Ideas to remove oil from leather doorcards

[BigTartanJudge 0]

Hi guys,

Unfortunately my ignorant flatmate has been an ars*. He laid my oil cooler on top of my leather doorcards when moving stuff overnight. Some oil has leaked over one of the cards. Any ideas on how to go about cleaning or removing the oil? Any ideas much appreciated
