This is probably the most delayed response in the history of message boards, but I saw your question, and you are correct about Dove Soap for fine leather. It was first recommended to me by name by Herman Miller and Cassina furniture companies for use on the Eames Chair and LC3 grande model. You want to look for the original formulation, which contains tallow (essentially just rendered beef fat). During the process of saponification, the animal fats are hydrolized to salts of fatty acids + glycerol. The key point is that leather is an animal hide, and this is the gentlest way to care for it. The poster above was very much mistaken. I apply several thin layers, allowing it to air dry, and then buff it off with a soft cloth. It works wonders. You DO NOT want to apply a leather conditioner to your seats, as that will leave a residue behind. Even a luxury leather care brand like Sefir has caused disastrous results for me, sometimes stripping the color and sometimes darkening it beyond recognition. Dove all the way!
