I really think it depends on type of dirt (clay, granite, sand). I used to pre-rinse with water, pre-treat with ONR, and then clean each panel using MF mitt and an extra rinse bucket. The Benz still developed fine scratches from it. In one instance I washed the car one day after I used ONR and behold the marring appeared. In my experience they were just a tad more visible than marring from hand washing with water and soap.
It won't leave deep scratches but it's not any less marring than using water/soap IMO. I believe these products have a filler or something to hid the fine marring.
Perhaps I should have used a grout sponge instead
