1, clean up! Brush off the green skin of the newly received walnuts, and wrap them in toilet paper to dry in the shade. Green husk treatment should be cleaned at one time. If you don't clean it, the juice of the green husk will stain walnuts, so just open the green husk and clean it at one time. Walnuts will have a layer of white-gray dust on their surface after drying in the shade. Some people call it alkali-resistant, others call it hoarfrost. Anyway, this needs cleaning. Some people use pig brushes and others use Wan Wen nano brushes to clean walnuts. Personally, I think Wan Wen Nano Brush is very good. You can try it.
