First step: soaking: first of all, we have to prepare a clean and oil-free container, next we have to pour our pure water into the container, of course, at home you can also use tap water instead of mineral water. Put the pure dried sea cucumber into the container with enough water, more observe the water quality every 6-8 hours to change the water, insist 48 hours, (48 hours after the selection of sea cucumber, if the hardness is still strong, you can continue to stay for one more day to soak,) the whole process does not contact with the objects with grease and chemical.
