Im not a detail guy but this has worked for me with the H2 and other cars i owned in the past . do you detail your own seats or pay the car wash guys to do it ?

I've used Lexol Cleaner for lightly soiled seats, medium soiled I use simply green, and heavy soiled simply green with a careful brushing. I always follow up with after simply green by wiping with a clean wet towel. I always follow up the cleaning with Conditioning. I use Lexol Conditioner for normal seats, and Leather Honey for seats that are dry and hard and need moisturizing. This has seemed to work well on my H2s since 2005.
