Multiple Choice

The contacts on a magnetic starter should be cleaned with a ___.

Cleaning electrical contacts requires removing oxide and corrosion from the metal surfaces without creating deep scratches or leaving abrasive particles behind. Crocus cloth is a very fine abrasive cloth designed for this purpose, so it effectively cleans and smooths the contact surface without leaving grit or damaging the metal. Sandpaper and emery cloth are too coarse and can scratch or deposit particles that cause future arcing or contamination, while a brush can leave fibers or metal fragments. After cleaning, wipe away any loosened debris and inspect the contacts.
