Examples I have seen on youtube are for cleaning the brake dust of wheels, but I think it should do the same job on calipers aswell. The idea is you spray it on and leave it to soak for a few minutes, after which time it changes color (usual pink or purple). Then you simply rinse it off with water and for more stubborn instances, agitating with an toothbrush rinse and repeat if as required.
It works but in my experience no better than WW when used correctly.
