Simple Green is a popular all-purpose cleaner, but its effectiveness as an engine degreaser is a frequent question among car enthusiasts and DIY mechanics. This comprehensive guide explores Simple Green's capabilities for engine cleaning, weighing its pros and cons, and providing best practices for safe and effective use.
Is Simple Green Safe for Engine Cleaning?
This is the crucial first question. While Simple Green is marketed as a bio-degradable and relatively non-toxic cleaner, its suitability for engine cleaning requires careful consideration. The answer is a qualified yes, but with important caveats. Simple Green is generally less harsh than many dedicated engine degreasers, making it a potentially safer option for certain applications. However, it's crucial to understand its limitations and follow safety precautions.
Potential Issues:
- Sensitivity of Engine Components: Some engine components, particularly sensors and electrical parts, are sensitive to harsh chemicals. While Simple Green is less harsh than some alternatives, prolonged exposure or improper application can still cause damage.
- Incomplete Cleaning: Simple Green might not be as effective as dedicated engine degreasers for extremely stubborn grease and grime, especially in heavily soiled engines. This could require more scrubbing and potentially more applications.
- Environmental Concerns: While biodegradable, improper disposal of Simple Green or its runoff can still negatively impact the environment. Always dispose of used cleaner responsibly according to local regulations.
How to Use Simple Green for Engine Cleaning: A Step-by-Step Guide
This process requires careful preparation and execution to minimize risks and maximize results.
1. Preparation is Key:
- Protect Sensitive Areas: Cover sensitive electrical components, sensors, and the alternator with plastic sheeting or bags secured with tape.
- Cool Down the Engine: Ensure the engine is completely cool before starting the cleaning process. A hot engine can accelerate the evaporation of the cleaner and potentially create safety hazards.
- Gather Supplies: You'll need Simple Green, a garden sprayer or pressure washer (low pressure is recommended), brushes (various sizes for different areas), rags, and possibly engine degreasing wipes for spot cleaning.
- Work in a Well-Ventilated Area: Always work in a well-ventilated area or outdoors. Wear appropriate personal protective equipment (PPE), including gloves and eye protection.
2. Application and Cleaning:
- Dilute Simple Green: The recommended dilution ratio is usually found on the product label. Generally, a dilution of 1:10 (Simple Green to water) is a good starting point for engine cleaning. Adjust the dilution depending on the level of grime.
- Apply Evenly: Use a garden sprayer to apply the diluted Simple Green evenly across the engine compartment, focusing on heavily soiled areas. Avoid spraying directly onto sensitive components.
- Allow Soaking Time: Allow the solution to soak for 10-15 minutes. This allows the cleaner to break down the grease and grime.
- Scrub and Rinse: Use brushes to scrub away stubborn dirt. Start with softer brushes for delicate areas and move to stiffer brushes for more stubborn grime. Thoroughly rinse the engine with water, using a low-pressure setting if using a pressure washer.
3. Post-Cleaning:
- Dry Thoroughly: Use clean rags to dry the engine as much as possible. Pay close attention to electrical components to ensure they are completely dry to prevent short circuits.
- Inspect for Remaining Grime: Check carefully for any remaining dirt or grime. Re-apply Simple Green as needed, followed by thorough rinsing and drying.
- Dispose of Waste Properly: Dispose of used cleaning solution and rags according to local regulations.
Simple Green vs. Dedicated Engine Degreasers
While Simple Green offers a gentler approach, dedicated engine degreasers are usually formulated for superior cleaning power and are designed to handle tougher grime. The choice depends on the level of soiling and the desired level of cleaning intensity. For lightly soiled engines, Simple Green can be a viable option; for heavily soiled engines, a dedicated degreaser might be necessary.
Conclusion
Simple Green can be used for engine cleaning, but it's crucial to understand its limitations and safety precautions. This guide outlines a safe and effective process for using Simple Green to clean your engine, but always prioritize safety and responsible waste disposal. Remember to always check the Simple Green product label for the most up-to-date dilution recommendations and safety information. If you are unsure, it’s always best to consult a professional detailer or mechanic.
