Choosing the right lubricant for car windows is important for keeping your windows functioning properly. The lubricant helps the windows slide up and down smoothly and prevents squeaking or sticking. There are a few key factors to consider when selecting a car window lubricant:

Type of Lubricant
There are two main types of lubricants used for car windows:
- Silicone-based – Silicone lubricants are slick and long-lasting. They work well for preventing sticking and squeaking. However, they can attract dirt over time.
- Petroleum-based – Petroleum lubricants like WD-40 are also effective. However, they tend to wash away more quickly in the rain and need reapplication.
Many car owners prefer silicone-based lubes since they last longer. But petroleum-based products are useful for a quick fix if your windows start acting up.
Spray vs Oil
Car window lubricants come in spray or liquid/oil formats. Spray lubricants are easier to apply, especially on vertical surfaces. But liquid or oils often last longer.
Consistency
The lubricant’s viscosity or consistency is also important. Thicker lubricants like gels stay in place for longer. But thinner lubricants are better if you want the lube to seep below the window seal. Light sprays are easy to apply but may require more frequent reapplication.
How to Apply Car Window Lubricant
Here are some tips for getting the most out of your chosen car window lubricant:
- Clean the window tracks – Use a vacuum or cloth to remove built up debris before applying lubricant.
- Apply to the window seals – Run the lubricant along the rubber window seals to allow it to penetrate below.
- Spray or wipe along the window track – Coat the entire track the window slides along for smooth movement.
- Remove excess – Wipe away any drips or excess lube to prevent dirt buildup.
- Test window movement – Raise and lower the windows a few times to distribute the lubricant.
- Consider weatherstripping – Use a silicone-based lubricant on the window weatherstripping to prevent cracking.
Take some time to thoroughly apply the lubricant along window seals and tracks. A little lubricant goes a long way for improving window function.
Recommended Car Window Lubricants
Here are some top-rated lubricants to consider for your vehicle’s windows:
| Brand | Product | Type |
|---|---|---|
| DuPont | Krytox GPL 205 | Synthetic Oil |
| 3-IN-ONE | Multi-Purpose Oil | Mineral Oil |
| WD-40 | Specialist Silicone Lubricant | Silicone Spray |

DuPont Krytox GPL 205
The Krytox line from DuPont is a favorite for many mechanics. This synthetic oil lubricates without attracting dirt or dust. It’s super slick and provides long-term lubrication, perfect for car windows. It may require an applicator to apply and doesn’t come in a spray can.
3-IN-ONE Multi-Purpose Oil
This classic mineral oil has been lubricating household items for decades. It works well for car windows too and is easy to find at any hardware or auto parts store. It comes in a range of applicator options. However, it does tend to wash away with rain over time.
WD-40 Specialist Silicone Lubricant
WD-40 is another household name when it comes to lubricants. Their silicone spray is specifically designed for windows and doors. It goes on light to reduce excess mess and lasts for up to 3 months. This is a good option for quick DIY window lubrication.
Dupli-Color Silicone Spray Grease
Dupli-Color’s silicone spray is tailored for rubber, glass, and plastic. It helps lubricate window seals and tracks to prevent sticking and friction. Many users mention this spray goes on white but dries crystal clear and clean.
CRC Silicone Spray
This silicone-based spray works well on metal and non-metal surfaces, making it ideal for window tracks. The spray nozzle makes application easy from any angle. It leaves a micro-thin lubricant layer that lasts up to 6 months.
Conclusion
Using the right lubricant helps car windows function properly by reducing friction along tracks and seals. Silicone-based sprays are excellent choices since they last over time without dust buildup. Brands like WD-40, Dupli-Color, and CRC offer reliable silicone lubricants. For longer lubrication, synthetic oils like DuPont’s Krytox GPL 205 work very well but require careful application. With a small investment of time and lubricant, your car windows will smoothly raise and lower while avoiding annoying squeaking and sticking.
FAQ
How often should you lubricate car windows?
Most window lubricants last 3-6 months or longer. For preventive maintenance, lubricate them twice per year. Lubricate more frequently if your windows start to stick or squeak. Newer cars may need less frequent lubrication than older vehicles.
Can you use WD-40 on car windows?
Yes, you can use WD-40 on car windows safely. However, it’s best to use their specialist silicone lubricant rather than the classic WD-40 formula, which is petroleum-based. The silicone WD-40 adheres better and withstands washing.
What happens if you don’t lubricate car windows?
Without lubrication, your windows will become more difficult to raise and lower smoothly. The movement may become gritty feeling or squeak loudly from the friction. In severe cases, the windows could stop moving properly and get stuck.
Is silicone or teflon lubricant better for windows?
Silicone lubricants are usually the best choice for car windows. Silicone has great adherence, flexibility, and durability compared to teflon-based lubes. Avoid teflon sprays as they tend to evaporate quickly.
Can you use olive oil to lubricate car windows?
Olive oil can work in a pinch to lubricate car windows. However, it’s not ideal and will wash away quickly. It may also leave residue that attracts dirt or dust. Silicone and synthetic lubricants are better options for longer-lasting window lubrication.
Key Takeaways
- Use a specially designed lubricant like a silicone spray to keep car windows moving smoothly.
- Apply lubricant along the window seals and tracks where the window slides.
- Silicone based lubricants tend to last the longest without attracting dirt.
- Reapply window lubricant every 3-6 months for continued protection.
- Brands like WD-40, Dupli-Color, and CRC offer reliable window lubricants.
