Lubricating your windows is essential to ensure that they last as long as possible by preventing wear and tear and creating a smooth open and close. Here’s a step-by-step guide on how to properly lubricate your windows:

Materials Needed

  • Silicone-based lubricant spray (avoid oil-based lubricants as they can attract dirt and ruin the sliding tracks on your windows)
  • Clean cloths or paper towels
  • Mild soap and water
  • A brush or vacuum cleaner with a brush attachment

Steps to Lubricate Your Windows

  1. Clean the Window Tracks:
    • Remove Debris: Use a brush or a vacuum cleaner with a brush attachment to remove dust, dirt, and debris from the window tracks.
    • Wash Tracks: Mix mild soap with water and clean the tracks using a cloth or sponge. Ensure the tracks are completely dry before applying any lubricant.
  2. Apply the Lubricant:
    • Choose the Right Lubricant: Only use a silicone-based lubricant spray as it does not attract dirt and grime and will not damage your windows.
    • Spray the Lubricant: Hold the spray can close to the window tracks and spray a thin, even coat along the tracks. Be sure to get the lubricant into the corners and any other areas where the window slides.
    • Wipe Excess: Use a clean cloth or paper towel to wipe away any excess lubricant to prevent buildup.
  3. Operate the Window:
    • Open and Close: Slowly open and close the window several times to evenly distribute the lubricant along the tracks.
    • Check for Smooth Operation: Ensure the window operates smoothly. If it’s still stiff, you may need to apply another coat of lubricant.
  4. Lubricate Other Moving Parts:
    • Hinges and Locks: For casement or awning windows, apply lubricant to the hinges and locking mechanisms. Spray the lubricant and then operate these parts to distribute the lubricant.
    • Balance Springs (for Double-Hung Windows): If accessible, lightly spray the balance springs or cords to ensure they move smoothly.
  5. Maintenance:
    • Regular Cleaning: Keep the tracks clean by regularly removing debris.
    • Reapply Lubricant: Reapply lubricant every six months or as needed, especially if the windows start to stick again.


  • Avoid Over-Lubricating: Too much lubricant can attract dirt. A thin, even coat is sufficient.
  • Use the Right Lubricant: Always use a silicone-based spray. Oil-based lubricants can attract dust and dirt, leading to buildup and potential damage.
  • Safety Precautions: Ensure good ventilation when using sprays to avoid inhaling fumes.

By following these steps, you can maintain your windows in good working condition, ensuring they open and close smoothly and last longer.
