Best Soap for Foam Cannon: Which One Is More Effective


To find the best foam cannon soap, you need to analyze. You probably already have a pressure washer and a foam cannon, and you’ve probably tried washing your car with ordinary car shampoo/soap with these tools.

Using a conventional auto shampoo to pressure wash your vehicle wastes time since it doesn’t have enough chemical concentration to generate a lot of foam.

With a foam cannon and a high-pressure washer, foam soaps create a thick lather on the automobile. Because of this, they’re also recognized to be more effective than ordinary vehicle soaps in several ways.

Today Hammer and Coop find out 10 foaming car washes for you. Read the full review if you want proper guidelines about these top picks.

What Is Foam Cannon? 

With a Foam Cannon or Foam Lance, you may update your Two Bucket Wash Process with a gas or electric pressure washer.

Foam Cannon

While Foam Cannons are a lot of fun to use, their main aim is to make washing considerably safer by eliminating the likelihood of swirl marks and other damages.

Three elements make up the Foam Cannon: a solution container, suction tube, and adjustable barrel. It sprays a thick layer of soapy foam solution on a car, thus the name Foam Cannon.

Additionally, the 1/4-inch male quick-connect fitting on the Foam Cannon allows it to be used with most pressure washer wands that include a 1/4-inch female quick-connect fitting.

Adapters and new wands, and trigger assemblies are required for some pressure washers, such as the Adam’s Snub Nose Attachment.

Do you Know How the Foam Cannon Functions?

A pressure washer and other washing equipment are all you need to start, making the process a cinch once you get them set up.

To begin, attach the clear suction tube to the bottom of the barrel using the plumbing fittings.

Next, add water to the Foam Cannon container until it reaches the top of the label, roughly four-fifths of the way complete. It is then time to add your favorite soap.

To get the thickest and most foamy lather, we recommend our Ultra Foam Shampoo.

Make sure to properly insert the bottle into the barrel of the Foam Cannon before giving it a few good shakes to ensure a uniform distribution of soap and water solution inside the barrel.

After preparing the Foam Cannon, it’s time to clean the vehicle. 

Pressurized water should be kept from painted surfaces at least 12″-18″ to prevent splashing.

So How It Works?

Connect the pressure washer to the Foam Cannon next. You’ll get the best fit when you crank the top adjustment knob clockwise, then back it off approximately a quarter-turn.

To get a 1-2mm gap between the two vertical metal vanes, revolve the barrel.

You may begin foaming down the car by modifying the Foam Cannon’s settings as needed. The foam should be allowed to sit on the surface for a while. Loosening and lifting grime will begin with the soap.

Soap will not adhere to a ceramic-coated or newly clayed, polished, and protected car for long because the surface is so slippery. This reveals how effectively the surface is protected.

Before employing the Two Bucket Wash Method, you can use the pressure washer to rinse the foam down again to lubricate the surface.

10 Best Foam Cannon Soaps Reviews – Our Top Picks

Car wash soap for foam cannon offers several advantages. To achieve the most acceptable results, you must use suitable soap. 

Let’s see an in-depth review of our selected top picks downward:

1. Chemical Guys CWS_110 Honeydew Snow Foam – Best Overall

Top Characteristics

  • Benzyl Salicylate is the main ingredient.
  • Vehicle Exterior surface recommendation.
  • 128 fl oz (1 Gallon) package.
  • Honeydew Scent.

Vehicle care chemicals, car wash accessories, polishing pads, and machinery are all specialties of Chemical Guys. It’s a global manufacturer.

It works well with foam cannons, foam guns, bucket washes, and other cleaning methods.

However, the Chemical Guys CWS 110 Honeydew Snow Foam delivers a touch-free vehicle wash while reducing surface damage. 

Moreover, it uses advanced technology to develop super-premium polymers and hyper surfactants that release dirt and dust, allowing them to be washed away without scratching the surface.

Honeydew Snow Foam Cannon Soap leaves no trace and even includes water softeners to help remove hard water stains.

To wash any color paintwork or exterior car material, use the pH-neutral composition in direct sunshine. It’s mild on wax.

Furthermore, Honeydew Snow Foam is soft enough to clean your car’s wheels and paint.

Use the Honeydew Snow Foam Cannon Soap with water to generate a thick, white snow foam that may be used in a bucket or an air-powered foam cannon, lance, or washer.

It comes in three convenient sizes:

  • A 16-ounce container that fits anywhere.
  • A 64-ounce bottle that can be used for several washes.
  • A 128-ounce bottle.

