Helps if you rub some gunk over the cases first and let it soak in. I take cases out as soon as the washing cycle has finished and dry them off by hand with a rag. I don't use it on iron parts (especially heads and barrels) as the chemicals and the temperature leave some oxidation marks.
Well thanks for the tip Paul. I did try it once with an old Bantam head and you are right, it certainly removes the greasy muck. I was a bit afraid of the chemical in the dishwasher tabs, corroding precious alloy - Bantam heads are a bit more obtainable than SQ4 engine parts!
