I've notice black smudges and lines are starting to show up on my parchment interior. On the plastic, vinly, and even the leather somewhat. Does anybody have any insight into what is causing this, or how to clean them. I would think they were scuff marks where someone's show has hit or something, but they are in odd places where that wouldn't necessarily happen. Some of them are faint. I was just wondering if anyone could reccommend a method of getting rid of them and keep them away. Or a product, or any help would be great!

Well, I guess no one had this same problem...

Anyway, answering my own post I ended up using a Mr. Clean Magic Eraser and it did the trick- even the black smudges on the backseats- worked like a champ

I was going to say a leather cleaner for the seats and Back to Black for any dark plastics.

I used leather cleaner as best I could on the leather seats, as I didn't know what kind of effect the eraser would have on the leather and I have medium parchment interior so the back-to-black (though I do use it on my weatherstripping, etc) wouldn't have worked- But if any tan interior people are out of luck, magic eraser might help
