A device for cleaning the surface of a tool for the forming of the surface of a large-area fiber composite material body using a highly-pressurized cleaning liquid, comprising - a nozzle support rotatably mounted on a central bearing , - at least one jet nozzle held in an arm of the nozzle support , from which the highly-pressurized cleaning liquid exits during operation, - a control unit for controlling the pressure of the cleaning liquid to be applied, - wherein the nozzle support is enclosed by a housing , which is provided with an opening toward the surface to be cleaned of the tool , - wherein the housing is attached to a suction unit, using which an interior of the housing , in which the nozzle support is arranged, can be suctioned off, - wherein the interior of the housing is connected via a pressure valve to an external environment, - wherein a shape-flexible liquid-tight seal is arranged at the end of the housing forming the opening , using which seal the space between the nozzle support and the surface to be cleaned of the body can be sealed off from the external environment, - wherein the housing has a double-walled lateral surface, having an intermediate chamber formed between an outer wall and an inner wall , wherein a shape-flexible seal is arranged in each case on the outer wall and the inner wall , characterized in that - the control unit has at least two pressure range settings, wherein in a first pressure range setting, the pressure of the cleaning liquid exiting from the at least one jet nozzle is set in such a way that fiber composite material residues are removable from a surface of the tool coated using a release agent without damaging the release agent and, in a second pressure range setting, the pressure of the cleaning liquid exiting from the at least one jet nozzle is set in such a way that the release agent is removable from the surface of the tool using the at least one jet nozzle - wherein the outer wall and/or the inner wall is designed as rotatable about an axis of rotation (Dz) of the nozzle support . - a nozzle support rotatably mounted on a central bearing , - at least one jet nozzle held in an arm of the nozzle support , from which the highly-pressurized cleaning liquid exits during operation, - a control unit for controlling the pressure of the cleaning liquid to be applied, - wherein the nozzle support is enclosed by a housing , which is provided with an opening toward the surface to be cleaned of the tool , - wherein the housing is attached to a suction unit, using which an interior of the housing , in which the nozzle support is arranged, can be suctioned off, - wherein the interior of the housing is connected via a pressure valve to an external environment, - wherein a shape-flexible liquid-tight seal is arranged at the end of the housing forming the opening , using which seal the space between the nozzle support and the surface to be cleaned of the body can be sealed off from the external environment, - wherein the housing has a double-walled lateral surface, having an intermediate chamber formed between an outer wall and an inner wall , wherein a shape-flexible seal is arranged in each case on the outer wall and the inner wall , - the control unit has at least two pressure range settings, wherein in a first pressure range setting, the pressure of the cleaning liquid exiting from the at least one jet nozzle is set in such a way that fiber composite material residues are removable from a surface of the tool coated using a release agent without damaging the release agent and, in a second pressure range setting, the pressure of the cleaning liquid exiting from the at least one jet nozzle is set in such a way that the release agent is removable from the surface of the tool using the at least one jet nozzle - wherein the outer wall and/or the inner wall is designed as rotatable about an axis of rotation (Dz) of the nozzle support . <EOS>
