Why Make Your Own Car Wax Spray?

As a car owner, I know the importance of keeping my car looking shiny and new. That’s why I prefer to make my own car wax spray.

Not only is it cost-effective, but it also gives me more control over the ingredients and the final product.

Here are a few reasons why you might want to consider making your own car wax spray:

  • Cleaning: A good car wax spray can help remove dirt and grime from your car’s surface, leaving it looking clean and shiny. By making your own spray, you can customize the cleaning agents to suit your needs and preferences.
  • Quick Detailer: A car wax spray can also be used as a quick detailer to remove light dust and fingerprints from your car’s surface. Having a bottle of homemade spray on hand can save you time and effort when you need to quickly clean your car before a date or a meeting.
  • Slick: A good car wax spray can also make your car’s surface feel slick and smooth to the touch. This can help reduce drag and improve your car’s aerodynamics, which can translate into better fuel efficiency.
  • Rain: A car wax spray can also help repel rain and other forms of moisture from your car’s surface. This can be especially useful during the rainy season when you want to protect your car’s paint from water damage.

Overall, making your own car wax spray can be a rewarding and practical DIY project.

With just a few simple ingredients and some basic equipment, you can create a product that will help keep your car looking its best for years to come.

Ingredients for Making Car Wax Spray

Carnauba Wax

One of the key ingredients in making car wax spray is carnauba wax. This wax is derived from the leaves of the carnauba palm tree, which is native to Brazil.

Carnauba wax is known for its ability to provide a deep shine and protect the car’s paint from UV rays and other environmental factors.

It is also a common ingredient in many commercial car waxes.


Water is another important ingredient in making car wax spray. It is used to dilute the wax and make it easier to apply to the car’s surface.

It is important to use distilled water to avoid any impurities that may be present in tap water.

Other optional ingredients that can be added to the car wax spray recipe include:

  • Beeswax: Beeswax can be added to the recipe to provide additional protection to the car’s paint.
  • Olive oil: Olive oil can be added to the recipe to help condition the car’s paint and prevent it from drying out.
  • Pine oil: Pine oil can be added to the recipe to provide a pleasant scent and help repel insects.

When making car wax spray, it is important to follow a recipe that includes the correct amount of each ingredient.

Adding too much or too little of any ingredient can affect the performance of the wax and may even damage the car’s paint.

How to Make Car Wax Spray

Step 1: Melt the Carnauba Wax

I start by melting 1 cup of Carnauba wax in a double boiler.

This process takes about 10-15 minutes. Once the Carnauba wax has melted, I remove it from the heat and let it cool for a few minutes.

Step 2: Mix the Carnauba Wax and Water

Next, I add 2 cups of distilled water to the melted Carnauba wax and stir it well. Then, I add 1 tablespoon of rubbing alcohol to the mixture and stir it again.

This helps to emulsify the wax and water mixture.

After that, I add 1 tablespoon of dish soap to the mixture and stir it again.

This helps to remove any impurities from the Carnauba wax and ensures that the spray wax will be clean and effective.

Step 3: Pour the Mixture into a Spray Bottle

Finally, I pour the mixture into a clean spray bottle and shake it well to ensure that all the ingredients are well mixed.

I prefer to use a glass spray bottle because it is more eco-friendly and reusable.

However, you can also use a plastic spray bottle if that is what you have on hand.

Now, your homemade car wax spray is ready to use!

Simply spray it onto your car’s exterior and wipe it off with a clean microfiber cloth to reveal a shiny, protected finish.

Tips for Using Car Wax Spray

If you’ve decided to make your own car wax spray, congratulations! Here are some tips to help you use it effectively:

Tip 1: Clean the Car First

Before applying the wax spray, make sure your car is clean and dry. Any dirt or debris on the surface can scratch your paint when you rub in the wax.

You can wash your car with soap and water, or use a waterless car wash product if you’re short on time.

Tip 2: Work in the Shade

It’s best to apply wax spray in a shaded area, away from direct sunlight.

This will prevent the wax from drying too quickly and leaving streaks.

If you have to work in the sun, try to work on one small section at a time, and buff it off before moving on to the next section.

Tip 3: Use a Microfiber Towel

When applying wax spray, use a clean microfiber towel. This will help prevent scratches and swirls in your paint.

Fold the towel into quarters and spray the wax onto the towel, not directly onto the car.

Rub the wax onto the car in circular motions, working on one section at a time.

Tip 4: Test in a Small Area First

Before applying the wax spray to your entire car, test it in a small, inconspicuous area first.

This will help you make sure the wax doesn’t damage your paint or leave any residue.

If you notice any problems, stop using the wax spray immediately.

Tip 5: Avoid Direct Sunlight

After you’ve applied the wax spray, avoid exposing your car to direct sunlight for at least an hour.

This will give the wax time to cure and bond to the paint.

If you expose your car to sunlight too soon, the wax may melt and streak.
