Hello George,

I am assuming you are talking about a vinyl Extang tonneau cover. Cleaning your Extang tonneau cover is super easy and a great way to keep it looking sharp for the long haul. Start by giving it a good rinse with a hose to knock off any loose dirt or debris. Then, mix up a bucket of mild soap (like dish soap or car wash soap) and gently scrub the cover with a soft sponge or brush. Make sure you get around the seams and edges too. Just avoid using anything harsh like bleach or strong cleaners, since those can damage the material or fade the color. After scrubbing, rinse it off really well to remove all the soap, and dry it with a soft microfiber towel to keep it streak-free.

Once it’s clean and dry, this is the perfect time to protect it. Grab a bottle of Extang Tonno Tonic Protectant Spray # EX1181 for Vinyl Tonneau Covers and apply it evenly across the surface. Not only does it restore that deep, rich finish, but it also adds UV protection to help prevent fading and cracking over time. It’s basically like sunscreen for your tonneau cover, and it really makes a difference! A little regular care like this goes a long way in keeping your cover looking great and lasting for years.

If you have a different kind of tonneau cover please let me know.
