Abstract: A composition for removing metal oxides from stainless steel is disclosed. The composition is an aqueous solution of nitric acid, sulfamic acid and a chelating agent selected from a group comprising amino acids and hydroxy acids. The solution should be applied at an elevated temperature.
Abstract: Composition and method for removing metal oxides from ferrous metals. The composition contains an ammonia derivative such as an amine, a strong mineral acid and an organic chelating agent for the metal oxides in an aqueous solution having an acidic pH of about 0.5-3.0. Metal oxides are most readily removed by applying the solution at elevated temperature.
Abstract: Composition and method for removing metal oxides from ferrous metals. The composition contains an ammonia derivative such as an amine, a strong mineral acid and citric acid in an aqueous solution having an acidic pH of about 0.5-3.0. Metal oxides are removed by applying the solution at elevated temperature.
Abstract: Small, effective fire igniter tablets are provided comprising a major amount of a combination of wax and a cellulosic material powder in the form of a tablet or cylinder and a minor amount on and/or near the surface of said tablet or cylinder of an aliphatic diacyl peroxide. The tablets are found to readily ignite and burn for a sufficient time to insure kindling of logs or other solid fuel, both natural and synthetic.
