Oil marks on leather - cleaning?

[paul chocks]

Just biten the bullet and bought my first Porsche - a 986 Boxster S.

Very happy with it, but having just taken my first female passenger in a short sun dress, I have noticed that she has left some oily residue on the leather. I'm guessing it was moisturiser or sun cream or something similar. Has anyone got any ideas of the best way to remove it - the leather was unmarked before! I've tried a damp cloth which has helped, but is not a complete fix.

Obviously, expecting some funny comments, so bring it on, but a couple of worthwile suggestions would be most appreciated!

Leather cleaner or a diluted down all purpose cleaner, G101, 1001, Flash all purpose cleaner, Daisy or the likes

Wasn't it Carmen Electra who once said she gets orgasms from driving very fast?

But well done for using the car to ferry around female passengers ;o)
