All the advice here on engine cleaning is great and works well on newer vehicle however, in the case of an older vehicle like my 59 Morris the engine bay has a lot of electrical connections. I have had some people tell me that the waters ok since it is no worse than what happens if you drive in the rain or on a wet road but, I wanted to get advice on the best way to clean the engine bay. I am planning to do some repainting of the stuff you see in the picture that needs it but, I still would like to keep it clean. Any advice would be greatly appreciated
