The invention relates to the technical field of the cleaning agent, in particular to a modified hydrocarbon cleaning agent. The main technical scheme in the invention is as follows: additives are added in the hydrocarbon cleaning agent which contains solvent without aromatic hydrocarbons, solvent with low aromatic hydrocarbons and C10-13 normal paraffin or isoparaffin, namely alcohol additive, ester additive and ether additive are added in the hydrocarbon cleaning agent D40, D60, D65 and D80 and the hydrocarbon cleaning agent C10, C11, C12 and C13 to ensure that the modified hydrocarbon cleaning agent has high cleaning capability, high KB value, low aniline point, low cost, little odor and high recovery rate, can be used to clean macromolecular pollutants such as wax, resin, printing ink and rosin and can be heated for cleaning in a special device.
