I just noticed a stain (two straight lines about 8 inches apart) on the passenger seat (color-cashmere) of my C6 that I cannot get out. It may be from a brochure that sat on the seat while the car was in my garage for several days or from the owner's manual leather pouch, which also sat on the seat for several days. I don't remember which one was on the bottom and which one was on the top.
I have tried-Zaino leather cleaner, Dawn, Windex, 303 Protectorate, , saddle soap, WD-40, toothpaste, alcohol, lacquer thinner, acetone, Simple Green, Goo Gone, carpet stain remover, and white vinegar.
I don't know what else to try.
Any and all suggestions would be appreciated. Except for this stain my car is just about spotless.

The 'leather' in a Corvette is protected with polyurathane, Leatherequi is formulated for natural Aniline (uncovered) leather.
It sounds like the ink coating has stained / dyed the polyurathane. You'll need to abrade the stain and touch-up the covering.

I'm not sure it will work but I commonly use the Leatherique Rejuenator Oil and Prestine Clean for difficult stains on seats. It's a powerful combination that should help.
I have often used Leatherique with nice results on some stains too ... but based upon your previous uses, I too suggest as TOGWT in considering a repair is likely needed.

Just an update. We determined that the stain lines were caused by the owner's mauual tri-fold pouch that is vinyl. It was sitting on the seat for about a week. The lesson here- don't leave this thing sitting on your seat for any length of time. The vinyl edges oozed black dye into my cashmere seats, which absorbed the dye.
The local Chevy dealer gave me the name of the tradesman that they use for this kind of work. I brought my car over and they re-dyed my seat bottom to hide the stain. Looks perfect; cost 70$.
