I came across B101 when a friend shared that wonderful Super Laundry Sauce on facebook. Being fairly frugal and a dyed-in-the wool DIY-er, I just had to try it. I used the first "for dummies" version, since cooking Fels Naphtha doesn't appeal to me, but I grated the soap instead of cutting it up. The resulting glob looked rather ready just a couple of yours after addition of the boiling water, so I proceeded. It was perfect! In use, it reminds me of my early childhood, before we got the automatic washer to replace the old wringer model--clothes and linens that smell like clean laundry! I expect to be visiting here often, and I hope I can contribute something useful.
