... from my experience, if you've got a very slow leak that lasts a long time you can get oily grime deposits on things like sub-frames, heat shields and exhaust components that don't get hot enough to actually burn the material away.
I'm not so sure I'd go with brake cleaner for this type of mess myself. In my case I give a liberal application of "Oil Eater" ... a detergent spray I found at Costco ... on a slightly warm engine. I let the stuff penetrate for a few minutes and then hose it off. IME this stuff does a very good job of cutting through the grime so it comes off easily. I've never found brake cleaner to be a very good penetrant ...
Assuming that you have addressed the leaks, I would expect that a thorough cleaning with the Oil Eater will resolve the stink issue ... at least it will allow you to localize things a little better ...
