The different types of convertible tops
There are products designed specifically for the cleaning of convertible tops.
Various companies, which make the material for American and European convertible tops, and manufacturers of retractable truck bed tonneau covers recommend using products designed specifically for convertible tops.
On fabric tops — It is recommended that professionals use a chemical with a fluorocarbon repelling system.
Such a chemical will bond with the fabric and repel liquid and dirt while at the same time providing ultraviolet protection. Look for products that do not contain silicone, Freon, or chlorofluorocarbons (CFCs).
On vinyl tops — A fluorocarbon repelling chemical is not necessary because vinyl is not porous.
Instead, use an approved product that protects and beautifies the top. Such a product should have ultraviolet blockers that help reduce the cumulative effect of sunlight exposure.
It is important not to use products that contain silicone, petroleum solvents, or CFCs, all of which can have a negative impact on the vinyl material.
