A device for cleaning channels including a rod-shaped carrier element, at least one cleaning element that is connected with the carrier element, and at least one additional cleaning element that can be detached from the carrier element. A method for cleaning instrument channels wherein the cleaning device is moved in the axial direction in the instrument channel as far as an end point； after reaching the end point the cleaning device is moved back in the opposite axial direction in the instrument channel. Owing to the reverse motion of the cleaning device, the detachable cleaning element is released from the carrier element and thereafter is no longer part of the cleaning process of the previously cleaned instrument channel and can no longer soil the channel. The device and method removes from the instrument channel the substances that are to be removed and produces an efficient and good cleaning result.
