I've got all the tools, techniques, products, etc needed for detailing the exterior of my car but I haven't done much research about how to detail the interior of a car. I have a 2008 Lancer GTS and there's a lot of fading going on on the faux carbon fiber and the leather wrapping around the steering wheel. I also have some stains in the carpet/upholstery, but I'm not sure what any of them are. Also, the upholstery is very stubborn, especially the floors of the car. If anything is stuck in the fibers, it takes a good amount of effort to get it out. If anyone could please point me into the right direction to make my life any easier, I would greatly appreciate it. Thanks!
