10 Common Window Cleaning Mistakes to Avoid (Salt Lake City Homeowners Guide)
If your windows still look streaky or dull after cleaning, you’re not alone. Many homeowners and businesses in the Salt Lake Valley unknowingly make simple mistakes that lead to poor results—or even permanent damage.
At Ontos Window Cleaning, we’ve seen it all. Whether you’re maintaining a luxury home in Draper or managing a storefront in Salt Lake City, avoiding these common window cleaning mistakes can save you time, money, and frustration.
Here are the 10 most common window cleaning mistakes to avoid—and what to do instead.
1. Cleaning Windows in Direct Sunlight
Salt Lake City gets plenty of sunshine—but cleaning your windows under direct sunlight is a mistake.
Why it’s a problem:
The heat causes water and cleaning solutions to dry too quickly, leaving streaks and residue behind.
What to do instead:
Clean windows early in the morning or later in the evening when surfaces are cooler.
2. Using the Wrong Cleaning Solution
Many people rely on standard household cleaners that aren’t designed for glass.
Why it’s a problem:
Harsh chemicals can leave residue, damage window coatings, and attract more dirt over time.
Better option:
Use a professional-grade glass cleaner or purified water for a streak-free finish.
3. Using Paper Towels or Old Rags
It may seem convenient, but paper towels and old cloths are one of the biggest culprits of streaky windows.
Why it’s a problem:
They leave lint, streaks, and uneven cleaning patterns.
Better option:
Use a microfiber cloth or a professional squeegee for best results.
4. Skipping the Window Frames and Screens
Most people focus only on the glass and ignore everything around it.
Why it’s a problem:
Dirty frames and screens can transfer dust and grime back onto freshly cleaned windows.
What to do instead:
Always clean screens, tracks, and frames before washing the glass.
5. Not Removing Hard Water Stains Properly
In areas around Salt Lake City, hard water stains are common due to mineral buildup.
Why it’s a problem:
Scrubbing aggressively can scratch the glass and make the problem worse.
Better option:
Use specialized stain removal products or professional services to safely restore clarity.
6. Using Too Much Cleaning Solution
More soap doesn’t mean cleaner windows.
Why it’s a problem:
Excess solution leaves behind residue and streaks.
What to do instead:
Use a small amount of cleaner and rinse thoroughly for a spotless finish.
7. Cleaning Without the Right Tools
Trying to clean windows without proper tools leads to inconsistent results.
Why it’s a problem:
You may miss spots, leave streaks, or spend far more time than necessary.
Professional tools include:
Squeegees
Extension poles
Water-fed pole systems
Purified water systems
8. Ignoring Safety on Multi-Story Homes
Many homes in Draper, Murray, and surrounding areas have multiple stories or hard-to-reach windows.
Why it’s a problem:
Climbing ladders without proper training or equipment can be dangerous.
What to do instead:
For second-story or high windows, consider hiring a professional window cleaning company.
9. Neglecting Regular Cleaning
Waiting too long between cleanings makes the job harder and less effective.
Why it’s a problem:
Dirt, pollen, and mineral buildup become more difficult to remove over time.
Best practice:
Schedule regular cleanings to maintain clear, bright windows year-round.
10. Forgetting About Solar Panels
If your home or business has solar panels, they need cleaning too.
Why it’s a problem:
Dust and debris can reduce energy efficiency significantly.
Solution:
Professional solar panel cleaning helps maintain optimal performance and long-term savings.
