I have had some dirt still on an applicator pad after ONR; but that was only when my vehicle was excessively dirty in some -10C weather; so it is a good chance I probably did not rinse the vehicle properly. Here is a shot after using ONR on my car with Meg Gold Class Wax:
Not really all that clean, alot of dust; but then again probably me; not ONR; haha.
Beyond that; I think the mitt and the technique applied plays a greater role than ONR itself.
