It was still useful for me, I know to go to the dish detergent aisle now, not the laundry aisle.  I have looked all over at Walmarts in Canada and they don't have it.  I will check next time I go to Detroit. (put on a bullet proof vest?) I have tried the slow cooker and antifreeze thing once with ok results, but don't want it to turn black, so I will try the Dawn as soon as I can get some.  Carb cleaner results were kind of so so with me.
