The feeding is performed by releasing trapped solvents and restoring original moisture into the vinyl. Some vinyl surfaces may need several coats or applications in order to restore the original luster to the vinyl finish. Always allow the solution to remain on the surface of the vinyl for a few minutes before wiping or buffing. Vinyl surfaces should be cleaned on occasion with normal car wash solution. In some cases where there is noticeable build up of previous layers of vinyl dressing, use a vinyl and rubber cleaner before applying the vinyl treatment.
Some conditioners contain a sunblock for UV protection.
In any event, the care and maintenance of vinyl finishes requires continual attention because of its exposure to various forms of deterioration.
