Window Maintenance: Cleaning and Lubricating

Windows are one of the most used features of a home, yet their maintenance is often overlooked until they become difficult to open, close, or lock. A little bit of regular cleaning and lubrication can keep your windows operating smoothly, prevent costly damage, and improve their seal against the elements.

🧼 Step 1: Deep Clean the Tracks

The most common cause of a sticky window is dirt, dust, and debris built up in the window tracks and channels.

1
Vacuum: Open the window as far as possible. Use a vacuum cleaner with a crevice tool to remove all the loose dirt, dust, and dead insects from the tracks.
2
Scrub: Use a stiff brush (an old toothbrush works great) and a mild solution of soap and water to scrub out any caked-on grime.
3
Wipe and Dry: Use a clean cloth to wipe out the remaining dirt and moisture. Make sure the tracks are completely dry before proceeding.

✨ Step 2: Lubricate the Moving Parts

Once the tracks are clean, lubrication will ensure everything glides smoothly.

The best lubricant for window tracks and hardware is a dry, silicone-based spray. Avoid oily lubricants like WD-40, which can attract more dirt and gunk up the mechanism over time.

Where to Lubricate:

  • Sliding Windows: Lightly spray the silicone lubricant along the top and bottom tracks.
  • Double-Hung Windows: Spray the lubricant into the vinyl or metal channels on the sides of the window frame.
  • Casement (Crank) Windows: Clean and lubricate the gears of the crank mechanism and the hinges.
  • Locking Mechanisms: A small puff of lubricant into the lock can help it operate more smoothly.

✅ Step 3: Test and Inspect

After cleaning and lubricating, open and close the window several times to distribute the lubricant and ensure it's working properly. This is also a good time to inspect the weather stripping for any cracks or damage that could cause air leaks.
