Other silicon and alcohol-based products can be harmful to tonneau covers and, over time, cause your cover to crack. Pro-TeX is water-based, non-toxic, and non-flamible, offering a safe solution to maintain your new or old bed cover and regain that fresh look. TruXedo Pro-TeX Protectant Spray cleans, conditions, protects, and extends the life of all vinyl tonneau covers. It also works great for tires, dash, trim and convertible tops. Pro-TeX comes in a 20 oz bottle with an easy to use trigger spray handle. Simply spray on and wipe down. Pro-TeX is safe and effective for the uses mentioned above, but it's not meant for absorbent fabric, carpeted floors, or porous absorbent leathers.
