What You'll Learn
Clean and Lubricate Tracks
1. Use a flathead screwdriver to gently pry each roller from its pocket in the bottom of the door (above). (Rollers are typically held in by friction and the weight of the door.) If they are bent or broken, replace them with new roller assemblies, which cost about $10 each.
2. Scrape any dirt from the wheels, then clean them with denatured alcohol and a rag. Lubricate only with silicone spray (above), which doesn't hold dirt. To reinstall, align each roller's adjustment screw with its access hole and tap in the assemblies with a hammer, using a wood block to protect the wheels. Once they're seated, retract the rollers as far as possible.
3. Wipe the head track and the outside face of the removed head stop with alcohol and spray with silicone. Vacuum loose debris from the bottom track, then clean thoroughly with alcohol. The bottom track needs a more substantial lubricant than silicone; rub it a few times with a block of paraffin wax (above).
