What method is generally acceptable for inspecting a stainless steel control cable?

For inspecting a stainless steel control cable, running a cloth over it is a generally acceptable method. This technique allows for the identification of any noticeable abnormalities on the surface of the cable such as nicks, cuts, or corrosion. The friction created by the cloth can also help to reveal imperfections that are not easily visible during a standard visual inspection.

Using a magnet, while helpful in identifying ferromagnetic materials, is not effective for stainless steel, as many grades of stainless steel are non-magnetic, making it an inappropriate choice for inspection. Visual inspection can be useful but may miss defects that are more easily detected through tactile means. Applying lubricant is not an inspection method but rather a maintenance procedure and doesn't provide information on the integrity of the cable itself.
