i believe that it is a last step, i don't think it has any cleaning ability. i am also really happy now that i read their website, where the more and mopre you put on, the better it looks, which is good for me, because i like to wax every week or so, and i usually have to strip the old wax off, and then put more on, now i can just wash, and wax every week. Doing the full detail thing every 2 months or so.
