Car Wash Soap Recommendations?

I use whatever Costco has.

Probably the best answer.

Probably the best answer.

Yup! see a lot of Meguiars.

Can't go wrong with these. Gold class is my favorite.

Never used anything better than some leftover Paul Mitchell Shampoo One.
I have not tried Meguiar's - but it's soap; It performs a basic function.
I think the glossifiers and rinse agents in the Shampoo One work magically great on clear coat.
Not Kidding here.

Optimum Car Soap if I'm doing a traditional wash, Optimum No rinse most times.
