How do you remove a black eyeliner mark on a light gray upholster car seat?

So far the best thing I have found that has never failed in removing anything from carpet is called Primis carpet and upholstery cleaner I bought at Big lots but you can probably find it other places. Never once so far fail me and I have had some bad stains. Keep upright when spraying to make a good foam let sit respray and scrub with a brush blot respray and scub with towel.
