PROBLEM TO BE SOLVED: To provide a cleaning tool for removing dusts accumulated in corners, angles, and narrow gaps more appropriate than conventionally supplied scourers or brushes in terms of shape, strength, and size without causing damages by scraping away fixed dusts and damaging the material of a metal brush. SOLUTION: The tip of a brush with a number of roots implanted in a number of holes is shaped in a form with two acuminate peaks and a stick-shaped holding tool is fixed on the trestle of the brush for removing dusts accumulated in corners and gaps.
