A brush is made by twisting a plurality of core elements (1, 1) and tightly holding elongated cloth pieces (3) in gaps between the twisted core elements. When the elongated cloth pieces are made from a fabric woven with ultra-fine fibers to make loops, or from a moquette fabric of ultra-fine fibers whose tips are raised, the brush can be used either as a washing tool or as a pinting tool which is adaptive to surfaces of all types of articles, including hard articles and delicate and soft articles, and performs an excellent washing or painting effect.
