Degreaser that won't harm wax?

[nickstradamus]

Looking at adding a light degrease on the bottom half of the car to the wash routine to loosen up road grime prior to a rinse and wash with the Gilmour. However I don't want to hurt the wax job in the process.

Anyone have anything they use? If possible, would like to be able to get it local instead if ordering online. But that isn't a deal breaker.

Searched everything and most info is for engine bays. Thoughts DA? Thanks!
