What would you recommend for an everyday spray on type engine cleaner? Is it ok to use the selfemulsifying "Gunk" Engine Degreaser on a regular basis? Is there something better? Here is my boggle...I spent all summer detailing the engine, then took it recently for a 6 hour drive in the rain. Just for the heck of it, as I wanted to see what the car was like on chilly wet slick curvy roads. Now the engine is covered with road grime. I don't want to spend all winter detailing it with EngineBrite and tootbrush. It is not a show car, but I want it to look nice when I do display it.
