I would not wax or polish the car until the solvents in the paint dissipate and cure. (usually 3 months to a year) Mild soap and lukewarm water is only needed.
If you polish and wax a freshly painted car, you may cause clearcoat and/or base coat delamination.
If IR lamps were used to partially cure, the time can be reduced. Either way, I would not polish/wax for at least a year in this climate.
What paint system was used?
