Care and Maintenance

BAK Flip tonneaus are made from durable materials and require simple care to ensure a long life of performing well and looking great.

Cleaning the Top (Washing)

Standard automotive soap and water with a soft sponge or cloth is recommended for cleaning. Shammy dry to keep the finish polished and brilliant. Wax is NOT recommended as it tends to fill in cracks and crevices, which may affect the textured panel finish. Do NOT use any harsh cleaners or abrasives.


It is recommended that you periodically check your cover is securely attached to your truck bed. Inspect the clamps and front mounting bolts to ensure they were properly installed and have not come loose or knocked out of adjustment during operation. Covers that are used with high frequency or that are subject to the vibrations and impact from rough roadways can cause the cover to require adjustment.

Lubricating the Latches

It is recommended that you periodically inspect and service the latches on each panel. Clean away any excess dirt or grime and lubricate with silicone spray. Ensure the latches move freely in and out to properly engage the side rail and provide proper performance with optimum security. Be careful not to overspray the cover. Wipe away any excess around the latch location.
