Cleaning oil from under the hood involves removing accumulated grime and grease to improve engine appearance and potentially identify leaks more easily. Here's a step-by-step guide for manual cleaning:
Steps for Cleaning Oil Under the Hood:
-
Preparation:
- Safety First: Disconnect the negative terminal of your car battery. This prevents accidental electrical shorts during cleaning. Wear safety glasses and gloves.
- Gather Supplies: You'll need:
- Oil Eater® All Purpose Cleaner (or similar degreaser)
- Non-metallic brush (a parts cleaning brush or a soft-bristled brush will work)
- Hose with a spray nozzle
- Clean rags or towels
- Plastic bags or covers to protect sensitive electrical components (alternator, distributor, etc.)
-
Protection:
- Cover any exposed electrical components like the alternator, distributor, air intake, and any open wiring with plastic bags or covers to prevent water damage.
-
Application:
- Spray Oil Eater® All Purpose Cleaner (or your chosen degreaser) liberally over the entire engine bay, focusing on areas with heavy oil buildup.
-
Soaking:
- Allow the degreaser to soak for approximately five minutes. This allows the cleaner to penetrate and loosen the greasy buildup.
-
Scrubbing:
- Use a non-metallic brush to scrub the engine bay, paying attention to areas with stubborn grease and grime. Avoid using harsh brushes that could damage plastic or rubber components.
-
Rinsing:
- Thoroughly rinse the entire engine bay with a hose and spray nozzle. Ensure all traces of the degreaser are removed. Avoid spraying directly into sensitive electrical components, even if covered.
-
Drying:
- Remove the plastic bags or covers.
- Use clean rags or towels to dry the engine bay as much as possible. You can also let the engine air dry.
-
Reconnection:
- Reconnect the negative terminal of your car battery.
-
Inspection:
- Start the engine and let it run for a few minutes. Check for any leaks or unusual noises.
Important Considerations:
- Engine Temperature: Ensure the engine is cool before starting the cleaning process.
- Environmental Responsibility: Be mindful of where the oily runoff goes. Avoid letting it enter storm drains. Consider using a degreaser that is biodegradable.
- Alternative Cleaning Methods: Pressure washing can be used, but it's generally not recommended for inexperienced users, as it can damage sensitive components if not done carefully.
- Professional Detailing: If you're uncomfortable cleaning the engine bay yourself, consider hiring a professional auto detailer.
By following these steps, you can effectively clean oil from under the hood and improve the overall appearance and maintenance of your engine.
