Abstract
Prior art methods for removing a layer area of a component (stripping) lead to poor results since a removal, for example, ensues in a nonuniform manner. In addition, these prior art methods are time intensive. An inventive method for removing a layer area of a component consists of firstly treating the layer areas to be removed with a salt solution and then with acid, whereby in an intermediate or final step, the component is treated with a complexing agent.
