The invention relates to a device for cleaning the surface of a tool for shaping the surface of a large-area fiber composite material body using a highly pressurized cleaning liquid, having a nozzle support which is held on a central bearing in a rotatable manner, at least one jet nozzle which is held in an arm of the nozzle support and out of which the highly pressurized cleaning liquid exits during operation, and a control unit for controlling the cleaning liquid pressure to be applied, wherein the nozzle support is surrounded by a housing which is provided with an opening towards the tool surface to be cleaned. The housing is connected to a suction device by means of which a housing interior equipped with the nozzle support can be suctioned. The housing interior is connected to an outer surrounding area via a pressure valve, and a liquid-tight seal with a flexible shape is arranged on a housing end which forms the opening, wherein the seal can be used to seal the space between the nozzle support and the body surface to be cleaned from the outer surrounding area, and the control unit has at least two pressure range settings. The invention additionally relates to a method for cleaning a surface of a tool.
