The invention discloses an electronic cleaning brush for an electronic circuit board. The electronic cleaning brush comprises a device main body and cleaning rods, wherein four cleaning rods are arranged at the bottom end of the device main body; tops of the cleaning rods are all fixedly connected with the device main body; a right rotating cylinder is arranged at the left end of the outer surfaceof the device main body; the right rotating cylinder is arranged in the device main body in an embedded manner. Meanwhile, a method that cleaning is made by using brush hair of a conventional devicehas the problems that as the brush hair is small and long and has certain hardness, metallic element pins on the surface of a circuit board can be damaged when cleaning is made at certain pressure, then later connection faults can be caused, and the cleaning efficiency is low, so that the electronic cleaning brush is provided with a sponge brush, the sponge brush is made of a sponge material whichis arranged at the bottom of the cleaning rods in a sleeving manner, the surface of the circuit board can contact the soft sponge firstly in cleaning, rapid rotational cleaning can be made at certainpressure, and sponge inside can be tightly adhered to the surface of the circuit board.
