After cleaning, what is the proper anti-rust procedure for metal tools?

The proper anti-rust procedure for metal tools after cleaning involves thoroughly drying them. When metal tools are cleaned, they can retain moisture, which can accelerate rust formation. By drying them thoroughly, you remove any remaining moisture from the surface, thereby minimizing the risk of corrosion. This step is crucial because even small amounts of water can lead to rusting over time.

Applying oil immediately, while it can be a good follow-up step, should be done after ensuring that the tools are completely dry. This ensures that the oil can form a protective barrier on a clean, dry surface rather than trapping moisture, which would defeat the purpose of rust prevention. Therefore, drying thoroughly is vital in the maintenance of metal tools to ensure long-term usability and protection against rust.
