I've used raisins a few times. You are right they are often covered with a thin film of oil for preservation. My first step is a vigorous rinse a couple of times. Then overnight soak followed by a blend with a food processor or ? vitamix. Then put them in a mesh bag. Not sure if that helps. Once I noticed a sort of fatty film or ring at the mouth of the carboy. I was a little concerned but after a second racking it wasn't an issue.
