Folks:
I would strongly recommend against using TCE or its chlorinated brethren. As one in the environmental engineering profession, we run into problems with TCE repeatedly. IT IS NOT GOOD STUFF. Other less toxic and less persistent alternatives are available and have generally been substituted in most industrial degreasing operations. If you must use a non-citric acid based solution to degrease a part, at least use a non-chlorinated organic like xylene. I second the use of kerosene or diesel as a readily obtainable and reasonably aggressive degreaser for removing heavy grease accumulations.
If you insist on using any of the chlorinated organics, make sure you use a respirator and dispose of the residual appropriately. This won't be easy.
