I know ... Dawn is remarkable soap. I put a squirt of it in a tub of water and clean my black powder revolvers. Don't need anything else, though I have a bar of Ivory floating around in the water so I can work up a lather on brushes for scrubbing stubborn fouling.
Ivory is good because it floats, so I can always find it.
I don't know what makes Dawn so different, but it surely is -- for the better.
