no get some proper stuff
There are many different ways to make your own car wash soap. Simply using dish detergent in warm water is one way to make your own car wash soap. Another way is to use 1 cup of liquid dish washing soap and 12 tablespoons of powdered laundry detergent in warm water to make a good car wash soap. For a more eco-friendly car wash soap, you can use 1 cup of a vegetable-based oil soap or multipurpose green cleaner mixed with warm water. Does this help you?
Dawn dish soap works great for hand washing cars, and is environmentally safe as well.
No, according to Consumer Reports, soaps made for household uses (such as laundry or dish soap) can strip protective waxes and coatings. They can cause eventual harm to your paint job.

A good car wash soap, it doesn't leave spots, dish soap will.
Dish soap works great
Soap and water
What do you mean by body soap? Soap that is in bar form, or soap that in a bottle like body wash? Bar soap could pick up sand and grit that might scratch the finish. Body wash is a mild abrasive but I have never heard of anybody using it for washing a car but I assume that a slight clouding of the clear coat is possible. If you have access to dish soap (detergent) it is the best improvised automotive soap.
Dish soap-but don't use it for show cars it can take some wax off
