I've found a great cleaner for the engine bay is "oil eater" but just don't get it on glass or use on HOT aluminum. It'll even take oil stains off your drive from 20 years ago without scrubbing and it is nontoxic and biodegradable. I can't get in Saudi or the Philippines but the wife and I check at Costco every trip back to see the kids.
