The reason I am being kind of anal about choosing what to buy is when I bought the car 6 months ago it had a little mildewy smell but after I took a dollar store rubber brush and my 2.5hp shop vac to it I got a lot of crap out. Old french fries, food crumbs, cat vomit, white cat hair (which was EVERYWHERE). The smell went away somewhat but now even when using the dollar general carpet cleaning stuff (the can with the brush attached to it), it still smells a little. I'm thinking I just need to deep clean it of all the years of invisible dirt/bacteria because really it looks spotless besides the stray cat hair here in there. And plus when I wipe the seats and carpet with a napkin it comes up brown on the napkin.
