Add scratches to a material in Cycles?

Question

Is there a way to add scratches (like on worn metal) to a shader in Cycles?

Mix a diffuse shader, to the rest of the node tree, based on a texture; It really depends on your material, though — someonewithpc, Dec 22 '14 at 21:57
Use a scratch texture in the normal of a diffuse shader, or the displacement of an output shader . . . — J Sargent, Dec 22 '14 at 22:03

The simplest way is to use a box-mapped scratch texture to control the roughness of a glossy shader:
