The cleaning-fin (F) comprises at least a spatulate apical portion (3), a pair of bottom portions (4,5) fixed in the head (7) having therebetween an interval, and a pair of side walls (1,2) connecting the spatulate apical portion (3) and each of the bottom portions (4,5). The pair of side walls (1,2) form therebetween a hollow triangle (13) becoming narrower toward the spatulate apical portion (3).
