13 Now that the new top is installed, how can you make it last as long as possible? Regular cleaning of your vinyl top is as easy as washing your car. Wash the top just as you would the rest of the vehicle, but avoid cleaners that say they improve gloss. They are good for the paint, but unnecessary for the top. If your vinyl top is particularly dirty, you can use an all-purpose cleaner to break up the grease and film. Use a brush to gently scrub the vinyl, and then rinse thoroughly. After you've cleaned the vinyl, use a vinyl protectant to preserve the color and texture. Your vinyl top will last longer if you protect it from the start. There's not much you can do to reverse damage once it's already been done. Proper vinyl care is as simple as weekly washes, and monthly cleanings with a vinyl top cleaner and protectant.
