To remove rust from metal tools, you can use a few different methods. One common method is to soak the tools in a solution of equal parts white vinegar and water for a few hours, then scrub the rust off with a wire brush or steel wool. Another option is to create a paste using baking soda and water, apply it to the rusted areas, let it sit for a few hours, then scrub it off. You can also use a commercial rust remover product following the manufacturer's instructions. After removing the rust, make sure to dry the tools thoroughly and apply a thin coat of oil to prevent future rusting. **
