Scale from the press hardened metal element are removed by placing the press hardened metal element in an ultrasonic liquid and preforming an ultrasonic process thereon so as to obtain a de-scaled press hardened metal element. The ultrasonic liquid is an aqueous solution comprising an organic carboxylic acid in a concentration of from 0.1 to 10 vol.-%. The de-scaled press hardened metal element is coated in a coating process with an anti-corrosion coating.
