Do you want to know about Foam Cannon? Hand-washing a car, especially a bigger one like a pickup truck or SUV, can take a lot of time and work. A foam cannon can make things easier. When you use a bucket and a wash mitt to wash your car by hand, you might run out of suds. Foam cannons shoot a steady stream of foam, so you don’t have to stop and fill a bucket to finish the job.

Foam cannons also shoot out thicker soap than a wash mitt, which means you don’t have to scrub as hard to get rid of dirt and grime. Attached to a pressure washer, foam cannons are a great addition to your car washing arsenal because they are effective, easy to use, and get the job done in less time.

What is a Foam Cannon?

The Foam Cannon has three parts: a bottle of solution, a tube for sucking up air, and a barrel assembly that can be changed. It is called a “Foam Cannon” because it sprays a very thick layer of soapy foam solution on the surface of a vehicle. Before touching the surface with a Wash Pad or Wash Mitt, this thick shampoo foam helps loosen and lift dirt. It also keeps the surface lubricated with a safe, pH-neutral soap like our Ultra Foam Shampoo. The best way to keep the surface from getting swirl marks or water spots from hard water while washing is to keep it lubricated.

How Does it Work?

Once you have set up your pressure washer and all of your other cleaning supplies, like buckets of water, Wash Pads, drying towels, and so on, it’s easy to use. First, attach the clear tube that draws in air to the brass fitting on the bottom of the barrel. Next, fill the Foam Cannon bottle with water until the label on the bottle is about halfway up. Then you’ll need to add the soap you want.

All of the soaps from Adam’s Polishes work well in the Foam Cannon, but some work better than others. Our Ultra Foam Shampoo has the highest concentration and makes the thickest foam. Pour about 3–4 ounces of Ultra Foam Shampoo or the soap of your choice into the bottle, carefully thread it into the barrel of the Foam Cannon, and then give the bottle and barrel a few good shakes while holding them with both hands to make sure the soap and water are mixed well. Now that the Foam Cannon is set up and ready to go, it’s time to wash the car.

Does Foam Cannon Clean Better?

It will depend on the type of foam cannon you have and the soap you use. But foam cannons will usually clean better than bucket washes or garden hoses. It does a better job of cleaning because it covers dirt with a thick layer of suds.

When you use a foam cannon to clean, dirt and grime rarely stand a chance. Again, though, the results will depend on the soap and cannon you use. I really like using the Foam Cannon from Tool Daily and the CWS 110 Snow Foam Car Wash Soap from Chemical Guys. This combination has helped me clean the surface of my car or truck like nothing else.

When Should You Use a Foam Cannon?

There are times when it’s good to use a foam cannon. The best thing about using one is that you can add more grease to a car when you wash it. This is helpful for cars with paint that is soft and easy to scratch as well as ones that are really dirty. If you spray foam on the surface right before you start to wash with your mitt, it will stay extra smooth and less likely to scratch.

Using a foam cannon with a stronger soap to remove any remaining wax or sealant from a car before putting it back on or doing a paint correction can be very effective. Most of the time, this is what you see pros do in online videos. People who do their own detailing see this and think that their regular ph-neutral soap will do the same thing. But it doesn’t. You need to use a cleaner that can be used for many things or a strong soap made to remove wax and grease.

Things to Consider Before Buying a Foam Cannon

Pressure Washer Requirements

When you buy a foam cannon, there are two things you should pay attention to. The first thing is how fast water moves through the cannon.

Many of them can handle up to two gallons of water per minute (GPM). This quality will be listed with the pressure (in pounds per square inch, or psi). So, check the specs of your power washer and make sure they match the specs of the foam cannon you choose.

Bottle Size and Shape

The shape of the foam cannons that different companies sell is one way that they stand out from each other. Most bottles can hold about one litre or 32 to 33 ounces, but you should pay attention to the shape of the bottle itself. The majority of foam cannons look like scuba tanks. The cannon has a short, wide neck and wide shoulders that drop straight down its length. Some manufacturers, though, add a twist that makes it easier to hold the cannon while loosening or tightening it.

GPM and PSI

Once you’ve chosen the type, there are two things you need to check: the water flow rate (in gallons per minute) and the pressure rate (in pounds per square inch). Most people choose between 2 GPM and 1000-3000 PSI.

