1. Manual treatment mainly uses abrasive cloth, scraper, hammer chisel, steel wire brush, waste grinding wheel and other tools to remove rust, scale, welding slag, dust and other surface dirt by manual grinding, chipping and brushing.

2、机械处理更常用的有风（电）动刷，除锈枪，抛光砂轮及风（电）铲等工具，借助机械力的高频冲击与磨擦的作用除锈和清除氧化皮旧漆等污物。

2. The most commonly used tools for mechanical treatment are wind (electric) brush, derusting gun, polishing grinding wheel, wind (electric) shovel and other tools. With the help of high-frequency impact and friction of mechanical force, they can remove rust and dirt such as oxide skin and old paint.

3、喷射处理是利用机械离心、压缩空气、高压水流等为动力，将磨料、砂石、 钢丸抛射到铁艺制品的表面，冲击和磨擦掉氧化皮、锈痕、旧漆、型砂等。

3. Spraying treatment is to use mechanical centrifugation, compressed air and high-pressure water flow as power to shoot abrasive, sand and steel shot onto the surface of iron products to impact and rub off oxide scale, rust mark, old paint, molding sand, etc.

4、 化学处理是利用特殊配方的酸性溶液来浸、溶铁艺制品，通过化学反应来除净氧化皮、锈痕、油污，即所谓的“酸洗”。

4. Chemical treatment is to use the acid solution with special formula to dip and dissolve the iron products, and remove the oxide scale, rust mark and oil stain through chemical reaction, that is, the so-called "pickling".
