Common Questions About How to Clean Double-Pane Windows

What are double pane windows?

A double-pane window has two pieces of glass and space in the middle, which is an airtight seal. This seal also acts as an insulator, keeps the house warm in winter and cool in summer, and saves energy bills. This is because it does not allow any of the air to escape the home or come in.

Double-pane windows have two panes of glass, many with insulating argon gas between the panes. The additional layer of material, plus the insulating gap in between, is what makes them stand out. Two or three panes of glass mean more layers of protection between the weather and your home.

What causes double pane windows to get dirty?

The outside layer of the window can get dirty from sweet children’s handprints or mouth prints or by simply touching the window. However, if the inside of the window is dirty, this means the seal is broken, and you can clean it, but the window may need replacing.

Can you clean inside double-pane windows?

Double-pane windows utilize two pieces of glass that are constructed with an airtight seal between them. Unfortunately, this means it’s not possible to clean between the two glass panes without ruining the window.
If the seal is broken and dirt/moisture starts to show, it is best to replace the window.

How do you know the seals are broken on a double pane window?

Common signs include:

  • Condensation between the two panes of glass because moisture can now get in
  • Rust will start to build-up
  • Foggy and milky look on the panes of glass
  • Dirt and grime appear

How do you remove the haze from a double-pane window?

  1. Drill a set of small holes at the top of the window and one small hole in the bottom window corner. You could also opt to drill one or two small holes ¼ inch into the window seal and 2 inches from the corner.
  2. After drilling, pour isopropyl alcohol into the holes.
  3. You could also insert a desiccate package or pellets in the space. This will help remove any fog or condensation.
  4. Another idea is to put a sock on the end of a wire and duct tape the sock on. You will use this as a duster. Please put it in the hole you made and try to clean the window. The hole must be big enough, though, to do this, and that is where this is tricky.

  • Don’t push your furniture right up against your walls

Additional Tips on How to Clean Double Pane Windows

  • If you do drill holes, do not reseal them when you are done. Leaving them open will allow you to clean the window again and not lock in the moisture.
  • When doing spring cleaning, it is a good idea to check out all of the windows. If you have a window ac unit in your windows, this is an excellent time to either leave it in the window to clean or take it out of the window, replace the filter, clean the coils, and fins, and wash the pans.
  • Check the window sash of the window by making sure it slides up and down easily and can lock for safety.
  • If you drill holes to clean the inside of a double pane window, keep in mind that drilling holes in the windows could damage the glass and ruin the window’s efficiency, so it should be done as a last resort.
  • Pointing a fan on the holes is another idea and may help dry out the inside of the window. It will get the air flowing and allow the water to evaporate but it won’t work for dirt.
