What is the best method to remove a slight coating of rust from small tools?

Rubbing with kerosene and fine steel wool is an effective method for removing a slight coating of rust from small tools. Kerosene acts as a lubricant and solvent, which helps to loosen rust while also protecting the metal surface from scratches. The fine steel wool is gentle enough to clean the surface without causing significant damage to the underlying material. This combination efficiently removes rust while minimizing the risk of further corrosion or harming the tool.

In contrast, while a vinegar solution can also be effective for rust removal, it may not always provide the same level of surface protection as kerosene. Sanding with coarse grit paper could remove rust but runs the risk of damaging the tool's surface or leaving scratches, which could hinder its performance. Applying water and soap is not effective for rust removal, as soap and water do not address the rust directly and may even accelerate rust formation if the tool is not dried properly afterward.
