ask your car dealership if they have experience cleaning stains on leather seats , if they say no ... YOUR SCREWED!...no just KIDDING! If the leather is a sealed leather, meaning it has sprayed on finish (leather will look shiny ) then just keep sponging with mild detergent (there are special cleaners that furniture stores sell just for leather sofas and chairs or the car dealership may carry leather cleaners) If the leather is an analine leather it has little to no finish on it (it may have a wax finish ) this type of leather has a very soft feel and a dull finish. This type of leather needs a proper leather cleaner and is a little harder to clean (it also stains easier) the good news with this type of leather is the natural oils in the leather push the stains and odor up to the surface so with repeated cleaning the stain and odor come out. But I would take the car into your dealership first and let them have a look
Hope this helps
