Is the auto wash solution or a concentrate? Dilution? Use with Karcher 2400 with black nozzle and siphon at max?

Yes, this is an auto wash solution and concentrate. I mix the amount recommend with water in the Karcher washer. The mixing amount is measured by filling the small upper chamber and pouring in the machine. It is enough to do a fairly large auto. I am not familiar with the 2400; therefore, I can only offer limited instructions. I use another type karcher.

Amazon is saying this can't be shipped to my address. Is it illegal in California for some reason?

I don't know about this particular product, but I did live in California. The main reason that this product can't be shipped to your state is because Califorinia health agency is a consumer health protection watchdog that goes through every product imaginable and will not allow any products to be used because they may be known to cause cancer in animals or humans. California is more strict about cleaners, pesticides, auto exhaust than any other state. Hope that helps.

My pressure washer mixes a 20 to 1 ratio itself. So should I dilute this quart to five gallons first, and then fill the tank with it? Thank you.

I have the 1600 PSI Ryobi model that automatically dilutes at 20 to1. I just got an answer about this from a Ryobi agent: Agent, "You do not need to dilute the pressure washer detergents in this pressure washer. It will automatically dilute as it comes out of the pressure washer."

I can not find this on their website. Do you mix this with water as directed, then put that in the soap tank on your pressure washer?

Yes, the mixture is 20oz of water to 1oz of soap.
