How to Lubricate Window Tracks & Sliding Door Rollers the Right Way

## The Anatomy of Smooth Window Operation Horizontal sliding windows and sliding patio glass rely on bottom tandem rollers gliding across a raised aluminum or vinyl monorail track. When dirt, pet hair, and grit accumulate, rollers seize and drag, scoring the metal track and making opening difficult. ### The Maintenance Procedure: 1. **Lift and Remove Sash:** Most sliding sashes can be unlocked, lifted up into the top frame pocket, and swung outward from the bottom. 2. **Vacuum the Track:** Use a crevice attachment to remove all loose dirt, leaves, and pet hair. 3. **Wipe with Degreaser:** Clean the track with isopropyl alcohol or warm soapy water. 4. **Apply Dry PTFE Spray:** Spray dry Teflon or dry silicone along the track rail and into the roller bearings. Allow 5 minutes to dry to a clear, slick film. 5. **Re-install and Adjust:** Place the sash back into the track and adjust the lower corner screws to level the sash.
