee. Start from the top and pull down in smooth, slightly overlapping strokes. Wipe the blade between each pass to avoid dragging debris across your glass.
And remember—if time or weather aren’t on your side, our professional handymen and window cleaning experts across Ontario can help.
We’ll do the hard work so you can enjoy a brighter, cleaner home—stress-free.
