Do My Windows Really Need Cleaning?

Keeping your windows clean does more than just make them sparkle. On the North Shore, damp air from Lake Superior encourages algae and mildew growth. This grime not only blocks your view but can also cause etching on glass and wear down seals over time, especially with our tough winters.

What causes dirty windows around here?

The North Shore environment is tough on windows. Lake Superior's dampness promotes mildew and algae, especially on shaded sides. Dust, pollen, and even road salt spray from winter roads add layers of grime. This combination quickly obscures your view and can begin to damage surfaces if left too long.

Can dirty windows harm my home?

Yes, grime, especially from algae and mildew, holds moisture against window frames. This moisture can lead to wood rot or seal failure, common problems around Two Harbors and Silver Bay. Over time, mineral deposits from hard water or sap can etch the glass itself, making it permanently cloudy.

How often should I clean my windows?

For most homes along the North Shore, twice a year is a good starting point. Spring cleaning gets rid of winter's buildup, while a fall cleaning prepares them for the next cold season. Seasonal cabins might need attention before opening and after closing to remove debris collected over months.

Is there a trick to cleaning windows yourself?

For a streak-free shine, use a squeegee with a professional-grade window cleaning solution. Avoid cleaning in direct sunlight, as the solution can dry too fast and leave streaks. Always use a clean cloth or scrubber to apply the solution and change your squeegee blade often for the best results.

Common questions

Will cleaning my windows prevent damage?

Regular cleaning helps prevent long-term damage. Removing corrosive bird droppings, mineral deposits, and mold growth stops them from etching the glass or degrading frames. It extends the life of your windows, saving you from more costly repairs down the road.

What's the best way to clean windows without streaks?

For a streak-free finish, use a quality squeegee and a professional-grade cleaning solution. Work in shaded areas to prevent rapid drying. Always start with clean tools and replace squeegee blade regularly. These steps help achieve sparkling, clear windows.

Can cleaning my windows improve my home's energy efficiency?

While cleaning itself doesn't directly change energy efficiency, it does help. Clean glass allows more natural light and warmth into your home, reducing the need for artificial lighting and heating on sunny days. It also lets you spot seal issues that might leak energy.
