Review: Great Product - I used this as a pre wash in my Karcher pressure washer dispenser. It gives lots of foam which lasts well, and is simply washed off after 5 mins. After a normal wash the paintwork certainly seems to be cleaner and shinier than when washed without using this first. Would definitely recommend.
