Hi Emily. Welcome aboard! You would probably love this stuff I use called Freedom Waterless Carwash. Its totally safe if used on moderately soiled vehicles to clean them up in like 20 minutes. One bottle last 20 washes and all you need besides it is a couple of microfiber cloths! They even have a version that has carnauba wax already in it!

Anyway enjoy the new Red Beetle. Looks to be in great shape!
