the secret of Leatherique as maintainance vs restoration, is the stuff they use in the mixtaure actually helps the leather to breathe and cleans the pores (yes, leather has pores; thats how it accumulates dirt). No dount Oxi will clean the leather, the question is whether it will damage it. My wheel and leather has 220,000km on it and looks virtually new!!. Going to redye M3 seats I installed in fall so they'll look as good as rest of leather... Look @ my original seats for sale (in FS section of course). See how good they look...and they've been sitting in my garage for 6 months.....
