Thought id share my method of cleaning the MPE. Its easy, and literally takes minutes.
Needed:
Griots Garage Engine Cleaner
Wheel cleaning brush (BMW wheel cleaning brush used here)
Rag (plush works best)
1.) Simply spray the engine cleaner inside the exhaust and wait 30 seconds
2.) Use the brush like a big pipe cleaner.
3.) Use rag to wipe away. I personally use a plush cloth like terrycloth because its gets into the tinny holes and does a good job getting all the cleaner out.
