So I got my '06 Prius a couple weeks ago, and the dealer didn't exactly "detail it" well. There were still some stains on my floor mats and a couple on the seats. I tried vacuuming and shampooing the floor mats, but nothing came of it. Today I saw Armorall fabric wipes. They work FANTASTICALLY on my carpets, floor mats, and cloth seats, and my Prius has the cleanest interior in town now. Cost: $2.99 + tax
