Simple Green is a popular, multi-purpose cleaner, but its use on car paint is a subject of ongoing debate among car enthusiasts. This comprehensive guide will explore the pros and cons, offering a balanced perspective and practical advice to help you determine if Simple Green is right for your vehicle.
Understanding Simple Green's Composition
Simple Green is a biodegradable cleaner boasting a powerful, yet supposedly gentle, cleaning formula. Its exact composition is proprietary, but it generally includes surfactants, solvents, and other cleaning agents. While marketed as safe for various surfaces, its impact on car paint requires careful consideration.
Simple Green: Potential Benefits and Risks
Potential Benefits:
-
Effective Cleaning: Simple Green excels at removing stubborn grime, bugs, and light road film. Its degreasing properties can be beneficial for cleaning wheels, tires, and engine bays. For less delicate areas, it can be a viable cleaning option.
-
Biodegradability: Its biodegradable nature aligns with environmentally conscious practices, making it a potentially "greener" alternative to harsher chemical cleaners.
Potential Risks:
-
Paint Damage: The concern with using Simple Green on car paint revolves around the potential for stripping wax and damaging clear coat. While diluted solutions might seem harmless, prolonged exposure or improper use can lead to dullness, etching, or even paint discoloration. The chemicals can also potentially strip protective coatings.
-
Unknown Long-Term Effects: The long-term effects of repeated Simple Green applications on various paint finishes remain relatively unknown. While marketed as safe, lack of comprehensive, long-term studies raises potential concerns.
-
Incompatible with Certain Finishes: Certain car paint types and coatings may react negatively to the chemicals in Simple Green. Always test the product on an inconspicuous area before widespread application.
Safe Use of Simple Green on Your Car (If You Choose to Use It)
Proceed with extreme caution and only if absolutely necessary. If you do decide to use Simple Green on your car, follow these steps:
-
Dilution is Key: Always dilute Simple Green significantly more than suggested for general cleaning purposes. A ratio of 1:10 (1 part Simple Green to 10 parts water) or even weaker is recommended.
-
Test in an Inconspicuous Area: Before applying to the entire vehicle, test the diluted solution on a small, hidden area (like the underside of the hood or a panel in the wheel well). Observe the area for several hours to check for any adverse reactions like dulling or discoloration.
-
Quick Application and Rinse: Apply the solution quickly using a microfiber wash mitt or sponge, then immediately rinse thoroughly with clean water. Do not let the solution dwell on the paint for extended periods.
-
Avoid Direct Sunlight: Never apply Simple Green in direct sunlight, as it can cause the solution to dry too quickly and potentially damage the paint.
-
Use a pH-Neutral Soap Afterwards: After rinsing, wash the car again with a pH-neutral car wash soap to remove any remaining Simple Green residue and restore the protective layer.
-
Wax/Sealant Application: After washing, apply a good quality wax or sealant to replenish your car's protective layer.
Alternatives to Simple Green for Car Cleaning
For cleaning your car, consider these safer, more car-paint-friendly alternatives:
-
Dedicated Car Wash Soaps: These are specifically formulated for automotive paint and are less likely to cause damage.
-
Bug and Tar Removers: These specialized products tackle stubborn contaminants without the potential risks associated with Simple Green.
-
Wheel Cleaners: Use cleaners specifically designed for wheels and tires.
Conclusion: Proceed with Caution
Simple Green can clean certain parts of your car effectively, but its use on the car's paint should be approached cautiously. Due to the potential risks of paint damage and the lack of definitive long-term studies, using a dedicated car wash soap is always the safer and recommended approach. Remember, preventative maintenance, including regular washing and waxing, is crucial for preserving your car's paint finish. Always prioritize the health and longevity of your vehicle's paint.
