P21S Total Autowash
This is probably the most powerful automotive cleaning product in the market today that still offers the famous P21S surface safety. One well-known Porsche restoration specialist swears by P21 Auto wash to get the dirt and grime out of rocker panels, engines and other hard to reach places. This formula is terrific for removing diesel soot and other tough stains that ordinary car wash products just can’t seem to cut. Got a wax or grime build up on your paintwork? No problem. This stuff’s got the mustard.
