How to Remove Haze and Condensation from Double Pane Windows

Double pane windows are made up of two separate pieces or panes of glass sealed together with a pocket of air in between. This air pocket acts as an insulator, slowing down heat transfer and improving the window’s energy efficiency. However, when the seal between the panes fails, moisture can seep in, causing the windows to become foggy or hazy.

Causes of Fogginess in Double Pane Windows

There are several reasons why double pane windows may become foggy or hazy:
Broken seal: Over time, the seal between the window panes can break down, allowing moisture to enter and condensation to form.
Humid climate: In areas with high humidity, moisture in the air can more easily penetrate the seal and cause fogginess.
Damaged frame: If the window frame is damaged or rotting, it can allow moisture to enter and cause the seal to fail.
Age: Older double pane windows are more prone to seal failure and fogginess.

Challenges of Cleaning Double Pane Windows

Cleaning double pane windows can be challenging due to the sealed nature of the window unit. Some of the main challenges include:
Removing the seal: To clean between the panes, the seal must be broken, which can be difficult to do without damaging the glass.
Reassembling the window: After cleaning, the window must be reassembled and resealed, which requires precise techniques to ensure a proper seal.
Potential for damage: Attempting to clean between the panes can easily lead to cracks or breaks in the glass if not done carefully.

Professional Approach to Removing Haze

If you’re not comfortable attempting to clean your double pane windows yourself, it’s best to hire a professional window cleaning service. Professional cleaners have the tools and expertise to safely remove haze and condensation without damaging the window. They can also provide recommendations for window replacement if the seal is beyond repair.

DIY Methods for Removing Haze

If you’re willing to take on the challenge of cleaning your double pane windows yourself, there are a few methods you can try:
Dehumidifier: Place a dehumidifier next to the foggy window and let it run for several hours to remove moisture from the air and reduce condensation between the panes.
Drill a small hole: Carefully drill a small hole near the bottom of the window frame to allow moisture to escape. Use a cleaning solution or a dehumidifier to remove any existing moisture.
Use a wire or cloth: Attach a thin wire or a drain snake wrapped in a soft cloth to a hanger. Carefully insert the wire or cloth between the panes and wipe the interior surface of the glass to remove haze and condensation.
Apply rubbing alcohol: Use a turkey baster to drip a few drops of rubbing alcohol between the panes. The alcohol will help clean the glass and remove moisture.
It’s important to note that attempting to clean double pane windows yourself carries risks, such as damaging the glass or failing to properly reseal the window after cleaning. If you’re not confident in your ability to clean the window safely, it’s best to hire a professional.

Preventing Future Fogginess

To prevent future fogginess in your double pane windows, there are a few steps you can take:
Repair any cracks or breaks: Even small cracks or breaks in the glass can allow moisture to enter and cause fogginess.
Maintain the window frame: Keep the window frame in good condition by regularly inspecting for signs of damage or rot.
Consider window replacement: If your double pane windows are older or the seal is beyond repair, it may be worth considering window replacement for long-term prevention of fogginess.
