How to Clean Headliner?

I was careless with a pen in my hand as I reached into the back seat, and I dragged the tip across the headliner, leaving about a 5-inch mark. Any recommendations on what to use to clean it? I'm worried about using something that discolors it and it ends up looking worse than it already does. Thanks.

 

Don't know if this tells you anything useful, but here's the description from the Staples site of the exact pen:

Thanks. Yeah, that's my worry - making a larger stain, lightening the headliner color, or both. If that's the alternative, I can live with the thin line.

 

Thank you! Good suggestions.

 

Haven't had a chance to work on this yet, but did want to share the response I got back from Pentel customer service:

Our R.S.V.P. BK90/BK91 pens contain an oil based type of ink.

We have two products that we can recommend for your use. One is Woolite and the second one is Mötsenböcker’s Lift Off. These products are available at most retailer stores.

Please note, our recommendation is not a guarantee of results. Should you decide to purchase and use any of the products, please read all of the instructions prior to use. Repeating the process might be beneficial as well. Work in a safe area and, if a garment, be sure to isolate the stain from any other part of the garment to avoid transferring the ink. You can use a rag or an old T-shirt under the stained area of any item you are working on.

We should also note that if you have already washed the garment or other item, then dried it in a clothes dryer, that could have set the stain.
