When making bread or other yeast products, getting dough on your hands is one of the inevitable consequences. Theoretically fully developed dough should be considerably less sticky than under-worked dough, but that doesn’t mean it won’t be sticky at all. Washing your hands will help some, but you’ll be scrubbing under the water for a long time. The trick is to rub your hands together over a garbage can to get most of it off. If its too sticky, get a little flour on your hands and keep rubbing. The flour will dry it up and allow it to ball up ad come off. The remaining dough will come off with a light hand washing.
