How to Clean, Protect, and Preserve Your Truck Bed Cover

Posted on June 7, 2018

Whether you have an A-series, M-Series, or E-Series Roll-N-Lock tonneau cover, it’s important to start protecting it from Day 1. This will help extend the life of your cover and ensure it continues to operate smoothly year after year. When manufactured, truck bed covers are treated so that they’ll repel water and other contaminants like dust and sap, but eventually, that initial treatment will wear off, and leave your cover vulnerable to weather and other environmental hazards.

When rain and regular cleaning begin to leave puddles or damp spots on your truck bed cover, you know that it’s time to start treating and protecting it. How long do you have before your initial treatment dissolves? It really depends on where you live, how much sun, rain, or snow your truck is exposed to regularly, and how much road-time versus garage-time your truck is seeing.

Black vinyl-topped tonneau covers, such as the M-Series, absorb the sun instead of reflecting it, and tend to need care pretty quickly. They heat up easily, which amplifies the effect of any contaminants. In damper climates, truck bed covers can develop mildew or mold if not cleaned and conditioned regularly.

It’s important to pick a good product to protect your truck bed cover. For starters – you should wash your vehicle with a premium automotive detergent once a week. When washing, take the lid off the tonneau cover housing, check the drains, and make sure you clear out any debris and sticks. After washing, you should apply a premium vinyl cleaner to your tonneau cover to remove dirt, grime, and mold.

Fortunately, every new RNL truck bed cover comes with a free 303 Aerospace Protector (ASP). ASP was originally developed by NASA to protect materials against UV damage and help them maintain elasticity during extreme conditions. Unlike over-the-counter treatments and sprays, which eventually will eat away at the adhesive under your tonneau cover, 303 ASP will remove dirt and mold while leaving a coating of special moisturizers that penetrate the surface. Spraying 303 protectant on the tracks of your tonneau will also help your cover run smoother and faster.

When you apply 303 ASP to your truck bed cover, make sure you do so lightly, so you don’t saturate the vinyl. It’ll help to protect it from from UV rays, airborne pollutants, acid rain, and other contaminants. Your cover will repel water as effectively as it did when you first got it, and you’ll notice how supple and new it looks, no matter what you put your truck through on a daily basis. 303 ASP is effective on any vinyl tonneau cover, and other parts of your truck, too, like vinyl roof coverings, vinyl seats, dashboards, or the trim. It also helps to preserve and protect rubber and fiberglass, too.
