A method of making a sacrificial coating composition is disclosed. The method comprises emulsifying an oil with surfactant and water to form an oil-in-water emulsion; and combining ingredients comprising (i) at least one polymer, (ii) at least one hygroscopic material, (iii) the oil-in water emulsion and (iv) water to produce the sacrificial coating composition. The at least one polymer is selected from the group consisting of a hydrophilic polymer, a latex comprising polymer particles dispersed in a continuous liquid phase, or mixtures thereof.
