It makes for a really, really bad day. So please, know the chemicals you use before you apply them to your top. Your Roadster s top is subjected to the same environmental conditions as the rest of your car. However, where it is easy to see when your Roadster s curvaceous body is dusty and dirty, it is not always easy to see when your top is dirty, especially if it s black or navy blue. One of the biggest factors in top wear is dust in the canvas.
Dust settles into the weave of the fabric and begins to act like sandpaper.
In general, you should care for your top s canvas each time you wash your Roadster. This does not mean you need to scrub it each time, but a good stiff rinsing is necessary. If your top is not dirty, rinse it thoroughly with plenty of cool water. Make sure the shampoo you use does not contain gloss-enhancing oils. If the shampoo contains oils, the canvas will absorb the oil and become a dust magnet.
