I'm seriously considering picking up a used hybrid this week and just wanted to know if it's safe to have a professional automotive detailer "steam clean" the engine bay? My parents and a couple friends have had this done to their cars before and it looked great. I'm not doing this for looks so much but the current owner lives on a gravel road and the engine bay is extremely dirty/dusty. I don't know the extra hybrid powertrain/electronics would pose a problem or possibly be effected? I do plan to call up a couple Honda dealerships tomorrow to get their opinion.
