Well, I just pulled the engine parts from the crockpot and wiped off the antifreeze with a paper towel and they look pretty good. I'm satisfied enough so I am not going to get the Dawn just yet. I now have the muffler, which was really bad, see my prior post above, in there and will see how that looks tomorrow. If it's still pretty bad after pulling it out tomorrow and scrubbing it with a scotch pad, I'll try the Dawn and post my results.

At least I can put the engine back together now
