I finally started using ONR regularly and love it. However I still do a traditional wash via the two bucket method sometimes if I think the car is too dirty. But, how dirty is too dirty?
In the past I have used it with no pre-soak if the car has been washed within about a week and there was only light surface dust. Otherwise I have started using a presoak.
Currently, my car looks just like the pictures. It stays outside in a carport but has not been washed in three weeks. Is it safe to pre-soak the car then wash? Or does it need to be hit with a pressure washer first?
