I have been trying to clean both white interiors in the '71 Dart and '68 GTX with relatively ok results. Both are original interiors. I have only used a very mild cleaner and water along with a soft horsehair brush. I've gotten the surface dirt off but they are still a little dingy. Someone suggested cutting down the white wall cleaner I used to use years ago but was a little concerned about doing so. The name of it starts with a "W" (perhaps Wesleys) but it is escaping me right now. What products/methods have you all used to clean original interiors (especially white)? TIA.
