How Does Foam Soap Work to Clean Your Vehicle Better Than Other Types of Soap?
The foam soap will create a thick blanket of foam over your vehicle just like how dishwashing liquid soap forms bubbles after mixing with water. The foam will work as an effective lubricant to remove the dirt and debris on the surface of your vehicle. This is especially true for surfaces with scratches and swirl marks on them. You can use a car wash mitt, sponge, or towel to wipe off the dirt and debris, allowing you to clean your vehicle more effectively than with traditional soaps.
Is There a Difference Between a Foam Gun and Soap?
Yes, there are. The foam gun refers to the device that you use to apply your car wash soap. It shoots out the soap in foam form, which then covers the vehicle surface. The best foam gun is one that can provide you with thick foam so that it can lubricate and protect delicate surfaces, such as paint, from scratches and swirls. The foam will also be soft and cushiony, allowing you to wipe off dirt and debris more effectively.
What Are the Benefits of Using the Foam Cannon Soap?
There are several benefits to using foam cannons soap over traditional car wash soaps.
- Foam soap makes it easier to clean your vehicle.
- You can completely avoid scratching the surface of your vehicle.
- It will protect the surfaces from swirls and scratches.
- The foam will leave a layer of protection on your vehicle, preventing dirt and debris from sticking to it.
- The foam soap is ideal for washing large vehicles, such as trucks and SUVs.
What Are the Types of Foam Cannon Soap?
Before you purchase any foam cannon soaps for your car detailing, you need to understand that not all products are created equal. There are 2 types:
1) Industrial strength car wash soap.
These are perfect for heavy-duty situations such as commercial auto detailing or car washes. You can use them to remove dirt and debris from the paint, chrome, wheels, bodywork, rubber, and plastic components of your vehicle. They have a pH of 8 – 9.5 and can provide you with a thick layer of foam that will lubricate each surface for you to clean properly without scratching it with your dirty wash mitt or sponge.
2) Unique car wash soap.
This type of foam cannon soap is only for the purpose of cleaning your vehicle. They work by simply soaking the dirt and debris in the water and they will lift it off from the surface. In most cases, these products contain a pH between 4 – 7 and can’t provide you with a thick layer of foam that will lubricate each surface for you to clean properly without scratching it with your dirty wash mitt or sponge.
If you are looking for a foam cannon soap that can provide you with a thick layer of foam, then choose an industrial-strength foam soap.
What You Should Look for in a Foam Cannon Soap
#1 Foam Thickness
The thickness of the foam is one of the most important factors in determining which foam cannon soap you should purchase. The thicker the foam, the better it will lubricate and protect your vehicle from scratches and swirls in a car wash or a car wash tunnel.
This is why not all foams are suitable to use in a foam cannon. If the foam is too thin and you use it in a foam cannon, then it will not be able to protect your vehicle from scratches and swirls.
Look for products that contain sulfate surfactants, such as alkyl dimethyl amine oxide (LAS) and sodium laureth sulfate (SLES). These products will create the kind of thick foam that you need for a car wash or a car wash tunnel.
#2 Foam Duration
Foam duration refers to how long your vehicle stays covered in foam. If it doesn’t stay on for a long time, then you may need to add more soap into the mixture when using a foam gun or cannon. This is especially true if the car wash soap is thick and contains strong surfactants such as LAS and SLES.
If you add in too much soap, then it can cause foaming and bubbles to form on your vehicle and they may damage the finish in some cases.
Even though your vehicle will be covered in foam for a short period of time, it does its job in protecting the surface from getting scratched by dirt and debris.
#3 pH Level
The pH level of the foam is also important in determining the type of foam cannon soap you should buy. The pH level determines how much soap is in your product and therefore, it will affect the appearance and the performance of the foam.
An industrial-strength car wash soap has a relatively neutral pH (around 7-9) which means that it contains little to no acid. The foam will stay on the vehicle for a longer period of time too. A unique car wash soap has a pH between 4 – 7 which means that it is slightly acidic. It will not stay on your vehicle for a long period of time and it may have adverse effects on the paint.
#4 Foam Volume
The volume of the foam is important because depending on your use, you may need more or less foam in your car wash soapy mixture. A foam gun will typically allow you to shoot out the foam 12 feet, while a foam cannon will typically allow you to shoot out the foam 25 feet.
If you are going to use a foam gun or a sprayer, then look for products that can produce a relatively thick layer of foam. However, if you are going to use a foam cannon, then a product that creates a small amount of thick foam is ideal.

