      Double-hung windows are one of the most common window styles found in homes. They look stylish, add character to the space, and ensure better ventilation. However, just like other items in the home, they also collect dirt, dust, and grime over time.

      Knowing how to clean these windows is important for easy maintenance. Cleaning double-hung windows is easy and can be done without any complicated tools. This article explains how often windows should be cleaned and a few effective ways to clean these unique windows.

      What is a Double-Hung Window?

      A double-hung window has two sashes, both of which slide up and down within the frame. This feature makes double-hung windows more versatile and easier to use, so that both sashes move, not just the bottom one.

      This gives more control over how much air comes in and where it comes from. It is a classic design that has been around for a long time and is known for its functionality. As a popular choice among homeowners, it offers both aesthetics and practicality.

      How often one cleans their double-hung windows depends on where you live, the surrounding environment, and individual preferences. A general rule of thumb is to clean them at least twice a year, with spring and fall being the most practical times.

      Cleaning during these seasons helps prepare the window for changes in the weather. This also removes all the collected dust, dirt, or debris. For those living in areas with heavy pollen or near flowering plants, it is best to clean them frequently. Pollen can settle on glass quickly, clouding the view and compromising the space's hygiene.

      Homes in busier urban or industrial areas deal with a different kind of buildup. Pollution, soot, and smog tend to stick to both the glass and the window frames. Therefore, it is crucial to clean them more regularly. This will help maintain the window's appearance without making it look too worn out.

      How to Open Double-Hung Windows for Cleaning?

      Opening double-hung windows can look more complicated than they actually are. It is advised to check the manufacturer’s guide for model-specific instructions, but the general steps remain the same.

      Opening the Lower Sash

      Start at the center latch and turn it counterclockwise to release the lock. Then slide the lower sash upward by at least 3 inches toward the top section. Then, grip both tilt latches and squeeze them inward to release the holding mechanism.

      Then guide the lower sash by its top edge, tilting it forward until it lies flat in a horizontal position. Once the sash is clear of the frame, the tilt latches can be fully released. This technique will not damage the paint.

      Opening the Upper Sash

      To open the upper sash, slide it downward at least 2 inches, then squeeze both tilt latches and bring it forward in the same manner as the lower one. Once both sashes are tilted in, position the lower sash beneath the upper sash to provide a base of support while cleaning is carried out.

      What to Have Ready Before Starting?

      Before getting started, gather everything needed for cleaning. Here is the list:

      • A bucket, mild liquid soap, or basic window cleaner.
      • A squeegee, a microfiber cloth, or lint-free paper towels.
      • A soft-bristle brush or sponge.
      • A non-abrasive scrubber.

      If the windows have interior grilles, these should be dealt with before anything else. The grilles need to be carefully lifted out and set aside away from the glass and frame edges.  Once these interior grilles are removed and windows are fully tilted in, the cleaning process can begin.

      • Start with the upper sash first. Apply the cleanser to that area and use the squeegee to work across the top section where reach is trickier.
      • Follow that by wiping away any loose debris with a dry cloth.
      • Next, mix water with a mild cleanser, then apply it to the glass with a soft cloth. Work through all the dirt and other residues from cooking that have settled on the surface.
      • Using soapy water, clean the glass in circular motions.
      • Once that is done, use a lint-free cloth or squeegee to remove all the cleaner from the glass.
      • The last step is to apply a light oil or silicone spray to the window's moving parts to ensure they work smoothly. It is important to stick to gentle lubricants here; anything too harsh can damage the window components over time.

      Conclusion

      Cleaning double-hung windows regularly is essential to maintain hygiene and appearance. The windows are built in a way that makes the cleaning job much more manageable. Following the right process with the proper supplies should help keep the windows looking clean and working properly and extend their lifespan.
