Steer clear of DIY cleaning solutions. When it comes to leather, you're better off using either water or cleaning products specifically designed for leather. Popular home remedies like baking soda, white vinegar, cream of tartar, and lemon juice can be harsh on delicate leathers and make the problem even worse.
Coconut oil is an excellent conditioner for leather and faux leather material. Use a clean, dry cloth to buff the oil onto the leather or faux leather surface. When the temperature is cold, coconut oil hardens.
