The dealer left a couple grease spots on my seats and I tried to remove them with some cheapo car cleaner from Walmart and it just faded the stains and left terrible ring spots. What should I use to clean this? I wish I would have just returned the car and told Ford to clean it but I figured they would come right out but of course....they didnt. Would house cleaner Resolve work? Should I use just a cloth or bristle brush?
