Magnetic cleaning system and method for cleaning ferromagnetic objects

A method for cleaning a surface of a ferromagnetic object, the method comprising:

• selecting a cleaning system that includes a device body comprising a magnetic system configured to generate a magnetic field, the device body coupled to an abrasive layer configured for selective placement against the surface;
• placing the abrasive layer in contact with the surface with the magnetic field generated by the magnetic system urging the abrasive layer against the surface of the ferromagnetic object with a magnetic force corresponding to a strength of the magnetic field;
• and
• moving the abrasive layer relative to the surface while the abrasive layer is in contact with the surface.
