Those are some serious grease stains but...is that untreated knotty pine on the cupboard doors? I would agree with you that this material is totally unsuitable to any kitchen let alone a rental unit. I seriously doubt that that will just "buff out".

Incidentally, did you happen to notice if any of those stains were there before you occupied the unit? You've also been in that unit several times before in the past. How was the kitchen finished previously?