The first product that I want to mention comes from Mothers brand, Mothers Triple Action Foam Wash. One thing that I really like about this product is that it provides you with the thickest layer of foam.
You just have to spray it onto your vehicle and you will see the thick layer of foam. This is perfect for car detailing since it will lubricate each surface giving you a cleaner, more effective car wash.
The pH level of this product is within the acceptable range (pH 5-9), which means that it produces a rich, thick foam without damaging your vehicle’s paint or other surfaces. The foam will stay on your vehicle for a decent amount of time, approximately two minutes.
This is also ideal for car detailing since it provides you with enough time to thoroughly wash your vehicle. The foam will protect your vehicle from swirls and scratches while it cleans the dirt off the paint, chrome, wheels, bodywork, rubber, and plastic surfaces.
Also, it won’t damage any protective layers such as a ceramic coating or wax. The one thing that I don’t like about this product is that it produces a bit of froth when using it in a foam cannon or gun.
- Foamy and thick
- Acceptable pH level

#2 Chemical Guys Snow Foam Soap and Cleanser

- A WHOLE NEW LEVEL OF FOAM – The key to a clean...
- BUCKET, FOAM GUN OR CANNON – Whether you are...
The second product on my list is Chemical Guys Snow Foam Soap and Cleanser. This is a concentrated foam that contains no water. This is the reason why it can get your vehicle completely wet by providing you with a thick, rich layer of foam without dripping water all over your car. It provides you with a long level of protection while remaining in the car for a decent amount of time.
As this product is highly concentrated, you can save money on the soap in comparison with other products.
It gives you roughly 20 applications per container, which is enough for a whole car wash. All you need to do is to use 1 oz of the soap and 4-5 drops of very gentle dishwashing liquid or degreaser.
The foam will stay on your vehicle for a good period of time and it protects your paint from swirls and scratches, while also cleaning all dirt and grime off the paint and other surfaces.
This is also a pH-neutral product, which means that it is very effective at protecting your vehicle’s paint from damage.
One thing I don’t like about this product is the scent. It’s fruit-scented, which I think not appropriate for cars. Anyway, the scent is light and unnoticeable after a while.
- A thick layer of foam
- Protects your vehicle from swirls and scratches
- Can be used in a foam cannon
- Gets completely wet when sprayed onto the vehicle
- No harm to ceramic coating or waxes.
- The foam provides you with adequate protection against the damaging effects of dirt and grime.
- Fruit-scented soap
> What I like: If you’re looking for a concentrated type, this is the right one!
#3 Adam’s Ultra Foam Shampoo
The third product on my list is the one from Adam’s, Adam’s Ultra Foam Shampoo. It produces a nice thick layer of car wash foam that stays on your vehicle for a considerable amount of time. It rinses off easily as well which makes it ideal for people who don’t want to spend too much time getting rid of all the soap and residues.
This product contains no ammonia-based ingredients, which makes it easier to rinse off. It also contains polymers and acrylics, which are abrasive enough to scrub off the dirt and grime from your vehicle’s paintwork. The foamy substance that is created by this product is thick, rich, and long-lasting.
The ingredients in this product are perfect for producing a thick, rich foam without hurting the quality of your vehicle’s paintwork or affecting any protective coating.
It’s suggested to use pressure washers with PSI 870-3190 or GPM 1.3-5.3.
One downside of this foam shampoo is its price. It’s one of the most expensive one on the market.
- Rich foam
- No harmful ingredients
- Rinses easily
- Most expensive
> What I like: Looking for the thick foam type but quickly rinse off! Look no further than Adam’s Ultra
#4 Sun Joe Premium Snow Foam Soap
- Questions, Text 563563 to chat directly with a Sun...
- CONCENTRATE: Pressure washer concentrate formula
- SAFE: Biodegradable, safe on metal surfaces
Another great product is Sun Joe Premium Snow Foam Soap. Sun Joe is a big name for pressure washers and they make soap as well. This product is designed to be used with a pressure washer and it’s reasonably priced. It produces a thick layer of foam that stays on your vehicle for a considerable amount of time.
As it’s a biodegradable formula, it won’t harm your vehicle’s paintwork. The foam is thick, rich, and long-lasting. However, you can reduce its thickness by using less product (it makes much foam) or by increasing the pressure of the water (which creates a thinner foam).
You will need to apply 2-3 ounces of soap for one car, make sure you keep it well after adding soap. It requires a pressure washer to wash your car. However, you can also use it to clean your garden deck or pavement.
One downside of this product is that it’s not concentrated so it runs out fairly quickly.
- The foam is thick, rich, and long-lasting
- No harmful ingredients
- It can be used to clean your garden deck or pavement.
- Reasonably priced
- Runs out quickly
> What I like: A biodegradable formula foam soap specialized for pressure washer!
#5 Bilt Hamber Auto Foam Soap
Bilt Hamber Auto Foam Soap is another great product that cleans, protects, and maintains your vehicle. It produces a thick layer of foam on your vehicle, which will provide you with a long-term level of protection. This product is highly concentrated so it’s recommended to dilute it before using it.
This item received many positive feedbacks from users because of its cleaning power. You literally don’t have to do much but you can get the best result. The formula is made from natural ingredients and it leaves a fresh scent on your vehicle. The formula is biodegradable, which means that it won’t harm your vehicle’s paintwork.
It quickly removes the dirt and grime while protecting the paintwork from swirls and scratches. It’s also concentrated so you only need to use a small amount to wash your car.
As this product is concentrated, you can save some money on it as well. The price for one bottle is rather high but you can use it for more washings than other products.
One downside of this product is that you should apply it on a painted surface only.
- The foam is thick, rich, and long-lasting.
- No harmful ingredients.
- High concentration
