These types of windows can help keep heat and cool air because of the insulation, but they may also become foggy. This is especially true for older windows and doors. The fogging is a result of a broken or failed seal, which allows moisture into the space between the two panes of glass.
If the seal has been damaged due to extreme cold or hot temperatures, there’s not much you can do. You cannot repair it and your windows will need to be replaced, if you want new seals. However, if you cannot replace your windows, you can still get rid of the fog.
Cleaning Foggy Double-Pane Windows and Doors
Once you find out what is involved in cleaning a double-pane window or door with a broken seal, you may just want to hire a professional. You will have to remove the seal, clean both panes of glass, put the window back together and re-seal it just as they would at the factory. If you don’t, the fog will come back as soon as moisture seeps in.
You can insert silica desiccant between the panes of glass to help soak up the moisture. However, this is only a temporary fix.
Hire a Professional Window Cleaner
If you have foggy double-pane windows and doors you need cleaned, hire a professional. They will be able to clean the fogginess and provide a solution for the time being. They will also be able to tell you if you should hire a professional to replace the windows or if you can still use the windows with regular cleaning.
Even though cleaning foggy double-pane windows may seem like a DIY project, it’s far better to hire a professional. You may waste an entire weekend cleaning the windows just to have them fog up again by the next weekend. A professional can provide a better solution that will at least last until the next scheduled cleaning.
