Why one product for every surface is wrong
All-purpose interior cleaners are formulated to be safe on the most common surface in a mass-market cabin — hard plastic. Used on aniline or semi-aniline leather they strip the finish and dry the hide; on Alcantara they flatten and mat the pile; on open-pore wood they leave a sealed, shiny film the factory never intended. The reason a professional interior looks factory-correct afterwards is not a better single product, it is the refusal to use one.
