Foggy windows do more than dull your view. In commercial spaces, they cast a shadow on professionalism. At home, they dampen natural light and even signal deeper moisture problems. If you’ve tried the usual tricks and nothing works, this is the guide for you.
At Insight Service Solutions, we’ve restored clarity to thousands of windows across Winnipeg—from low-rise storefronts to high-rise towers. And now, we’re giving you five fixes that actually work. Let’s demystify the fog!
Before jumping to cleaning solutions, it’s crucial to understand why your windows are foggy.
Insight Fix: Try a basic fog test. Wipe both sides of the window. If the fog doesn’t disappear—it’s trapped. That’s when our High-Rise Window Cleaning or Facade Cleaning Services come into play.
Forget harsh chemicals. One of the best ways to clean foggy windows naturally is this tried-and-true solution:
Mix:
Spray it generously and use a microfiber cloth to wipe in circular motions. Vinegar cuts through mineral buildup and soap scum—common culprits behind hazy windows.
Pro Tip: Avoid paper towels. They leave lint and micro-scratches. Stick to a clean microfiber or squeegee.
For tougher buildup, sprinkle a little baking soda on the cloth before wiping. It adds gentle abrasion to remove stuck-on grime without damaging the glass.
Bonus Tip: If you're cleaning multiple large windows or storefront glass, section your work to avoid streaks—clean one area at a time and immediately dry it with a squeegee.

If your windows keep fogging up, you’re not just dealing with dirt. You’re battling excess humidity.
Additional Fixes:
Did You Know? Buildings with poorly maintained HVAC systems often experience ongoing window fog and condensation issues, especially in transitional seasons like spring and fall.
Bonus: Reduced humidity means lower energy bills and fewer foggy mornings.
A foggy window might be telling you more than “clean me.” If fog returns no matter how often you wipe, check:
This kind of damage allows moisture to sneak in—creating permanent fog. The fix? Either re-seal or replace the glass. In high-traffic commercial spaces, this isn’t optional.
Expert Tip: Thermal imaging tools can help identify hidden leaks around frames. If your building manager hasn’t done a window audit in the last 2 years, now’s the time.
Here’s the truth: even the clearest window won’t stay clean without a plan.
Why it Matters:
Case in Point: One Winnipeg property manager saw a 17% drop in heating costs after regular window and gutter maintenance improved insulation performance.
If your windows are decades old, it may be time to upgrade. Newer double- and triple-pane windows are better insulated, more energy efficient, and less likely to fog.
What to look for:
Pro Insight: Even with upgraded windows, maintenance is key. Don’t let a premium product lose its edge to buildup or neglected frames.
If you’re managing a commercial property, this is one of the smartest upgrades you can make for long-term clarity and energy savings.
How do I know if the fog is inside or outside the glass?
Wipe both sides. If it stays foggy, the issue is between the panes and likely due to a broken seal.
Will replacing the window fix the fog?
Yes—if the fog is between the panes. A full replacement or sealed-unit replacement may be necessary.
Can I prevent future fogging?
Yes! Maintain proper indoor humidity, clean regularly, and ensure proper insulation around your windows.
Do I need a professional for this?
If your windows are hard to reach, part of a commercial building, or foggy between panes—yes. Professionals like Insight Service Solutions have the tools and training to restore clarity safely and effectively.
Can foggy windows lead to health problems?
Yes—persistent condensation encourages mold growth, which can trigger allergies and respiratory issues.
What’s the fastest way to clear fog in a pinch?
Use a hair dryer or defogging spray on the inside pane to quickly evaporate surface moisture. This is a temporary fix, not a permanent solution.
