You can use Simple Green to wash your car, but it’s essential to do so carefully. This cleaner effectively removes dirt and grime, especially from tires and wheels. However, be cautious; improper use can harm your car’s paint and finish. Diluting it properly is key to safe and effective cleaning.
Key Takeaways
Dilute Simple Green properly to protect your car’s finish. A mixture of one part Simple Green to ten parts water is recommended for safe cleaning.
Test Simple Green on a small area before applying it to larger surfaces. This helps ensure it won’t damage sensitive materials like rubber or leather.
Consider eco-friendly alternatives for car washing. Products like Dr. Bronner’s Liquid Castile Soap and Meguiar’s Gold Class Car Wash are effective and gentle on the environment.
Effectiveness of Simple Green

Cleaning Power
When you use Simple Green, you’ll find it does a great job of tackling dirt and grime on your car. This all-purpose cleaner effectively removes common contaminants like dust, dirt, and even bird droppings. In fact, a quick look at its performance reveals that it rates high for cleaning dirt and dust, while it shows moderate effectiveness against tree sap and bird droppings. Here’s a quick breakdown:
Contaminant | Effectiveness |
|---|---|
Dirt | High |
Dust | High |
Tree Sap | Moderate |
Bird Droppings | Moderate |
However, while Simple Green shines in many areas, it does have its limitations. It may not be as effective as specialized automotive cleaning products, especially when it comes to tough stains or specific contaminants. For instance, dedicated wheel cleaners are designed to break down brake dust more effectively than Simple Green. If you’re dealing with heavy road film or large dirt particles, you might want to consider using products specifically formulated for automotive cleaning.
Comparison with Other Products
Simple Green is known for its clean-rinsing, streak-free formula. This means it won’t dull your car’s waxed surfaces, which is a significant advantage over some other products. For example, Karcher’s Vehicle Wash and Wax Detergent can leave a dull finish unless you hand-dry the car, leading to more streaking and residue.
That said, automotive professionals often express concerns about using Simple Green. They warn that it might not be as effective as other cleaning products and could potentially cause damage to car fabrics. Some users have reported that it’s too strong for interior surfaces, preferring milder products designed specifically for automotive interiors.
Use Simple Green Safely

Impact on Wax and Finish
When you wash your car with Simple Green, you need to be aware of how it can affect your car’s wax and finish. While Simple Green is effective at cleaning, it can strip away wax if used improperly. This means your car may lose its shine and protection. To avoid this, always dilute the cleaner according to the instructions. A good rule of thumb is to use a mixture of one part Simple Green to ten parts water for general cleaning. This dilution helps maintain your car’s protective layer while still getting rid of dirt and grime.
Compatibility with Materials
You should also consider the materials your car is made of when using Simple Green. Some components, like rubber and leather, can be sensitive to harsh cleaners. Users have reported that Simple Green can dry out rubber and leather surfaces, leading to cracks and deterioration. For example, one user mentioned they wouldn’t use it straight on leather because it could dry it out significantly unless diluted.
Here are some materials and their compatibility with Simple Green:
Aluminum: Some Simple Green products may attack aluminum unless the correct formulation is used. It’s crucial to rinse well after using Simple Green on aluminum to prevent corrosion.
Rubber: Simple Green can dry out rubber components, so be cautious when using it on seals or tires.
Plastic: Generally safe, but always check the specific product guidelines to ensure compatibility.
To keep your car looking its best, always rinse thoroughly after using Simple Green. This step is especially important for aluminum surfaces, where residue can lead to corrosion over time.
Tip: Always test a small, inconspicuous area before applying Simple Green to larger surfaces. This way, you can ensure it won’t cause any damage.
By following these guidelines, you can safely use Simple Green to wash your car without compromising its finish or damaging sensitive materials.
Proper Dilution and Application
Recommended Ratios
To get the best results when you use Simple Green, proper dilution is crucial. Here are some recommended ratios to consider:
1:1 Ratio: Some users suggest mixing one part Simple Green with one part water. However, this can dull your car’s finish.
5:1 to 10:1 Ratio: For manual cleaning, a dilution of five parts water to one part Simple Green is effective. You can go up to ten parts water for lighter cleaning tasks.
Finding the right balance is essential. Higher concentrations can improve cleaning power but may also risk damaging sensitive materials like aluminum. So, always err on the side of caution!
Application Steps
Follow these steps for a safe and effective wash:
Prepare Your Car: Cover sensitive areas like the dashboard and seats with water-resistant drops.
Wet the Jambs: Start by wetting the jambs from the bottom of the pillar around to the lock latch.
Apply Simple Green: Liberally apply the diluted cleaner to the surfaces you want to clean.
Scrub: Use a mitt for painted surfaces and a toothbrush for hinges and seals. Rinse thoroughly.
Repeat: Go through the jambs again to ensure a thorough clean.
Dry: Use compressed air to dry hard-to-reach areas and prevent water spots.
Tip: Always rinse well to avoid residue that can lead to corrosion or damage.
By following these steps, you can effectively use Simple Green to wash your car while keeping it safe from potential harm.
