Generally, it is not recommended to take a tonneau cover through an automatic car wash unless the manufacturer specifically states it is safe. High-pressure water, brushes, and chemicals can damage the cover's material, seals, and mechanisms, leading to costly repairs. A tonneau cover is a bed cover for pickup trucks, designed to protect cargo and improve fuel efficiency. The safety depends on the cover type and build quality.
Understanding the Risks
Automatic car washes, especially those with bristle brushes, pose significant risks. Soft vinyl covers can tear or fade, while hard aluminum or fiberglass covers may suffer scratches or seal degradation. Even touchless car washes use high-pressure jets that can force water under the cover, potentially damaging the truck bed or electrical components if the cover isn't fully sealed.
Manufacturer Guidelines Are Key
Always check the owner's manual or manufacturer's website for car wash compatibility. Some modern covers are engineered to withstand car washes, but this is not the norm. For example, retractable covers often have better seals, but still require precaution. Hand washing with a pH-neutral car soap is the safest method to maintain the cover's appearance and longevity.

Proactive Maintenance Tips
If you occasionally use a car wash, choose a touchless system and ensure the cover is securely latched. Afterward, dry the cover thoroughly to prevent water spots or mold. Regular inspections for cracks or loose parts can extend the cover's life. When in doubt, err on the side of caution—hand washing takes little extra time and preserves your investment.
