I've used Griot's Garage Spray on Car Wash all last year. I've never washed my car with water until this last weekend. I did not want to do it then but I wanted to use dawn to strip off the wax and redo it with Zaino. Which turned out nice.
I've used Griot's Car Wash when dirty and Griot's Speed Shine afterwards to gloss up the shine. Both has been great.
