Interior Glass - EO 20/20 (I've tried Stoner's IG and Sprayway not impressed with either. If you use either, follow JimS's suggestion and spray first on your towel, because they are messy)
Clear Plastic - Dampened MF towel
Vinyl - Poorboy's Natural Look. Though it does reportedly have some cleaners, if the vinyl is more than just dusty, I will use a light solution of Quick n Brite
Leather - Lexol's cleaner and conditioner. I have purchased Platinum's (now 4Star) leather cleaner gel and conditioner, but have not yet tried them out.
Carpets - Blue Coral's Dri-Clean or Folex. The key is to use as little product as possible and remove as much of the soap residue as possible.
Cloth seats - I don't have any, but I believe the products above would work OK.
