One method is to connect the body to the Earth using a conducting wire, known as grounding. This allows the excess charge to flow from the body to the Earth, neutralizing the charge. Another method is to place the body in contact with an opposite charged object, causing the charges to neutralize each other.
A charged insulator can be neutralized by grounding it, which involves connecting it to the Earth's surface with a conductor. This allows the excess charges to flow away, leaving the insulator with zero net charge. Alternatively, you can also neutralize a charged insulator by introducing an opposite charge to cancel out the excess charges.
