Just got the walnuts, put the water to soak for about an hour, and then use a hard-haired plastic brush, crevice in the place where the brush can not brush, with the brush up to shoot, with the same kind of shooting method when opening the green skin. Then there are residual pulp there with a needle to pick, picked with a brush brush and shoot, completely and thoroughly cleaned up later, dry. The whole process do not see the wind, do not expose to the sun, the operation process to keep walnuts moist. Shade drying is recommended to use waste newspaper or toilet paper wrapped in a drawer, if you put a ziplock bag do not seal. Then more pre-observation of the wetness of the paper, found wet in time to change the paper, until the wrapped paper is no longer wet, you can put a sealed bag (or don't seal, put a sealed bag is mainly windproof, other plastic bags can be) placed in the drawer to continue to dry.
