Foam Cannon vs Foam Gun
It seems that the terms foam cannons vs foam guns are often used interchangeably. While this is sometimes accurate, there are other times when one or the other might define a product more directly. For starters, there is no question that there are benefits to using a foam cannon or a foam gun to wash your car or truck. While there may have once been uncertainty about whether using a foam gun was worth it, or why to use a foam cannon, it is typically accepted these days that regardless of the differences between a foam gun and a foam cannon, they are both considered a superior method for washing your truck or car.
If you are new to the world of foaming guns for car washing, or want to know more about foaming guns vs foaming cannons (or vice versa), you have come to the right place. First and foremost, it’s important to note that there’s no doubt that using a foam gun to wash your car or truck is the fastest way to get the job done. Not only is it super satisfying to coat your vehicle with a thick layer of suds, but those thick suds have lots of benefits!
Foam guns are worth it because foam helps the soap cling to the surface longer, giving you more working time before it dries or drips off of your vehicle. It also helps you see clearly where you’ve already scrubbed with your microfiber wash mitt or brush. But there is more to know when it comes to foam guns vs foam cannons, and if you're looking for a brushless car wash solution, the truth about that process may surprise you. We're going to cover it all! Let’s dive into the difference between foam guns and foam cannons, plus how effective each option is for your situation!
WHAT IS THE DIFFERENCE BETWEEN A FOAM GUN AND A FOAM CANNON?
Let’s start with the basic question to get this kicked off—Is there a difference between a foam cannon and a foam gun? And if so, which one is right for my situation? Why use a foam cannon as opposed to a foam gun for washing my car? While it might seem like an obvious question with a cut and dry answer, it is worth breaking down further. For starters, both foam cannons and foam guns serve the same basic purpose; to efficiently coat the exterior of your vehicle with thick, sudsy goodness with high lubricity truck wash soap without the need for buckets. Sounds appealing, right? But again, since foam guns and foam cannons accomplish the same goal, how do you decide which is the best option for your wash needs?
Let’s break foam guns vs foam cannons down a bit further and help you decide what makes sense for you.
PRESSURE WASHER FOAM CANNONS & GARDEN HOSE FOAM CANNONS
You might be wondering if there is a right time to use foam cannons vs foam guns. Let’s start with some of the benefits of foam cannons. Foam cannons these days are made to be very sturdy and designed to be used over and over. Foam cannons for garden hose setups have become very reliable for people without a pressure washer. However, the best pressure washer foam cannons output way thicker foam than any garden hose foamer ever could.
For the average person washing their car or washing a semi-truck, foam cannons are going to be the best option. The benefits of foam cannons are that they are both affordable and reliable options for any DIY car wash enthusiasts. The portability of foam cannons also makes them a good option for individuals without a permanent wash setup.
However, this is not necessarily the case for a professional with a garage that sees many vehicles on a daily basis. For professional detailers who wash a lot of vehicles, the foam gun is worth it, and likely a better option overall if the goal is to maximize profits by reducing the time it takes to complete a wash job. Essentially, if speed and profit are the name of the game, then using a foam gun to wash the cars is likely the right move.
Some websites (including ours) refer to pressure washer foam cannons as foam guns. In these instances, they mean the same thing. Kind of like calling a pressure washer a power washer. Or Fork Lift vs Hi-Lo. It’s just a regional difference in the term you use to describe it.
However, that is not to say that there are zero differences between foam cannons and foam guns. We have already established speed in a professional garage, as opposed to DIY home washing. But differences between foam cannons vs foam guns don’t stop there.
Here at Image, we actually have real foam guns as well. If you're serious about your wash game, keep reading.
FOAM GUNS & LANCES - THE PROFESSIONAL OPTION FOR FOAM WASHES
There are certainly other times when foam guns for washing cars is the best option to go with. These foam guns are used by commercial truck washes, fleet washers, and professional detailers. Heavy duty industrial strength foam guns are designed to be used with pressure washers and replace foam cannons all together. These foam guns are used with downstream injectors to pump your favorite truck wash soap and other chemicals straight from the bottle, through your pressure washer hose, and then turned into super thick suds at the foam head connected to your trigger sprayer.
Here are the two best options for professional foam guns.
