The purpose of foam cannon soap is to act as a pre-cleaning technique before actually washing your car. It loosens the dirt and other grime, which can then be rinsed off after a specified dwell time. A common misconception is that people think that the foam cannon soap is a car wash soap but this is not the case.
Most foam cannons allow users to adjust the water to product ratio for more foam as well as changing the spray pattern width. Some cannons can use a basic garden hose but you will never be able to achieve thick foam without a pressure washer.
If you are looking to add an element of fun to washing your car as well as improve the safety of washing your car, these are the answer. Below is a list of the best foam cannons for your pressure washer that provide effective spraying of foam.

Foam Cannon Buying Guide
Snow foam is a washing mixture that you spray onto your car as a “pre-cleaning” technique. It removes loose dirt and grime to help prevent scratches when you come to washing the car. It also makes it easier to wash your car and it is great fun.
You can use a garden hose for spraying some snow foam onto your vehicle but you will never be able to achieve thick foam. You will need a pressure washer foam gun to produce the desirable thick foam. Once sprayed over the car, you should allow the foam to sink into the dirt and then rinse it off.
When choosing the different types, we highly recommend that you choose one that clearly states that it can be used with foam cannons. The buying guide below should influence your buying decision with the factors you should be considering.
Adjusting the Thickness and Spray
All of the recommended foam cannons above have the ability to adjust the way the spray comes out of the reservoir. Although making the foam thicker doesn’t correlate into a cleaner car, it does provide excellent photo opportunities of your car covered in snow foam.
Reducing the amount of water in the mixture with the snow foam product is how it is made thicker. The cannon will have an adjustable knob that alters the amount of water going from the pressure washer into the snow foam cannon.
On top of adjusting the thickness of the foam, adjusting the vertical size of the spray is just as desirable. You will want to reduce the amount of wastage of snow foam because after all, it is not the cheapest washing product out there.
Many will have a vertical jet nozzle that you can control and easily move to reduce or increase the size of the spray.
The amount of pressure that passes through a foam cannon can be immense and start from 800 all the way to around 4,000 PSI. It is important to check whether your pressure washer will not break through the snow foam cannon reservoir.
The most common flaw with cheap and even the best brand snow foam cannon is that they can crack at the top opening. If the bottle is plastic threaded, avoid it as this will not be durable and it will strip through. The best foam cannon examples will have brass threaded bottles that will not break under pressure.
Foam Cannon Compatibility
As there is a wide variety of pressure washers on the market, its important that you find a foam cannon compatible with your specific washer. Most come with adapters to fit the major brands such as Karcher, Snow Joe, AR Blue and others.
Another compatibility issue that may arise is the fact some foam cannons require a minimum pressure in order to work. Some can be as low as 600 PSI whereas other may require at least 1,000 PSI in order to work.
Before purchasing a foam cannon, you should always check which connector you have and the pressure it provides so that your not left disappointed.
How to use a Foam Cannon
Using the foam cannon is fairly simple and you will need foam soap, the cannon, a pressure washer and water to begin. Once you have what is needed, you can begin setting up your snow foam cannon. Below are brief steps to using your foam cannon.
- Use the specified measurements of soap and water
- Adjust the amount of foam spray
- Adjust the thickness of the foam (less water = more foam)
- Start applying snow foam evenly all round the vehicle
- Let the foam dwell for at least 10 minutes
- Rinse of the snow foam from the vehicle
Using a foam cannon, you can easily cover most cars in less than a few minutes. The only time consuming part is waiting for the foam to sink into the dirt. However, this of course gives you enough time to get a photo of the car covered in foam.
It is important to note that using a foam cannon is suitable for a pre-clean. This means it removes dust, dirt and other debris prior to washing your car, which make it safer to wash. It reduces the amount of debris that may cling onto your car wash mitt, which is great for reducing any damage to the paintwork such as swirl marks.
There are premium and cheap foam cannons available but you should always be aware that cheap alternatives can break easily. Premium examples such as Adam’s and Chemical Guys have been designed by professionals for the best results. However, the price tag is fairly high, which will put many people off.
Our recommendations cover a range of different budgets and only include non-plastic threaded bottles. This is a common fault of cheap foam cannons and is something you will want to avoid.
