What advice would you give someone trying to loosen a rusty nut with a wrench?

Loosening a rusty nut can require careful handling to avoid stripping the nut or damaging the surrounding area. Moving your hand further from the nut can provide better leverage and allow for a more controlled and efficient application of force. When your hand is positioned farther away, you can use your arm and body weight more effectively to apply torque, which can help break the rust's grip on the nut.

Additionally, techniques that involve applying heat can expand the metal and may also assist in loosening the nut, but physical leverage and increasing torquing ability are often more immediately effective. Therefore, the strategy of adjusting your grip to enhance leverage is a practical approach when dealing with stubborn, rusted components.
