Composition for producing a lubricant composition

A composition obtainable by combining a component (A) and at least two metal salts (M) and water, component (A) consisting of one or more inorganic salts selected from sulfite, disulfite, thiosulfate, phosphate, polyphosphate, pyrophosphate, metaphosphate or salts or mixtures thereof, wherein the metal salts (M) differ in the oxidation number of the metal and the metal is Fe, wherein the concentration of component (A) is in the range from 5% to 20% by weight based on the total weight of the lubricant composition, and the total concentration of the metal salts (M) is in the range from 5% to 10% by weight based on the total weight of the lubricant composition, wherein the composition is a lubricant solution and has a pH of 9 to 10.
