What would you use to clean the interior ie. inside door trim. It's faded to two/tone. Is there a way to clean or re-paint ?

what year/make/model is the car? Your best bet would be to use some sort of interior die/stain to make it all one color again since it being sun faded, it won't be able to be cleaned off. Try an autoparts store for the die, they should have a small selection of colors to choose from.

vinylex by lexol is a very good produuct.

VHT Vinyl dye will do the job. Summit racing sells a few colors, but other web sites have a wider variety (I think they make about a dozen colors). If you google "vinyl dye" you can find sites where people have used it and describe what they did as well as other vendors.

I am debating changing the color of my interior altogether, and this is the product I plan to use.
