Any tips on cleaning the gray interior liner?

[RonKorakas]

I just got my Model 3 back from the shop, and there was black residue of some sort on the liner. It looked like electrical tape residue. I didn't know what it was, so I stupidly tried to clean it with a towel, and I got most of it off. But there's still some light spots and I'm afraid to use anything wet. Any tips, or products that will work wonders to clean it?
Something that won't leave a "wet stain" after?

I would make it the shop’s responsibility. This is unacceptable.

I had some stains in the same area and I used this fabric cleaner from Mckees 37 and it worked well. The key to avoid a "wet stain" is to spray the product onto a microfiber towel (do not spray it directly onto the area) and then lightly blot the area using the towel. Then "dry" the area with another clean, dry microfiber towel.

Good luck!

I found similar stains on my headliner. (I don't know what they were or where they came from.) I found using baby wipes, as instructed in the following video, worked very well, though I had to work at it for a while.
