I use mineral spirits that you buy at home depot. And yes you should clean the oil off of your chains before you sharpen them with a grinder so that the grinding wheel does not get cloged with oil. After they have soaked I just let them drip dry or blow them off with air compressor if I am in a hurry. I then sharpen them and put them in a coffee can full of oil until the next use.
