a while ago a friend and i waxed my car, well the part that he did when i left for a sec has some bad build up of the wax, ive powerwashed it several times since then and it hasnt come off yet, what is the best way to remove it

its meguires carnuba wax by the way

 

they sell products that youre supposed to use before you wax your car what it does is remove all the old wax before you put on the new coat. A lot of people say dish soap does the same thing and use it on their cars. Either way it would get rid of the wax build up but then youd have to re-wax the car.

 

Dawn dishsoap, Simple Green or Peanut butter will all break up wax.
