Tonneau Cover Maintenance Tips

#1. Regularly Check Your Tonneau Cover

A simple preventative measure is to consistently check the condition of your tonneau cover. Some specific things to check for are “scratches, bumps, dents, lodged debris, looseness and corrosion. If you spot anything out of the ordinary, early on, you’ll be able to stop it from snowballing into a costly issue” according to Red Line. Also, it’s important to check for these conditions so you know not to wash or scrub your tonneau cover in those areas to avoid making them worse.

#2. Is Your Hardware Fastened Tightly?

Prior to washing your tonneau cover, be sure to inspect all mounting hardware and clips. This will prevent them from being torn off or causing other serious damage to the cover while you’re cleaning it. In addition to checking the hardware, consider regularly sliding and fully closing your cover to ensure it operates smoothly, even when you’re not actively using it. “… If that’s not the case, lubricate the rails to prevent any unwanted traction and wear.” (4 Wheel Online)

#3. Understand the Proper Way to Wash Them

The proper way to wash your tonneau cover depends on the type of cover, as well as the material of the cover. In general, if you’re washing your cover by hand, use “cold water and a mild soap such as Simple Green, or a specialty Tonneau cover cleaner, and gently scrub the Tonneau cover from the cab to the bed with a soft bristle car wash brush. Then, rinse the cover with cold water again, and dry it with soft cotton cloths or sponges.” (Street Directory)

#4. Avoid Leaving Heavy Gear on Your Cover

It’s important to avoid leaving heavy gear on top of your Tonneau cover for prolonged periods of time, regardless of which type of cover you have. According to 4 Wheel Online, “doing this can cause sagging and/or permanent damage. Always refer to the manual that came with the tonneau cover for weight ratings, and if it is absolutely necessary to stack items, spread them out as evenly as possible.” If you have additional questions, reach out to the manufacturer where you purchased your cover, for advice.

#5. Know Your Cleaning Chemicals

Did you know? Certain silicone-based cleaning products, such as Armor All, can actually deteriorate the adhesives used in specific types of tonneau covers? It’s true! It’s important to never use vinyl cleaners, “such as those made for cleaning the dashboard, as they contain grease and solvents that will accelerate deterioration or fade the color. ONLY if you have a vinyl cover should you use a vinyl cleaner to keep it looking new and working properly.” (Street Directory)


Tonneau covers allow you to protect your truck bed as well as your cargo. They can also safeguard your vehicle against weather elements like messy snow and sleet. Furthermore, they enhance the look of a truck. It’s important to properly maintain your tonneau cover, to ensure it lasts as long as possible.
