WHEN USED –

This is Step #1 when replacing your motor brushes, and first aid when your armature is turning black. Those black markings (carbon build up) on the commutator act as an insulator and can cause increased amp draw (and you certainly don’t need that). By getting that clean copper color back you assure a true brush-to-surface contact (and you certainly DO want that). Need help on how to use the cleaner? Give us a call… we’re here to help.
