In the past, I usually take my old G35 to ESSO Touchless wash.
I'm really concerned about the acidity of the soap used by ESSO. Will that do any harm to my EX, especially since I have the clearcoat on it that heals itself from minor scratches ? Some people are claiming that ESSO uses really low ph so that it can be washed away with the water, while others have claimed that it doesn't do much harm to the car.
Any inputs from you guys here ? I'm living in Toronto, Canada... not sure if US has the same ESSO/EXXON touchless wash tho.
