If you notice condensation on double-pane widows, you don't have to replace them. In some cases, you may be able to clean the moisture yourself.
Double pane windows increase window energy efficiency, but they are prone to fogging and condensation, because the seals are made from inert gas. A broken seal allows moisture to get on the window. Here are tips to clean double-pane window condensation.
Prepare to Work
For this project, you need:
- work gloves
- table cloth
- clean cloth
- hand-held vacuum cleaner
- utility knife
- white vinegar
- rubbing alcohol
Furniture and curtains that block windows decrease the air flow. Open curtains back, and rearrange furniture away from the window..
Use a hygrometer to determine the home's humidity. The ideal humidity is commonly between thirty and forty percent.
Clean the Window
Windows need proper sealing to resist moisture. Use a screwdriver to detach the frame screws, and set them aside. Some windows may be connected by mechanism that slides up and down, or by pressing it on the sides..
Carefully remove the window glass from the frame, and lay it on a flat work surface. Gently push the putty knife though the sealant next to a window pane to help you separate the panes.
Replace the knife with the hacksaw, insert it under the hole you made, and cut away the sealant. Use the putty knife to remove extra sealant. Set the window panes on a tablecloth.
Combine a tablespoon of vinegar and one cup of rubbing alcohol in one cup of water. Vacuum the glass to remove debris.
Use a clean cloth dipped in the mixture to wipe the interior of the window pane, and dry the panes with a fresh cloth. Apply a thin layer of caulk on top of the spacer and insert the glass pressing it firmly.
Add a second layer of caulk where the spacer and pane connects, then let it dry. Also check the sealant in other windows and doors nearby the double pane window.
Set up exhaust fans in rooms with high moisture like bathrooms. Turn them on, and let them run at least twenty minutes after you shower. Run stove fans for about fifteen minutes after cooking.
Remove plants from inside to outside, or in a dry room, if possible. Plants increase moisture. Add more plants that decrease moisture, such as cacti, Boston ferns, and peace lilies.
Clean moisture as soon as you notice it, and ensure the window stays sealed. If you don't trust your skill, or the window is really foggy, contact a commercial window cleaner.
