The balancing brushes are made of plastic material, which is injection moulded, in one single piece finished and ready for application of bristles, in particular equipped with perfectly smooth, cylindrical pins, that is without presence of burrs. The attachment to the supports consists of, on the brushes, a pin at each extremity, with diameter slightly less that the seat, substantially semi-cylindrical, under the support and slightly above the opening leading to the substantially semi-cylindrical seat. The bristles, vertically considered, are distributed in six columns which, in alternate lines are, with respect to four quiffs of bristles and two quiffs of bristles, where the six central quiffs of each tern of lines of quiffs result in being positioned as the corners of a regular hexagon. In the brush used for wet operation, the six central quiffs of each tern of lines of quiffs, result in being positioned as the corners of a regular hexagon, which centre determines the position of the passage holes, for the feeding of soapy water.
