The invention relates to a method and device for descaling and/or cleaning a metal casting ( 1 ), particularly a hot-rolls trip made of normal steel or of stainless steel. According to the inventive method, the metal casting (1) is guided in a direction of conveyance (R) through a device ( 2 ), inside of which it is subjected to a plasma descaling and/or a plasma cleaning. In order to improve the result of the descaling or of the cleaning of the metal casting, the invention provides that before the device ( 2 ) for plasma descaling and/or plasma cleaning, in the direction of conveyance (R), the metal casting ( 1 ) is subjected to a process that imparts a high degree of flatness to the metal casting ( 1 ).
