One other thing on the "crockpot" engine cleaning.... NEVER put it on high..... the result will be an engine that has turned a dark grey color and cannot be polished out!!!! (how do I know this????) Low temp overnight is all that is necessary.... and I'll just echo about the safety issues..... haven't tried the Dawn stuff... might need to look into it as it does seem a bit easier...
