Do not spray Amazing Roll-Off on the vinyl window. It does not like acids. If your Roadster is new, no doubt you have experienced the frustration of polyvinyl fog. Plasticizers are used in the manufacturing of vinyl to keep it flexible. They are also used in many car care conditioners to rejuvenate vinyl and plastic.
Plasticizers remain liquid, and evaporate with the heat of the sun.
This off-gassing is worst with new cars, and gradually decreases to a manageable level. Severe off-gassing can also be caused by using too much dressing on your dashboard. The best tool to clean your Roadster s vinyl window is the synthetic chamois. Do not use a paper towel, as it can scratch the vinyl. Rinse the chamois thoroughly with water to ensure it is clean.