The price of the 128-ounce bottle is around $30. Honeydew and watermelon are the two scents offered for the Honeydew Snow Foam.

Temperatures below freezing might damage this product; thus, it should be stored indoors throughout the winter months.


  • pH-balanced chemicals are used.
  • Washes faster with lubrication.
  • Harmless.
  • Stops streaks.


  • To remove difficult dirt from your automobile, you need at least two layers.

2. Adam’s pH Neutral Ultra Foam Shampoo – Runner Up

Top Characteristics

  • Surface Recommendation for Plastic & Rubber.
  • pH Neutral.
  • Ultra Slick Formula.
  • 128 Fluid Ounces volume.

For the second pick, I’m recommending Adam’s Ultra Foam Shampoo, a foam cannon soap that has long been one of the biggest sellers in the company’s line of high-quality detailing products.

Foam shampoo removes dirt, filth, and impurities from your car quickly and easily, and the lubricant it includes prevents your automobile from being scratched while you wash it.

You may use the foam to wash your automobile without fear because it is safe for all outside parts of your vehicle’s exterior, including paint, glass, tires, and bare metal.

As soon as you apply this concentrated foam soap to your vehicle, it begins to do its work immediately. 

Moreover, unlike many other regular foam soaps, it doesn’t rapidly evaporate if you become busy anywhere after applying them.

Furthermore, this foam cannon soap’s pH (potential of Hydrogen) is well balanced so that it won’t remove any wax or sealant from your car. 

A thin coating of protective polymer-based chemicals is created when you rinse your car, leaving no streaks and giving your automobile an unmatched shine.

It’s advisable to use 2.5-3 ounces of this soap and 1 gallon of water to get the thickest foam possible. 

In addition to its pleasant scent, this soap makes car cleaning an enjoyable experience.


  • Ultra-smooth formula.
  • ph-neutral
  • No streaks.
  • Speedy action.
  • Forms a shield.
  • Keeps longer on your automobile.


  • No potential cons.

3. Sun Joe SPX-FCS1G-CRM Premium Snow Foam – 3rd Best Pick

Top Characteristics

  • For the wood & metal surface.
  • Orange-Vanilla aroma-based.
  • Biodegradable.
  • Safe on metal.

Sun Joe’s premium snow foam is our third favorite, but that doesn’t detract from the quality of the goods I’ve just described.

When it comes to getting the most remarkable results, Sun Joe devised this soap with a chemical composition that is highly concentrated and quickly soaks up tough dirt and pollutants. Although the soap isn’t as thick as some other soaps, it still performs its job.

Because our foam cannon soap is biodegradable, it doesn’t harm your car’s exterior, allowing you to wash your vehicle in whatever way you like. This soap won’t remove the wax or sealant covering because of its biodegradable nature.

It is necessary to properly rinse your automobile at least twice with clean water to remove even the tiniest remnants if you want a streak-free finish. There are no scratches to worry about because it is soft enough to protect the automobile during the wash.

Foam soap users advise against diluting it since it doesn’t produce a lot of suds, to begin with, and if you try to use it with water, it may just slide off the car.


  • Provides a great wash gently.
  • Biodegradable formula is used.
  • Stable pH level.
  • Streaks are not left behind.


  • Compared to other foam soaps in the same market sector, this one is less concentrated.

4. Bilt Hamber Snow Foam Car Wash Soap

Top Characteristics

  • For the painted surface.
  • 5 Liters volume.
  • Auto-foam.

This vehicle wash is provided by Bilt Hamber, a well-known brand in the auto detailing industry. 

It’s a concentrated, biodegradable soap with a very high pH; it’s gentle on paint since it doesn’t include acidic components, and it’s less expensive than Sun Joe’s product because it doesn’t run out in only a few washes.

Initially, we were skeptical about it since the foam it produces (produced from roughly 12 liters of concentrate mixed with a gallon of water) is thinner than the ones we’ve described. Bilt Hamber, on the other hand, has a good handle on things. 

Using the foam cannon soap’s surfactants removes even the most stubborn filth and grime in only a few minutes.

A five-liter jug costs a lot of money, and it will only last approximately ten washes at the suggested dilution levels. 

While the foam seems to flow from your car very quickly, you’ll find that your car is almost clean and ready for a sponge wash once you get over that. It’s both surprising and remarkable.


  • Premium quality.
  • Reliable performance.
  •  Foaming water-based.
  • Non-caustic formulation


  • Expensive.

