If you want electrical problems, pressure washers work well. Oven cleaner is great for corroding electrical contacts, too.

Do yourself a favour, and live with a clean, but not sparkling engine.

If I need to clean around the engine, I generally use brake cleaner, as it is non-corrosive, doesn't eat rubber, and leaves no residue. You have to use it in a well-ventilated area though. Works well to clean off oil from any oil leaks so you can pinpoint where the leak is from.

Good luck.
