PURPOSE:To obtain an abradant useful for abrading barrels, etc., having excellent abrading action, rapidly and readily cleanable without using trichlene, etc., after abrading treatment by blending an abrading material with a surfactant and a de-fatting agent in a specific ratio. CONSTITUTION:This abradant is obtained by mixing 100 pts.wt. of an abrading material (e.g. sand stone, corundum, synthetic tire or alumina) with 0.1-10 pts.wt. of at least one of a surfactant and a de-fatting agent and preferably contains further a fibrous component (e.g. wood fiber, wool, glass fiber, rayon, preferably vegetable fiber composed of paper). |
