Soft99 Rust Eraser
It is much easier to use than the abrasive sandpaper and allows you to remove rust from any part without damaging the other parts.
If you sharpen its edge with a cutter, it is possible to get rid of rust from gaps or corners easily.
You can choose to use a hard surface or a soft surface.
Directions to use
* When rubbing the rust, use the hard or soft side as needed.
* Cut the eraser as needed to rub narrow spaces or corners.
