The invention discloses electrolytic polishing solution for detection pretreatment of a magnesium alloy texture. The used electrolytic polishing solution is 20 to 40 percent natal, preferably 35 percent nital. The electrolytic polishing solution can further improve the flatness and the finish of the surface of the magnesium alloy, effectively eliminate a stress layer introduced into the surface of the magnesium alloy during preliminary sample preparation, and improve the calibration rate of the texture; meanwhile, by using the electrolytic polishing solution, the polishing process is simple to operate and the polishing effect is stable, and compared with the conventional products, the electrolytic polishing solution has the advantages of wide raw material source, simplicity in preparationand low cost; and the invention also discloses an electrolytic polishing process for the detection pretreatment of the magnesium alloy texture, which is simple in operation, high in treatment speed and stable in effect.
