For weekly washing,
standard car wash soap is recommended. However, if you'd like to remove old wax/polish/bugs, detergents from your paint
before applying a coat of polish and then wax I highly recommend a
dish soap.
I've been detailing cars for nearly 10 years now. Good ole Dawn dish soap works the best for stripping old wax and debris from your vehicle.
