What is the correct recommended approach after cleaning regarding moving parts and lubrication?

• A. Immersed in solvent for several minutes
• B. Wipe dry, moving parts free of moisture, apply light lubrication
• C. Leave parts wet
• D. Add heavy oil to all surfaces

Answer: (B)

After cleaning, the moving parts should be wiped dry and given a light, even coating of lubricant. Keeping surfaces free of moisture prevents rust and corrosion, which can seize parts or create pitting in metal over time. Removing solvent residues is also important because they can, if left behind, degrade lubrication and attract dirt. A light lubrication provides enough film to reduce wear and friction during movement without creating a gummy buildup or attracting dust, which can happen if you use heavy oil on all surfaces. Immersing parts in solvent, leaving them wet, or applying heavy oil on everything can flush away lubrication, trap contaminants, or hinder operation, so they’re not recommended.
