Abstract

A liquid rust removal composition including a mixture of an organic acid and an inorganic acid present in an effective amount to remove and/or prevent rust on a substrate post-application; a surfactant present in an effective amount to form a coating and/or adhere to the substrate post-application; a corrosion inhibitor dispersed within the liquid composition; and water at a concentration of up to 80 wt % of the liquid composition. Also, a gelatinous rust removal composition including a chlorinated acid present in an effective amount to remove and/or prevent rust on a substrate post-application; a surfactant present in an effective amount to form a coating and/or adhere to the substrate post-application; a corrosion inhibitor dispersed within the gelatinous composition; and water at a concentration of up to 40 wt % of the gelatinous composition.
