5/5 - (5 votes)

Have you ever witnessed scratches and swirl marks on your car after the car wash? Do you want to know how they appear on your car out of nowhere?

That’s only because you didn’t apply snow foam before actually washing your car. Going with the pre-wash one out of ten times doesn’t make much of a difference. Pre-washing is a prerequisite for car washing that you or anyone else out there shouldn’t miss at any cost.

What is Snow Foam and How to Make a Snow Foam Car Wash at Home?

Snow foaming is a pre-wash that not only removes dirt or grime but also avoid scratches and swirl marks which can be very hard to remove and hence would require another hefty procedure for you to go through. It saves you the effort of using wash mitts that usually tarnish cars’ exteriors after a car wash.

But still many people out there, instead of going for the pre-wash, go for the car wash directly.

Why Don’t People Prefer Pre-wash Before A Car Wash?

If you are a car enthusiast then you would be aware of the high-quality snow foams available in the market that are easy to apply resulting in shiny outcomes. However, people oftentimes go directly with the car wash due to the following reasons:

  • The high prices of the ready-made snow foams.
  • And the non-stop trips to the market every time, just to buy snow foam before a car wash.

That’s not all. In case if you think that ready-made snow foam is the only solution every time you wash your car then you are thinking it all wrong because you can make your snow foam at home.

How to Make Snow Foam Car Wash at Home?

To make your own snow foam car wash, all you need is a bucket of water, a quarter cup of white vinegar or baking soda, and a quarter cup of baby shampoo or a dishwashing liquid. Add the baking soda and dishwashing liquid in a bucket filled halfway with water, and boom you have got your homemade snow foam ready with just 3 components.

But that’s not all. Making snow foam is not that much of a deal than applying it. Yeah, you read it right. Car detailing experts would agree with me on this that applying snow foam car wash is quite a task that requires undivided attention and extra care.

What is the Right Way to Apply Snow Foam on the Car?

To start with the right way to apply snow foam on your car, first, you need to make sure that you have everything that is required to apply the snow foam which includes:

  • Snow foam cannon or lance: The snow foam lance is a particular type of nozzle designed to draw the snow foam from the container through a mesh to remove the dirt even from the smallest of the corners. 
  • High-quality foam pistol: Next thing that you need is a high-quality foam gun, an essential car washing equipment to mix the right amount of snow foam, water, and air to generate the adequate consistency of snow foam suitable for a good wash.
  • Pressure washer: A high-quality pressure washer is yet another thing that you should have or should buy to provide your car with the right pre-was that it deserves. A genuine high-powered pressure washer ensures that the snow foam is applied with adequate pressure that adheres best to your car.

With the right equipment in hand, get ready for your shiny car to make an appearance because pre-washing with snow foam can never go wrong.

Things to Be Considered Before Applying the Snow Foam Car Wash

Now, there are certain things that one must keep in mind before applying the snow foam car wash.

  • Make sure you mix the right proportion of handmade snow foam with water in the snow foam cannon. Ideally, it is preferred to mix three parts of snow foam with one part of water to make sure that the consistency of the snow foam is effective enough to adhere to the car. Too much water can dilute the solution which could result in the sliding of snow foam from the car.
  • If you are using ready-made snow foam then make sure you read the recommended dilution ratio which usually lies in the range of 1:10 to 1:20. By following the guidelines, there is a high chance that you would end up with the right consistency. However you could always check, test the solution by applying it on a patch first to fix it accordingly, if required.

How is a Snow Foam Car Wash Better than Car Shampoo?

Snow foam with little lubrication works more effectively than a car wash. It loosens the grease, dirt, and muck from the car without any extra effort by sticking to the car’s body.

However, car shampoos with more lubrication slide off from the car and hence require the extra effort of wiping the dirt with a wash mitt or something. Wiping the car is no big deal but the wiping part often results in micro scratches on the car.


Pre-washing is the most crucial step before a car wash that most of us don’t bother ourselves with. However, if you always want your car to shine then there is no other way than to go for a pre-wash with snow foam.

Several car detailing experts around the world believe that it’s important to pre-wash your car in the right way. It doesn’t matter whether the snow foam is ready-made or handmade. What matters is the right equipment and the right technique required to apply the snow foam.

If you are tired of going for pre-wash then follow the above-mentioned tips and tricks to get the desired outcome at home.

Frequently Asked Questions (FAQs)

Is it required to apply water before snow foam?

No, it is not required to apply water on the car before applying snow foam as it would result in excess lubrication that would not let the snow foam adhere to the car.

Should we use hot water to get the right consistency of snow foam?

Some myths say that using hot water would result in the right consistency of snow foam. However in reality, it doesn’t make much difference because, by the time you get the right consistency to start working with, the water would be cold already.

Do I need a foam cannon or pressure washer to make snow foam?

While it’s possible to make snow foam without them, a foam cannon or pressure washer with a foam gun attachment is highly recommended. These tools help create thick, clinging foam that covers your car efficiently.

Can I use homemade snow foam on any type of car paint?

Homemade snow foam is generally safe for all car paint types, including clear coats, as long as you follow proper washing procedures. Avoid using harsh chemicals and abrasive brushes that could damage the paint.

Is homemade snow foam as effective as commercial products?

Homemade snow foam can be just as effective as commercial products if mixed correctly and applied properly. It may require some trial and error to find the right formula for your car and cleaning needs.

Are there any environmental benefits to making homemade snow foam?

Making your snow foam at home allows you to choose eco-friendly ingredients, reducing the environmental impact compared to some commercial products. You can also reuse containers, minimizing plastic waste.

Can I store homemade snow foam for future use?

Yes, you can store homemade snow foam in a sealed container for future use. However, it’s best to use it within a reasonable timeframe, as the effectiveness of the foam may diminish over time. Shake well before each use if it separates.
