Vaseline is known for many uses, ranging from removing scratches and getting bubblegum out of hair to pulling tight-fitting rings off fingers and shining leather shoes. Coupled with a silicone bath sealant, vaseline can also do wonders for your windows. If you have noticed a draft in a room, check your windows and find the source of the air leak. Then grab some vaseline and silicone bath sealant and get to work.

  1. 1

    Prepare the window. Clean the window, including the frame. Scrape off any loose flakes of paint so the surface is free of any dirt, dust or debris. Close the window.

  2. 2

    Apply vaseline. Apply an even, generous layer of vaseline along the areas of the window that are touching the frame when closed.

  3. 3

    Add sealant. Squeeze silicone bath sealant out of the tube and onto the frame. Apply a heavier coat in the larger gaps. Make sure you have a tight fit and there are no open areas without sealant.

  4. 4

    Allow drying time. Keep the window closed until the sealant has had time to dry. Refer to the sealant label for specific drying time.

Tips and warnings

  • With enough vaseline, the window should not stick after the sealant has dried. If it does stick, you need to apply more the next time.
  • Be careful when applying the sealant so that excess amounts do not spill out, causing the window to stick.