5. Chemical Guys CWS21364 Mr. Gold Foaming Car Wash Soap

A clean and shining finish is guaranteed with Mr. Gold since there is no residue left behind after he rinses the vehicle.

  • 128 fl oz (1 Gallon).
  • Cherry Scent.

It has a unique chemical composition that melts grime and pollutants in only a few minutes, ensuring a scratch-free wash.

This foam soap doesn’t remove the wax or sealant covering since it has a balanced pH. Only the unpleasant things are neutralized. 

Also, it’s safe for many kinds of surfaces, including plastic, vinyl, glass, paint, etc., and has a pleasant aroma that makes you look forward to washing your car with it.

Factors To Consider Before Buying The Best Soap for Foam Cannon


First and foremost, whether or not a foam cannon soap is concentrated or diluted is one of the most significant characteristics to check for when purchasing one.

Using a concentrated foam cannon soap is preferable since you can adjust its efficiency by adding water to it. On the other hand, because the diluted soap is already thin, you will be unable to adjust its consistency.

A concentrated foam cannon soap is also more effective on stubborn dirt or impurities since the quantity of chemicals used is higher, allowing it to cut through unwanted material than regular soap more quickly.

If you want a foam soap that will remove less filth, you may use the diluted soap. However, it is highly advised that you use concentrated soap since it is superior to diluted soap in many ways.

Well, most high-quality soaps are available in concentrated form to better fit the needs of their customers, and all of the soaps I’ve listed in this post are concentrated, except the last one, which is extremely low in concentration.

pH (Hydrogen Concentration)

Consider if the pH value of the foam cannon soap is balanced/neutral or not before using it to wash the tough dirt and grime from your vehicle.

If the pH of the soap is near 7, if it is 6.5 or 7.5, it will perform at its best, and high-quality soaps have this pH level in their formulation. So choose a foam cannon soap that is pH-balanced or pH-neutral to achieve the best results.


It is often assumed that thick foam is more effective at cleaning, which is correct. For those considering purchasing a foam cannon soap, it is essential to understand how much thick foam it produces.

The majority of foam cannon soaps are designed to produce thick foam or suds so that the users can quickly get the job done without having to touch their cars very much at all.


When it comes to washing an automobile, people use two practical approaches. The first way is known as the two-bucket method, while the second method is known as the foam cannon method.

If you want to use the second approach, you should go for the foam cannon soap, specifically developed for use with the foam cannon.

For those who prefer to employ both ways, they may select the one that is the most adaptable to their needs and is suitable with both bucket and cannon approaches.


When it comes to quality products, we all know that we have to pay a premium for them. And because we’re talking about soaps, it wouldn’t be wise to wash your car with a low-quality soap.

The use of a low-quality soap increases the likelihood of ruining the car’s paintwork, ultimately resulting in you having to pay more money to have it repaired.

Always be sure you purchase foam cannon soap from a reputable manufacturer. Because of its chemical makeup, it may be a little more expensive for you, but it will ensure that your automobile is not harmed.

So that was a brief discussion of a few critical considerations to bear in mind when purchasing a foam cannon detergent.

Spray Soap by Foam Cannon with Pressure Washer


Consider purchasing a high-quality soap made explicitly for foam cannons to get the most out of your pressure washer and foam cannon and get a better wash.

When using your foam cannon with a regular soap/shampoo, you may not get the most outstanding results since it is not sufficiently concentrated.

That was all about the 10 most incredible foam cannon soaps we discovered via extensive investigation. I hope that you have gained anything from reading this post. Hammer & Coop wish you all the best!


A superb leather with foam cannon soap requires how much pressure?

Foam cannon soap should produce a rich lather at a PSI of 1,500 to 3,000 at a GPM of no less than 1.5 and no more than 5.

Does a foam cannon accept any soap for use?

Yes, you may use ordinary soaps and detergents in a foam cannon, but there is a significant difference.

Foam cannon soaps produce rich and thick suds, but they also shield the surface against scuffs.

How much soap should I put in a cannon before firing it off?

The amount of solid foam cannon soap and warm water needed for a single wash is little more than 3 to 4 ounces each.

Do foam cannons accept any soap?

Foam cannon soaps can be manufactured from regular soaps and detergents, but there is a distinction between the two.

As well as generating thick and rich suds, foam cannon soap also protects the surface from abrasion. Pressure washer pumps can be damaged by ordinary soaps that aren’t explicitly designed for the task.
