I honestly cant remember, it was a lot. I'm thinking around 12 bottles or so. But you saw how filthy the truck was. It definitely cleaned it well. It actually was pulling even more out, but I didn't want to end up spending days going over it again and again haha. The brush and drill really helped things out. It was crazy how much of the stains it was bringing up after just one pass. The shop vac also did wonders, it almost completely dried the seat after a pass as well. I'm going to have to clean it again soon. I've been working out of it 2-3 days per week and i'm starting to get it dirty again on the inside. 🙃
