文玩核桃和金刚菩提的原生态差不多，下树后外面都是厚厚的青皮，钢丝刷也是清理核桃使用的利器，同时在核桃上使用钢丝刷的话，不仅仅满足于核桃的青皮清理，钢丝刷也可以用作核桃的打底使用，核桃体积大，用钢丝刷打底效果也很好，打底的同时钢丝刷也促进了核桃包浆的快速形成，一举两得。
The original ecology of Wenju walnut and Diamond Bodhi is similar. There are thick green skins outside the trees. Wire brush is also a sharp tool for cleaning walnuts. At the same time, using wire brush on walnuts is not only satisfied with the cleaning of walnuts'green skins, but also can be used as the base of walnuts. Walnuts are large in volume and use wire brush. At the same time, the steel wire brush also promoted the rapid formation of walnut pulp, killing two birds with one stone.
