Why is my door panel fabric stained after tinting?

Method 1: Certain types of dish soap or baby shampoo can eat away at the dye of leather or fake leather on door panels.  Additionally, oven cleaner can also leave marks and destroy door panels. Generally speaking, abrasive substances like dish soap or oven cleaners should be avoided, and panels should all be covered or protected somehow. Staining the panels or washing the dye out of panel covers on expensive cars like a Bentley can cost you ten thousand dollars if you’re not careful. If you’re not sure what caused the stain, you can try spraying it again with your slip solution and see if it gets worse. This way you can at least confirm or rule out that the damage is your fault.
