What action helps prevent rust after cleaning tools?

• A. Lightly coat with oil spray
• B. Leave them wet
• C. Wipe with water only
• D. Sand them

Answer: (A)

After cleaning tools, the goal is to keep moisture away and block oxygen from reaching the metal. A light coat of oil spray creates a thin, protective film that repels water and slows the rusting chemical reaction. This simple barrier helps tools stay rust-free during storage or between tasks. Leaving them wet invites moisture to sit on the surface and promotes oxidation. Wiping with water only leaves dampness that can start rust. Sanding isn’t a rust-prevention step; it can remove protective coatings and create micro-scratches that trap moisture. So applying a light oil coating is the best practice.
