Use gunk degreaser-but
Cover electrical connections, fuse area and any component you are concerned about with aluminum foil such as coil on older engines. Make sure engine is warm,not hot and spray engine and engine compartment with gunk or similar degreaser. Ler set about 15 minutes. Spray down (moderate pressure) with water hose to rinse off gunk and grease. Remove foil and start engine and warm it up to dry surfaces. Then wipe down easy to reach surfaces. Been no problem for me. I do it two or three times a year.

(The previous owner didn't take good care of the car) AND the good news is the car runs after tinkering all summer long and I'm shore you guys remember the post M50 won't start thread. as you can tell from my post I'm excited. So thanks everyone who helped me fix the problem. ESPECIALLY Javier for his electronic help.
