Instead of the chemicals I would prefer going for steam jet wash for my car. This saves water as well as cleans the car perfectly. I went to a car wash facility in Noida and heard about this. Loved the outcome. It didn't leave a trace of water. Interested in knowing more, I checked on the product they were using and there was a name which when tracked was of a local manufacturer. Impressed by this manufacturer's product. I wanted to know more and found their website. You can also check them out and see for yourself if chemicals are better or this steam machine was good enough.
