I've tried leather cleaners followed by leather conditioners but I don't think their strong enough to remove these stains (dark spots in the creases) and also how do I remove dirt and what not from wrinkles (Because if my seats are going to be wrinkled at least their clean!)?
Is their a safe household product that is a bit more abrasive so I can clean my leather? and also what kind of brush should I use?
