Having sliding doors that operate smoothly is important for functionality and reducing wear and tear. However, over time dirt, dust and grime can build up in the tracks causing the doors to stick and bind when opening and closing. Using the right type of lubricant helps reduce friction and allows the doors to glide easily again.

Types of Sliding Door Tracks
There are a few main types of tracks that sliding doors use:
- Aluminum – Most common. Made of extruded aluminum and attaches to the door frame.
- Wood – Used mainly for decorative purposes on wood framed doors.
- Vinyl – Plastic tracks that are durable and low maintenance.
- Steel – Very heavy duty for large sliding doors. Usually galvanized or stainless steel.
The specific track material will impact what lubricant works best. Metal and vinyl tracks have slightly different needs than wood tracks when it comes to lubrication.
Choosing the Right Lubricant
Here are some tips on selecting the best lubricant for each sliding door track type:
Aluminum & Vinyl Tracks
- Use a dry lubricant such as a spray powder graphite or silicone spray. These coat the track without attracting dirt and dust.
- Avoid oil-based lubricants like WD-40. While they reduce friction at first, they quickly attract contaminants.
- Lithium grease can work well for a longer lasting lubrication solution.
- If tracks are dirty, clean them first before applying lubricant.
- Apply lubricant sparingly. Too much can become gummy and worsen stickiness.
Wood Tracks
- Look for lubricants specifically made for wood like paste wax or silicone spray.
- Avoid petroleum-based lubricants as they can stain or damage the wood over time.
- Wipe a thin layer of paste wax evenly over the track and buff off excess.
- Reapply wax 2-3 times per year for continued lubrication.
Steel Tracks
- White lithium grease is a good choice for steel tracks.
- Dry PTFE lubricant sprays can also reduce friction.
- WD-40 works on steel tracks but requires frequent reapplication.
- Clean tracks thoroughly before lubricating to prevent gumming up the grease.
5 Best Lubricants for Sliding Door Tracks
Here are 5 top-rated lubricants recommended for keeping sliding door tracks operating smoothly:
| Lubricant | Type | Key Features |
|---|---|---|
| Dupont Teflon Non-Stick Dry-Film Lubricant | PTFE dry spray | – Creates a dry, long-lasting lubricant coating – Reduces friction and binding -Won’t attract dirt or dust |
| Blaster 9-Ounce Advanced Dry Lube | Dry PTFE spray | – Formulated for metal and plastic – Provides a clean, dry lubrication – Protects against rust and corrosion |
| 3-IN-ONE Multi-Purpose PTFE Lubricant | Dry spray lubricant | – Reduces friction on metal, wood, vinyl, plastic – Prevents sticking and binding – Protects against wear and abrasion |
| Tri-Flow Superior Dry Lubricant | PTFE-based spray | – Creates a dry, wax-like coating – Provide long-lasting lubrication – Repels water and dirt |
| Howard Products Butcher Block Conditioner | Wood paste wax | – Formulated for wood surfaces – Conditions and lubricates – Leaves a protective wax coating |
Always follow the manufacturer’s recommendations when applying any lubricant. More is not better when lubricating tracks. Apply a thin even coating and reapply as needed.
DIY Homemade Lubricants
If you don’t have a commercial lubricant available, here are some household items that can work in a pinch:
Graphite Powder
The key ingredient in many dry lubricants. Apply powder directly to track and spread evenly. Allow to dry before using door.
Bar Soap
Rub a bar of soap lightly over the track to leave a thin lubricating film. Ivory and other non-moisturizing soaps work best.
Candle Wax
Rub a candle up and down the track to coat it with a thin layer of wax. Buff lightly with a clean cloth.
Vegetable Oil
Oils like olive and coconut oil can lubricate wood tracks. Wipe a thin layer on and wipe away any excess.
Application Tips
Follow these tips when applying lubricant to sliding door tracks:
- Clean tracks first – Use a degreaser to remove built-up grime before lubricating.
- Less is more – Apply lubricant sparingly and wipe away any excess.
- Spread evenly – Run the lubricated door back and forth to evenly distribute the lubricant.
- Buff wood tracks – Lightly buff wood tracks after applying wax lubricants.
- Reapply – Lubricate tracks every few months or when doors become sticky.
Lubricating Sliding Door Wheels and Rollers
In addition to tracks, sliding door wheels and rollers should also be lubricated for smooth operation. Here are some tips:
- Clean wheels first to remove buildup of dirt and debris.
- A spray-on lubricant aimed directly at the wheels/rollers works best.
- Lithium grease can be used for a longer lasting lubrication.
- 1-2 drops of oil on each wheel can help but avoid over-oiling.
- Spin the wheels after lubricating to evenly coat all sides.
Warning Signs a Track Needs Lubrication
Here are a few signs it’s time to lubricate sliding door tracks:
- Sticking, binding or resistant when opening/closing doors.
- High-pitched squeaking or squealing noises.
- Visible dirt and debris buildup in tracks.
- Rollers/wheels not spinning freely.
- Doors require extra force to fully open or close.
Addressing these issues quickly by lubricating tracks and hardware can prevent more costly repairs down the road.
Conclusion
Regularly lubricating sliding door tracks helps keep doors gliding smoothly and reduces wear. The best lubricant depends on the track material – dry sprays work well for metal, wax for wood tracks. Avoid over-application and wipe away any excess lubricant. With the right lubricant and proper application, sliding doors will operate easily for many years.
