Swirls are very shallow BUT numerous scratches on your car's paint. If you park your car under the sun or if you aim a flashlight to your car, and you start seeing cobweb like patterns, swirls yon. Improper washing techniques often cause swirl marks. (Having your car washed by those pesky mall carwash boys is a sure fire way of getting swirlmarks. :D )
Try using your car shampoo first... maybe even try using it undiluted (pure) on the grease spots. If it works, make sure to immediately follow up with a full coat of car wax.
