I have not cleaned the seats or carpet yet, but in the past I have used Bissel Auto Care Shampoo. It has a brush on the end to scrub with, and it smells good too. As for the trim pieces, you could use Armor All, or some other brand. I don't like to do that because it tends to collect more dust, or maybe the dust is just easier to see. good luck, and happy cleaning!
