Well, a lot of effort has been expended trying to clean up engines, and just by accident I happened on a good way. I bought my wife a "SCUNCI" steam cleaner to clean some articles in the house, and decided that I needed to check it out. I put some water in it and let it warm up (about 5 minutes) and pushed down on the release button. "WOW" this little gadget has some good pressure and the grease was flying off. I agreed to let her use it during the week if I can use it on the weekend. If the temperature warms up some this weekend, I plan on using it some more. FLATHEAD
