Got to agree. The crockpot and antifreeze method is the best I have ever come across to spruce up an engine.

I use enough antifreeze so the engine is well submerged. Put the pot on the low setting and let it work overnight.

The next day a good brushing with a toothbrush or any fairly stiff small brush is all that is needed to get an engine in like new shape.

The only down side I have found so far is that I have had to buy my wife a new crockpot when she found out where hers went.
