The illustrious Mr. Kabbaz recommends Octagon Soap for shirt washing, so I decided to give it a try. Seems the stuff is hard to find. I tried the local grocery and then moved on to the more snobby spots such as Breed & Co. and Whole Foods.
After no luck, I start the Google search. Ah, here's the place https://www.millersrexall.com/
. Not only do they sell Octagon Soap, but really cool stuff such as lucky monkey paws, alligator claws and assorted talismans.
