Abstract: The present invention relates to a method for producing an insulation tube (1) for an electrode for medical applications, preferably for implantation as part of a functional electrostimulation device and a method for producing such an electrode. The insulation tube (1) has a first, essentially hollow cylindrical layer (11) and at least one second layer (12), which is arranged on the lateral surface (15) of the first layer (11) and covers it at least partially. The invention is characterized in that the lateral surface (15) of the first layer (11) is cleaned in a cleaning step by means of a first liquid cleaning agent at a temperature below 30° C., preferably below 20° C., before applying the at least one second layer (12).
