Washing your car at home can save you money, and with the right tools, it can be a fun weekend project. If you’ve heard about Simple Green and wonder if it’s a good choice for cleaning your car, you’re in the right place! Simple Green is a versatile cleaner known for its ability to clean almost anything, but can it be trusted to wash your car? Let’s dive in and explore why Simple Green might just be your new best friend for car cleaning.

Is Simple Green Safe for Washing Cars?
When it comes to washing your car, using the right cleaning products is key. Many people are curious if they can use Simple Green for washing cars, and the good news is, yes, you can! But, like with anything, it’s important to use it correctly.
Simple Green is a powerful cleaner that works on a variety of surfaces. It’s designed to clean grease, grime, dirt, and stains. Because it’s a degreaser, it’s especially helpful when you’re dealing with tough oil and dirt build-up on your car’s wheels, tires, and engine bay. But, just because it works well doesn’t mean it’s always the best option for every car surface.
Simple Green is a non-toxic, biodegradable product, which makes it safer for both you and the environment. It’s a great alternative to harsher chemical cleaners that can be damaging to the car’s paint and finish. However, like with any product, there are a few things to keep in mind.
The first thing to know is that you should always dilute Simple Green before applying it to your car. Using it in a concentrated form could be too strong and might harm your car’s paint over time. To make sure it’s safe, you’ll want to mix it with water. Typically, a ratio of one part Simple Green to ten parts water is perfect for most car cleaning tasks.
If you’re planning on using it on your car’s paint, make sure to rinse it off quickly to avoid any possible long-term effects. For sensitive areas like windows, headlights, and mirrors, always use a light touch and test a small, hidden area first.
In short, Simple Green is generally safe for washing your car as long as you dilute it properly and take care with certain surfaces. Let’s explore how to properly use it in the next section!
How to Properly Use Simple Green to Clean Your Car
Now that we know Simple Green can be safe for washing your car, let’s go over how to use it the right way. Getting the best results means using the right approach and being mindful of the different parts of your car.
1. Gather the Supplies
Before you start, make sure you have everything you need for a successful car wash. Here’s a simple list to get you started:
- Simple Green cleaner
- A large bucket
- Water (preferably lukewarm)
- A microfiber wash mitt or sponge
- A hose with a nozzle for easy rinsing
- Towels or microfiber cloths for drying
- A wheel brush (optional)
- A tire brush (optional)
Once you have everything ready, it’s time to get to work!
2. Prepare the Simple Green Solution
Simple Green is a concentrated cleaner, so it’s essential to dilute it with water. The right dilution depends on what you’re cleaning, but for most car washing tasks, a mix of one part Simple Green to ten parts water should do the trick.
Start by filling your bucket with lukewarm water, then add Simple Green. Stir it gently to mix everything together. If you’re focusing on a particularly dirty area, like the wheels, you can make the solution stronger by adding a bit more Simple Green, but remember to dilute it for the rest of your car to avoid damaging the paint.
3. Rinse Your Car First
Before you start scrubbing, it’s a good idea to rinse your car with water. This helps remove loose dirt and debris, preventing scratches during the washing process. Using a hose, spray your car down thoroughly, starting from the top and working your way down. This will help to loosen the dirt and grime on the surface.
Make sure to rinse the wheels and tires too, as they tend to collect the most dirt and brake dust.
4. Wash Your Car with Simple Green
Once the car is wet, dip your wash mitt or sponge into the bucket with your diluted Simple Green solution. Start washing the car from the top down, using gentle circular motions. It’s important to keep the mitt or sponge clean by rinsing it regularly in the bucket. This prevents dirt from building up on the mitt and scratching the surface.
For stubborn spots like bird droppings or tree sap, you can apply a little more Simple Green directly to the spot and let it sit for a minute before scrubbing. Just be sure to wash the area thoroughly afterward to remove any residue.
When you get to the wheels and tires, you can use a separate brush to scrub the rims and tires. If they’re especially dirty, you might want to use a slightly stronger concentration of Simple Green in your bucket.
5. Rinse Thoroughly
After you’ve washed the entire car, it’s time to rinse everything off. Start from the top and work your way down again, making sure all the Simple Green solution is washed off. Leaving cleaner residue on the surface can lead to streaks or spots, so be thorough.
6. Dry Your Car
Once your car is rinsed, use a soft, clean towel or microfiber cloth to dry the surface. Drying your car helps prevent water spots from forming, especially in areas with hard water. Wipe the car in straight lines, starting at the top and moving down to ensure an even, spot-free finish.
7. Extra Tips for a Shiny Finish
To give your car a glossy, shiny finish, you can apply a car wax or polish after drying. This adds an extra layer of protection to your car’s paint and keeps it looking great for longer. Some people prefer using a spray-on wax for convenience, while others enjoy the process of applying a paste wax for a deeper shine.
8. Avoid Common Mistakes
While Simple Green is great for cleaning, there are a few mistakes you should avoid. These include:
- Using it in full strength: Always dilute Simple Green with water to avoid damaging the car’s paint.
- Not rinsing thoroughly: Make sure to rinse off all of the cleaner to avoid residue.
- Cleaning in direct sunlight: The sun can cause the cleaner to dry too quickly, leaving streaks. It’s best to wash your car in the shade or on a cloudy day.
- Scrubbing too hard: Avoid applying too much pressure when washing. Let the cleaner and water do the work.
