I'm sure someone will chime in here but...
Unless they're referring to something more professional at the body shop I would get a Mother's Clay Bar and misting spray and do it yourself. It's not expensive and would probably do the trick. I've used the clay bar in the past as it really gets gunk and impurities in the surface of the paint out pretty well. You should be able to find it at your local auto parts store. Unless the body shop is using some extravagant method I can't see paying them for something you can do yourself with a little elbow grease. Fight the urge to scrape with your finger, though, as you'd be surprised how easy it is to marr a perfectly good finish.
Hope that helps and have a good one!
