Depending on the amount of rust/patina you are dealing with wet the rust eraser with water and using light pressure rub it back and forth over the affected area. For heavier rust, you may need to start with the medium and then change to the fine as you are getting close to finishing. Always rinse the kitchen knife or tool under very hot water and as it is prone to rust apply a fine coating of Camellia Oil.
