The invention discloses a metal product surface treating technology, and relates to the technical field of metal product treatment. The technology comprises the first step of alkali washing and the second step of activating liquid soaking. By means of the adopted treating technology, corrosion resistance of produced metal can be effectively improved, and the service life of metal products is prolonged. The technology carries out alkali washing on metal products, mineral grease sucked to the surfaces of metal products which cannot be removed through conventional methods can be effectively removed, in practical operation, it is found that surface activity of treated metal is enhanced, the wall hanging rate of paint is improved when paint is sprayed, and the surface acid-base corrosion resistance of metal products soaked in activating liquid is greatly improved. 本发明公开了种金属制品表面处理工艺，涉及金属制品处理技术领域，包括以下步骤：（1）碱洗；（2）活化液浸泡；本发明采用的处理工艺，能够有效的提升制得的金属耐腐蚀能能力，提升了金属制品的使用寿命。其中，本发明对金属制品进行碱液清洗，可以有效的除去常规方法无法除去的粘在金属制品表面的矿物性油脂，并且实际操作中
