The foam cannon is a real plus in car washing, by adding a pre-washing step!
It is an unsponsored blog that compared the 9 Best Car Wash Foam Gun or snow foam lances, to appreciate the differences, advantages, and possible negative points.
As a reminder, the foam cannon attaches to your pressure washer gun and allows you to cover the vehicle that needs to be cleaned with rich foam. It is a pre-washing step that is very important.
Indeed, as you are often reminded, pre-washing with a foam gun eliminates a good amount of dirt without contact and that is a very nice advantage. The foam falling or sliding towards the ground, encapsulates dirt and removes it from the paint, without any contact, therefore without risk of scratching the varnish.
It’s a real plus when you include this step in your car wash routine, far from being a gimmick!
Best Car Wash Foam Gun
Washing your car in the summer heat is fun, but adding a can of spray foam can turn the activity into a real blast. Stuck dirt or road salt can damage or corrode a car’s paint or exterior surface, so regular washing is an essential maintenance step to ensure a car’s longevity.
A cannon or foam gun is also a reliable tool for any car enthusiast, especially for those who enjoy off-road driving or live in areas where it snows and there is a lot of salt on the roads.
To set up a fair test for each foam cannon, they are used on the same pressure washer and contain the same dosed amount of product.
Here are the test parameters:
- Foam Cannon Product: Adam’s Mega Foam
- Quantity of product in each foam gum: 30 ml
- Quantity of demineralized water: 475 ml
- High-pressure cleaner: Kranzle 1122 TS T (10 liters/minute – 130 bar)
Of course, if you are doing a test at home, you may need to adjust the amount of foam product for example, as there are different variables that can change the appearance of the foam.
What can cause the foam quality/quality of a foam gun to vary?
Different parameters come into play and can vary the quality of the foam spread on a vehicle, such as:
- The hardness of the water (it is better to benefit from less hard water and/or a water softening system)
- The quality of the pressure washer: the more pressure (PSI) you have, the greater the flow of water and the more rich foam you create
- The quality of the spear used
- The amount of air: adjust by turning the screw above

How To Choose The Best Car Wash Foam Gun (Cannons) | Buying Guide 2022
Soap Concentration Dial
Although it may seem like an easy task at first, no one wants to make soapy water too often. At the same time, it makes no sense to use soapy water in a regular car wash. If the car is not very dirty, nothing is needed or can be handled with a minimum of lather. However, if the car is too dingy or dusty, you may need a little more than normal.
Therefore, make sure that the soap gun container you plan to use is equipped with a densitometer. Most brands offer dialers with five or six concentration settings.
For foam guns, water pressure is probably the most important factor. It is important to maintain an optimal water pressure range. Low pressure is ineffective and high pressure can damage the car body.
A good way to obtain optimal pressure is to consider only reliable brands. You can also opt for a foam gun that allows you to control the water pressure with a lever on the handle.
A filter on the end of a spray gun may at first seem unnecessary. However, water flowing through a hose may contain debris. These particles can also damage the car’s body paint.
To eradicate such cases, it is a wise decision to rely on filters. Moreover, many foam guns have double filters that let nothing pass through.

What is the difference between a foam gun, foam lance, and foam cannon?
No one seems to agree on what each term means, and often they are used interchangeably. However, when asked, cleaners generally agree that a foam gun is a more serious piece of equipment that requires high-pressure water (usually a pressure washer).
If you are using a high-pressure car wash for self-service cars, the foam gun is the way to go. Not only does it have a thicker foam and a faster spray rate, but it can also spray with such force that it immediately begins to pick up dirt.
Foam guns are usually screwed onto a standard garden hose. It works the same way as a foam gun, coating the car with detergent and starting the pre-treatment of the car wash.
It is not as fast or complex, but in the long run, you can get the same good results without the extra equipment if you take the time.
Products sold outside North America are often referred to as foam lances, which is the same term used for foam guns and foam rifles.
What should I consider when choosing a foam gun?
First, “Do you have a pressure washer?” The question is. If so, how much pressure will be produced (how much water can be moved)?
Some can operate at pressures as low as 800 PSI, but most foam guns require at least 1000-1100 PSI to get disappointing results. In addition to pressure, you also need a decent water flow rate (GPM, gallons per minute); requirements vary from 1.3 GPM and up, but 2.0 GPM is probably a safe bet. This flow rate is difficult to achieve with electric high-pressure cleaners.
So if you do not have a gas-powered system, try to find a foam gun with a lower flow rate.
If you don’t have a pressure washer, check out our list of the best garden hose foam guns we’ve found. They work well but are not as good as models that use pressurized water.
Can I use my pressure washer as a foam gun?
As I mentioned in the article on high-pressure washers, you really need to know what you are doing before you point the nozzle of a high-pressure washer at your car. It only takes a moment to start stripping paint, peeling badges, and pushing water under air intakes and seals instead of dirt.
With the right nozzle and settings, a foam gun can be an effective tool for rinsing off dirt before washing, but a pressure washer not only produces foam, it also reduces the water pressure to a safe level. With a pressure washer, the soapy foam can be applied hard enough to not ruin the finish.
Do I need a special soap for my foam gun?
Through trial and error, we have been able to use anything that is safe to use in the car, such as dish detergent. However, this requires a lot of trial and error and can lead to a lot of frustration. Of course, it does not damage the foam gun. Just depends on how much time you want to spend preparing the right mixture.
Foam car washes designed for foam guns, foam cannons, and foam lances include mixing instructions to help you make foam correctly the first time. Many aerosol foams can be combined with soap, but you can use any aerosol foam of any brand.
What is the soap to water ratio for foam guns?
This depends not only on the brand but also on your experience with pressure and the amount of water in your pressure washer.
It varies from less than 1:15, or 2 ounces in a 32-ounce bottle for concentrated, high-end brands, to 1:5 or more. These soaps, even at low concentrations, are suitable for hand washing or deep cleaning with a bucket and chamois skin.
Foam Cannon Tips and Precautions
The most common complaints about foam guns are leaks and broken bottles. Leaks can often be fixed with a few rolls of Teflon tape, which can be found for about $2 almost anywhere tools are sold. I apply it to all threads before use and to the cylinder if a leak occurs.
The only advice is to handle the bottle gently, especially when setting up the foam gun. Remove the spray head and bottle when not in use to reduce the chance of damaging the bottle (and increase the risk of not finding it). It also works much better if stored away from heat, cold, and direct sunlight.
If possible, use a foam gun with clean water after lathering, so it will flow cleanly without soap. This may be included in the car wash. If there is a removable filter, remove it and rinse in the opposite direction to remove anything restricting flow. When putting the foam gun away, look at the seal and make sure nothing has fallen out when you unplug it.
The leading list is dominated by competitors with nearly equal performance. In such a situation, the winner is not so easy to determine. The same problem occurs with whisks. You cannot declare a winner; all you can do is choose the one that is the most ideal Car Wash Foam Gun (Cannons) for you.
Don’t spend a lot of time wondering and hesitating about the final decision. The main thing is to follow the buying guide and have satisfactory customer reviews
