Hand washing is the best way to keep the vehicle clean. Though some vinyl manufacturers say it’s safe, we recommend avoiding high pressure systems as some use higher psi that could lift or damage the vinyl. Never wax your vehicle!! Vinyl needs to breathe, and waxing will seal the vinyl and actually cause it more harm than good. Instead, use a vinyl polish. If you have a vehicle with window graphics or window perforated graphics, you want to avoid using an ice scraper. Instead, turn on the defroster and use a soft brush to do the job.
