Thing is I live in a very dusty area and because I that I need to wash the car 3 times a week if I want it clean (it's black saph). The thing is that the car is not dirty, just dusty.
Washing the car 3 times a week is killing the paint, adding swirls and so on and just because of the dust.
What would you advise me do in this case?
Thanks in advance!
