The invention discloses an environment-friendly chemical polishing solution. The environment-friendly chemical polishing solution is characterized by being prepared from the following materials of, by weight, 30-100 parts of a citric acid class polishing solution, 20-80 parts of polyethylene glycol, 10-30 parts of sodium dodecyl benzene sulfonate, 5-20 parts of p-hydroxybenzoic acid, 1-3 parts of trisodium phosphate, 0.6-1.3 parts of benzene sulfonic acid sodium salt and 0.8-1.5 parts of an inorganic auxiliary agent. According to the environment-friendly chemical polishing solution, the citric acid class polishing solution serves as the substrate material of the polishing solution, and the environment friendliness of the polishing solution is increased as citric acid is non-poisonous and free of pollution. In addition, the polyethylene glycol, the sodium dodecyl benzene sulfonate and the trisodium phosphate are added in the formula to carry out physical modification on the polishing solution, and the polyethylene glycol carries out viscosity adjustment and solubilization on the chemical polishing solution. The added trisodium phosphate can improve the wetting ability of water, surface dirt is removed, and the functions of dirt removal and polishing are realized.
