Did you fall out of a plane and hit your head. What do you think you use. I dont know maybe non-leather cleaner. Just go to your damn auto store and pick up something on the shelf that says "for dashboards". As far as which type to use get the one thats most expensive or a brand that is known for quality like hmmm i dont know maybe ARMOR-ALL. Sorry for being so pushy but geez did u really feel like you need this advice like you couldnt have figured it out on your own. Some people are empty chairs. Im in a bad mood right now forgive me.
