use 303 aerospace cleaner, it has done wonders for many dirty interiors. Just mix to the right dilution and spray it on, use a stiff brush and then a towel to dry, it has done a fantastic job on some of the donated cars that the dealership has gotten in, and they usually are super dirty. It is ph balanced and does not eritate the skin, and its enviormentally safe. Plus you can change the dillution and use it on anything, I really like the stuff.