DOUBLE BARREL ALL-IN-ONE FOAM GUN WITH RINSE BARREL
Dual barrel pressure washer guns, like our Foaminator, are the best for maximizing efficiency and reducing wasted time. They also help to ensure consistent chemical dilution, so you always know you have the right ratio of soap to water. With less chemicals being wasted by “eyeballing it” to fill up soap canisters, you increase profits for your business.
Since the Foaminator includes a foam barrel and a separate rinse barrel in one gun, there’s no need to constantly swap quick connect barrels or rinse tips. The top barrel has a foam head at the end which produces thick shaving cream type foam. In the middle of the gun, there’s a changeover valve that changes the gun functionality from the foam barrel to the rinse barrel with a simple quarter turn. This changes the suction pressure in your hose which stops the injector from being able to pull soap, allowing you to rinse from the bottom barrel without any additional steps.
“But what if I need to foam more than one chemical?”
That is certainly a fair question, and one that we can definitely answer. Simply put, the Foaminator works with all sorts of injectors. We offer them with a single injector (for use with one chemical at a time) or a dual injector that has a physical handle to choose which soap you want to pump through your foam gun. For truck wash bays that often use more than two chemicals to wash equipment, we also custom build injector boxes with multiple soap options. They include light-up push buttons to indicate which chemical you want to foam, with separate lines running from each chemical barrel or tote. If you were using 4 chemicals to wash dozens of trucks per day, you wouldn’t want to stop to fill up four separate foam cannons. That would be a massive waste of time. When it comes to commercial truck wash bays, time is money!
PISTOL PETE - PROFESSIONAL FOAM GUN
This is the best foam gun for washing cars for professionals looking for a less bulky option. This style of foam gun comes with a quick connect socket that you can attach a foam head to and then swap it for your rinse barrel when you’re ready to wash off the foam. Since the foam head on the Pistol Pete is the same one as the Foaminator, you still get the same thick suds. Our Pistol Pete foam gun can be used with single injectors, dual injectors, or custom injector boxes with 3+ chemical options.
DO YOU HAND WASH AFTER FOAM CANNON?
This is where the biggest misconceptions come from. Regardless of whether you are using a foaming gun vs a foaming cannon, neither product should replace using a wash mitt or brush. However, washing with foam can (in some cases) eliminate the need for hand washing. A lot of factors come into play here, so let’s break down some different scenarios. If you're looking for the best foam cannon car wash experience, here's what you need to know.
WHEN YOU SHOULD HAND WASH
If your goal is to wash your truck 100% clean with no road grime leftover, it’s time to hand wash. After foaming on your favorite truck wash soap, use your wash mitt to gently agitate the soap. Besides being super concentrated, truck wash soaps like our Platinum Wash or Wash & Wax are perfect for hand washing since they have a neutral pH and contain lubricants that gently encapsulate the dirt particles to prevent scratches to your paint’s clear coat as your mitt glides across the paint.
For very lightly soiled vehicles, you can sometimes get away with using these same soaps without a brush. This would mainly be an option for people who wash their vehicle multiple times per week or for vehicles with ceramic coatings.
TOUCHLESS OR BRUSHLESS CAR WASH
Touchless washes are a great option for a few different situations, but they do require different chemicals. Brushless truck wash soaps are a 2 step process. You start by foaming the first soap, a low pH acid, onto the vehicle surface. This pre-soak neutralizes the positively charged particles stuck to the surface. Once the first step has sat for a minute or two, you then foam the second soap over top of the first step. The second soap is a high alkaline soap with degreasing properties. That high pH neutralizes the first soap and negatively charged dirt particles, resulting in a neutral pH mixture on your surface. The chemical reaction between these two soaps breaks the static bond that makes dirt stick to your surface, so you can easily pressure wash it clean without a brush or mitt.
If your vehicle has a wax or ceramic coating, you can expect touchless soaps to get your vehicle 100% clean or very close to it depending on how well you rinsed.
If your vehicle doesn’t have any protective coating, but you keep up on weekly or bi-weekly hand washes, you can expect the brushless soaps to get your equipment about 90% clean with only a thin layer of road film left behind.
If you prefer to wash once a month and your vehicle doesn’t have a protective coating, we would recommend hand washing for the best results.
