Here is the quickest and less costly first attempt.
Wash car then dry. Using a sponge and distilled vinegar apply to car and rub into surface. Do a small section at a time after a small test spot. If this is working complete the entire car then wash again. Be prepared to wax the car as the distilled vinegar will remove the wax.
The second attempt would be to machine polish to car or to use Scratch X by hand, wash, then wax the car.
Either way a few hours invested will fix the problem.
Good luck and post back if this worked for you.
