blue ink on grey leather!!!!!

have a customer that had a pen explode in his truck leaving a big blue stain, any suggestions on how to get it out?....its about a week old now he says.Tok his number and said that i'd get back to him on it.

Ouch.I had thet once on my cloth seats and vinyl.I simply used rubbing alcohol and hair spray to get it out.Worked like a charm.Just make sure that you dont let the excess runnoff into another area.
