Which solvent is used to clean an old bearing?

• A. Solvent
• B. Kerosine
• C. Alcohol
• D. A light oil

Answer: (A)

Cleaning an old bearing relies on dissolving and washing away the old grease and grime from the bearing surfaces. A solvent is the substance whose job is to dissolve oils and dirt so you can flush them away and leave the parts clean for inspection and re-lubrication. That broader term fits best because it describes the action you need—the cleaning power to dissolve contaminants—rather than naming a specific chemical. For example, kerosene can be used as a solvent, alcohol can work for some residues, and a light oil is a lubricant, not a cleaner. So the general solvent option captures the method you’d use to properly clean the bearing.
