Or wax and grease remover and clay bar, if you get to crazy with the solvents you might be removing color with the wax…
I would try spray detailer. Hose it down liberally, don't let it dry but let it soften and work through the dried, hardened wax. Use the abrasive, side of a microfiber detail towel to remove the wax, then turn the towel to the soft side for polishing using more detail spray as needed.
I still use Turtle paste wax after I clay bar on all 3 of our car/trucks. The 56 gets Harley (nothing to do with HD) Wax on the dash. Some habits are very hard to break.
I still use paste wax just because dad said it was “better than the new fangled liquid stuff these folks are trying to push off on you.” This was in the early stages of the liquid wax revolution in the early 80’s.
This is what I do. It worked on a friend's pickup where they'd left the dried wax residue on there for a couple years.
i liked blue coral two step it took an afternoon to apply but a year later it would not even get wet when it rained now i can not get wax to bead water after two weeks
When I buff a car that still has emblems mirrors & door handles (meaning I didn't just paint it) I use my pressure washer to get the dried compound from around & in between. I would think it would remove dried wax just as easily. Get it wet, let it sit for a minute & go for it. Obviously you have to use common sense & not set it on the highest setting or hold it an inch from the surface.

Soft tooth brush helps in tight areas dipped in wax and grease remover, then micro fiber towel to clean the area.
If its excessive: Wax and grease remover (panel prep), mineral spirits, naptha. Be sure to test on paint. I do like paste wax This fall I waxed daily driver truck with 5 different waxes I had on shelf, different panels, to see what lasts the longest.
I must be really out of touch... As I remember it, back in the old days you were suppose apply the paste wax with the applicator to a 3' x 3' area, let the wax dry, then buff it to shine with a dry soft cloth. If you got it too thick, or spread it too far over too large of an area in a few places, you may have had to rub it a bit harder. It sounds to me like you spread the wax too far before you buffed it to the shine. Get a clean soft cloth, and rub it a bit harder. the next time, you won't spread it over too large of an area and let it dry so much before you buff it out.
