The most preferred abrasives are silica for softer metals, and a combination of silica and garnet for harder metals. The preferred detergents are oil based sulfonates, and more preferably sodium dodecylbenzenesulfonate. The preferred carrier is selected from the group consisting of barium sulfate and the barium soaps of fatty acids, the barium soaps having a solubility factor in water of not more than 0.008 grams per cubic centimeter of water, and further being generally insoluble in acid.