Water Spray Pattern

This is important if you want to concentrate the water in one spot or let it sprinkle over the whole car. Pattern compatibility should be the same for both the pressure washer and the spray cannon.

Quick-Release or Quick-Detach

You probably won’t have to look for a quick-release foam cannon because most products on the market come with this feature already. You will need to make sure, though, that the platform you are using can fit the quarter-inch fitting that most foam cannons have.

There are ways to make your platform work with a quarter-inch fitting, but it’s best to know about this before you buy something. With quick-release fittings, you can store the pressure washer without the foam cannon attached, and it’s easy to switch between spraying foam and rinsing the car.

Dilution Ratio

Your foam cannon should let you change the amount of soap, foam, or shampoo to water so you can control how far the foam goes.

What PSI is Good for Foam Cannon?

When looking at foam cannons, most experts and Reddit agree that 1500 PSI is a good starting point. This number will be good enough for black cars and other similar cars. Moreover, it won’t use as much water as higher PSI options.

The Westinghouse ePX2000 Electric Pressure Washer with Detachable Foam Cannon is a great example of one of these. It’s a bit expensive, but it has all the features of a pressure washer and foam cannon in one handy device.

Are Foam Cannons Worth the Money?

Yes. Foam cannons and guns are used to help break up caked-on dirt without damaging the paint or protective coatings, which is something you would normally do by hand with a washing mitt or other manual tools. Even though foam cannons can’t get off every bit of dirt and you’ll still need a hand mitt to clean some spots, they can cut down on the time and effort needed to wash a car thoroughly. Even the heavy-duty ones aren’t that expensive, so if you wash or detail your car often, these tools will save you time and work and pay for themselves.

Downsides to Using a Foam Cannon

You can use your foam cannon every time you wash your car if you want to. This is just a guideline for when it doesn’t need to be done. Only because it wastes so much soap should you not use a foam cannon. If using it gives you benefits, then this is just a trade-off. But if you don’t need to use your foam cannon, you’re pouring soap down the drain. Depending on what kind of soap you buy, that can get pricey.

Foam cannons If you want thick, foamy suds, use a lot of soap. If you foam your car often, you’ll find that you use up your bottle of soap much faster. Adding an extra step to the way you wash will, of course, take more time. Even more so when you compare washing a car with two buckets and a garden hose to using a pressure washer and foam cannon.

Frequently Asked Questions (FAQs) about Foam Cannon

Is a foam cannon better than a foam gun?

Foam cannons are powered by pressure washers, so they will naturally make thicker foam and spray soap and water with more force than foam guns, which use garden hoses. Garden hoses use the water pressure in your home, which is not as strong as a compressor and may make the foam thinner or more watery. But a foam gun with a lighter touch might be better for most light jobs and cars with delicate or deteriorating finishes, like the metal flake paint on street cars from the 1970s.

Do foam cannons and guns speed up the car-washing process?

Absolutely. No other tool can spray as much soap on your car as a foam cannon, but foam guns come in a close second. Soapy lubricant helps loosen stuck-on dirt so it can fall off on its own. Overall, foam cannons and guns make washing cars faster by reducing the amount of work that needs to be done.

Is it worth buying a foam cannon?

Foam guns are worth it because the foam helps the soap stick to the surface longer, giving you more time to work before it dries or drips off your car. It also makes it easy to see where your microfiber wash mitt or brush has already been used.

How can I make a foam cannon foamier?

If you use more foam than you need, you will waste the product in the end. But if you shake the mixture of snow foam and water instead of stirring it, you will get more foam.

What is the point of a foam cannon?

A foam cannon is a piece of car washing equipment that mixes the right amount of car wash soap, water, and air to make thick suds, which are then shot all over your car by a pressure washer.

Do you need a pressure washer for a foam cannon?

Two things are needed to use a foam cannon: a pressure washer with enough power and water flow to run the cannon and chemicals that are made to be used with a foam cannon.

Do you get the car before foam cannon?

Rinse your car before you foam it to make it easier on your car and foam cannon. When you rinse your car, you get rid of the biggest pieces of dirt and debris so they don’t get rubbed into the paint.

Do all soaps work in a foam cannon?

At the end of the day, it doesn’t matter too much what car soap you use, as long as it is safe for clear coats. Some products, like Meguiar’s Hyper-wash, are made for foam cannons and guns because they make thicker suds and are usually more concentrated.
