All the above chemicals will completely remove ALL oils in the bearing. Is this what you really want to do? Or, do you just want to clean the bearing? If the later is true, kerosene or varsol is the BEST to use. Both will remove old oils and grease, but leave the bearing still lubricated against corrosion. Although you are going to re-lube the bearing, it is not a good idea to completely remove all oils from the bearing surface.
Be careful with the starting fluid it may eat any seals in the bearing. Perhaps injector cleaning fluid or carb cleaner would be better if you wnt to remove all oils.
