Meguiar's Quik Interior Detailer is a great product for cleaning dirt and residues from the interior. Be sure to follow it with an interior dressing to make it shine; such as, Meguiar's Supreme Shine Protectant, or Meguiar's Natural Protectant.

Two pieces side by side, one changes color. Sounds more like they are different materials or made by different manufactures or different dye lots. You can clean it, but they may not ever be the same color.
