adding alkaline salt and inorganic salt into a cleaning liquid system, wherein the weight ratio of the inorganic salt is 1:(1-1.5) sodium chloride and sodium hypophosphite, not only the removal effect of oil stains is excellent, but also the problem of generally poor stability of the semi-aqueous base system is unexpectedly alleviated; the density is 0.72-0.79g/cm 3 The distillation range is 12-25 ℃; the hydrocarbon solvent with the initial boiling point of 100-180 ℃ and the final boiling point of 150-220 ℃ further enhances the cleaning effect, and simultaneously, the friction between the blade and the casing is obviously reduced after cleaning, so that the possibility of abrasion of the bearing of the aeroengine and the blade fracture is reduced.
