The invention discloses a deplating solution and a deplating technology for removing a glass NCVM film layer, and relates to the technical field of glass deplating. The deplating solution comprises the following components by mass percentage: 15-35% of EDTA (ethylene diamine tetraacetic acid) tetrasodium, 1-5% of polyamino acid, 0.5-2% of an anionic surfactant and the balance of water. In the deplating technology, the deplating solution is used for deplating the NCVM film layer of a glass product. By adopting the deplating solution and the deplating technology provided by the invention, the technical problems that a strong alkaline deplating solution used for the removal of the NCVM film layer easily causes damage to photosensitive ink after exposure and development and the product yield is low in a traditional technology are alleviated. The deplating solution provided by the invention can cleanly remove the NCVM film layer, has a good deplating effect, and does not cause damage to thephotosensitive ink after
