I really enjoyed this post. I'll tell you what I use. I hit greasy stuff with mineral spirits to loosen up the stuff in the cracks and crevasses. Then use compressed air to evaporate the residual. Then I hit the parts with POR Marine Clean (spray bottle) and a clean brush and rinse. This stuff will strip the [censored] off a sow and is fine for you and the environment. Just wear rubber gloves and a mask cause it will strip your skin oil and burn a bit in higher concentration. even 10:1 it's amazing.
