Don't many nonpolar solvents leave an oily film. As in they don't all evaporate fully? At least turpentine and xylene leave a smell that just doesn't seem to disappear.
My impression was that the polar solvent was meant to flush out any residue of the more potent nonpolar solvents. Though that's just what I've read somewhere so I don't really know.
But, far more importantly, DO NOT USE PETROL (OR GASOLINE IN THE US)!!!
Yeah I need to stop using white gas. It's great for multifuel burners but sloshing it around jars has started giving me the creeps.
Good thing ceramic apeed came out with their UFO cleaner. I hear it's quite effective and completely non flammable.
