Cleaning the exterior of double-pane windows

Double-pane windows are an excellent investment for superior insulation and energy efficiency. However, condensation and dirt can get caught between the two panes, causing watermarks and an unsightly appearance. To maintain the clarity of your double-pane windows, it is important to clean both the exterior and interior surfaces. This guide will focus specifically on cleaning the exterior of double-pane windows.

Before beginning the cleaning process, it is important to gather the necessary supplies. These include a vacuum cleaner with a brush attachment, a hose or bucket of soapy water, a soft sponge or cloth for washing, clean water for rinsing, and a lint-free cloth for drying.

Start by using the vacuum cleaner with a brush attachment to remove any loose dirt, dust, or cobwebs from the window frames and sills. Pay close attention to the corners, edges, and grooves, as dirt tends to accumulate in these areas. This step will help minimise the amount of dirt you need to clean manually.

Next, use a hose or bucket of soapy water and a soft sponge or cloth to wash the exterior surface of the windows gently. Avoid using excessive force or pressure, and be careful around the edges to prevent damage to the seals. Rinse the windows thoroughly with clean water to remove any soap residue. Finally, dry the windows with a lint-free cloth, leaving them sparkling clean and streak-free.

By following these steps, you can effectively clean the exterior of your double-pane windows, improving their appearance and maintaining their insulation properties. Remember to be cautious and gentle throughout the cleaning process to avoid any potential damage to the windows or their seals.

Removing condensation from between panes

Condensation between the panes of double-glazed windows can be a common issue, especially in areas with high humidity. This happens when the seal between the two panes is damaged, allowing moisture to enter. While there are temporary fixes, the only way to truly rid a thermal window of condensation is by removing the moist air between the panes and replacing it with dry air.

Temporary fixes

  • Dehumidifier or air conditioner: Using a dehumidifier or air conditioner in a room with foggy windows can reduce moisture and humidity in the air, thereby lessening condensation on your window panes. This works best in high-humidity areas like bathrooms and kitchens.
  • Hair dryer: Applying gentle heat from a hair dryer to your window panes from the outside can help evaporate the excess moisture trapped between the two glass layers. Move the dryer in a circular motion to cover all areas of condensation.

Long-term solutions

  • Drill holes: One option is to drill a small hole (3/8-inch or so) at one top and bottom corner of the affected window. Spray various liquid solutions onto the inside faces of the panes through the top hole and suck them out through the bottom hole. Once the window is clean and dry, seal the holes with vent plugs that allow air and water vapour to escape but not enter. This process may not work for all windows, and there is a risk of breaking the glass.
  • Replace the window pane: If your window has tempered glass or laminated safety glass, your only option is to replace the glass unit. This is because it is very difficult to drill into tempered glass without breaking it.

Prevention

To prevent condensation, ensure proper ventilation in your home by opening windows or using exhaust fans in high-humidity areas. Maintain indoor humidity levels between 30% and 50%. Regularly inspect your window frames and seals for cracks, gaps, or any deterioration, and address any issues promptly. Avoid using harsh chemicals or abrasive materials when cleaning your windows, as these can damage the seal or scratch the glass.

Using a vacuum cleaner with a brush attachment

Double-pane windows are designed with an airtight seal between two panes of glass, creating an insulating barrier. This seal can become damaged over time, allowing condensation and dirt to get inside. While it is possible to clean the inside of a double-pane window, it is a high-risk process that could destroy your windows if done improperly. Before attempting to clean double-pane windows, it is important to inspect the window frames and seals for any cracks, gaps, or deterioration and address these issues to prevent further damage.

One method for cleaning double-pane windows involves using a vacuum cleaner with a brush attachment. Here is a step-by-step guide for using this method:

Step 1: Vacuum the Window Frames and Sills

Use the vacuum cleaner with a brush attachment to remove any loose dirt, dust, or cobwebs from the window frames and sills. Pay close attention to the corners, edges, and grooves where dirt tends to accumulate.

Step 2: Wash the Exterior Surface

Using a hose or bucket of soapy water, wash the exterior surface of the windows with a soft sponge or cloth. You can make your own soapy water by adding a cup of vinegar to warm water and pouring it into a spray bottle. Spray the windows and leave for about 10 minutes to allow the vinegar to remove any dirt or grime. Then, rinse thoroughly with clean water.

Step 3: Dry the Windows

After rinsing, use a lint-free or soft, dry cloth to wipe down the exterior surface of the windows. This will help prevent water stains and ensure a streak-free finish.

Step 4: Vacuum the Interior Surface

Using the vacuum cleaner with a brush attachment again, carefully vacuum the interior surface of the windows to remove any loose dust or debris. As before, pay close attention to the corners, edges, and grooves, as dirt and condensation tend to accumulate in these areas.

Step 5: Manually Clean Any Remaining Dirt

If there is any remaining dirt or condensation buildup, you may need to get creative. One option is to create a device to thread through the holes, such as attaching wool material to a drain snake. This will help you reach into the tight spaces between the panes and wipe away any remaining dirt or condensation residue.

It is important to note that this method is not suitable for all double-pane windows, especially if there is significant dirt or condensation buildup. In such cases, drilling holes or hiring a professional may be necessary. Additionally, always avoid using excessive force or pressure when cleaning double-pane windows, and be gentle when wiping around the edges to protect the seal and insulation quality.

Drilling holes to clean the interior

Double-pane windows are constructed with an airtight seal between two panes of glass, locking in air or gas to act as an insulator. When this seal is damaged, condensation and dirt may seep in. To access the interior of such windows for cleaning, you can drill holes.

Drilling holes requires some DIY skills, so if you are not confident with a drill, consider calling a professional. Drilling a few holes will allow you to tuck small desiccant packets into the window to absorb any moisture caught between the panes. The holes also allow you to rinse out the window with rubbing alcohol (isopropyl alcohol) to remove any dirt.

If there is a lot of dirt buildup, you may need to create a device to thread through the holes and use it to wipe out. For example, you can use some wool material on a drain snake. You can also use a vacuum cleaner with a brush attachment to vacuum the interior surface of the windows and remove any loose dust or debris. Pay close attention to the corners, edges, and grooves where dirt tends to accumulate.

After cleaning, it is crucial to close and secure the windows properly to ensure optimal functionality and maintain energy efficiency and soundproofing properties.
