i'm thinking of getting my '98 VW detailed, inside and out. the place where i get it washed does a nice job w/ that, so i inquired about detailing. everything sounded good except for one thing: the engine cleaning. they want to steam out the grease and grime, plus apply some kind of treatment to the belts and hoses. i'm skeptical. this struck me immediately as a bad idea, as in it'll do more harm than good, but i'm open to opinions. anyone ever had the engine steaming etc. done and have anything to share? better yet, anyone know the inside scoop on this stuff?
