How This Foam Gun is a Great Substitute for a Pressure Washer

When it comes to washing my car, I prefer using a pressure washer, but I'm well aware that isn't feasible for everybody. One of the main reasons why I enjoy using a pressure washer is because of the foam cannon, which blankets my car with a nice layer of soapy car wash. But if you aren't able to use a pressure washer with a foam cannon, the Foam Blaster 6 from Chemical Guys is a great alternative.

Chemical Guys sent me the Foam Blaster 6 so I could compare its performance with using a pressure washer and a foam cannon. It's the ideal product for those who use a garden hose when washing their car. The product comes with a powerful hose nozzle that's compact and lightweight, making it comfortable to use. At the end of the nozzle is a quick connect for you to easily attach the foam gun. The process is simple: use the hose nozzle to rinse off any loose dirt and sediment off your vehicle, then attach the foam gun and give your vehicle a nice coat of car wash soap. When you're done washing, simply disconnect the foam gun from the nozzle and rinse off your car.

For those who have used Chemical Guys products in the past, you know what to expect with the brand. They have built a solid reputation of offering quality car detailing supplies at a competitive price. The Foam Blaster 6 is no different with its premium construction. In my experience, one of the biggest issues with foam cannons is a weak neck, which causes the bottle to break. You won't have to worry about that here, as everything is properly supported. As you can tell from my photo, I can easily use this with one hand. The foam gun also makes it easy to apply some foam directly onto your wash mitt before you start wiping down your car.

It may seem like a minor detail, but one feature I really love about the Foam Gun 6 is the line designating how much soap to use. Instead of having to measure out one, two, or three ounces—whatever your car wash soap calls for—you simply fill the container up to the line with your favorite car wash soap, and then fill the rest of it with warm water. Now, some highly concentrated car wash soaps may require a different mixture, but if you're using a soap like Chemical Guys' Mr. Pink (which is my personal favorite), then you're all set using the guideline on the bottle. It's little details like this that leads me to believe the folks behind Chemical Guys' products are car enthusiasts who use their own products.

Naturally, using this foam gun won't produce the same amount of suds you'd get using a pressure washer and a foam cannon, but the results were even a bit of a surprise for me. You can control the amount of suds you want depending on how dirty your car is. If your car isn't very dirty, you can save both water and soap by turning the dial and adjusting the dilution ratio. Personally, I believe the more bubbles the better, as it gives you a real slick surface to wash.


You're probably asking, why do you need a foam gun? Why can't you just use the proven method of mixing car wash soap with water and applying it with a mitt? Well, for starters, blanketing your entire car with a layer of foamy soap helps prevent possible scratches while you're washing your car. It also reduces the amount of time you need to spend dipping your mitt back into your car wash bucket. When you're spraying that mix of soap and water onto your vehicle, you're also getting rid of loose dirt without applying any pressure. The first time you use a foam gun or a foam cannon, you'll notice the difference right away. Washing your car takes a lot less time and effort, but more importantly, you get better results.

    I often come home late so it's difficult to find a place to wash my car
