The Best Foam Cannons for Car Washing

Car washing just isn't part of our regular cleaning schedule. After all, it's grueling work lugging the bucket around as we toil to soap up every inch of our vehicles, especially in bad weather when our cars need a touch-up the most. Thankfully, there's a handy little tool called a foam cannon that may actually make your car cleaning experience pleasurable. Simply attach one to your pressure washer (or in some cases, even a garden hose) and spray away. You may be surprised at how easily you can spread soapy foam all over your vehicle with the right foam cannon. Here, we've rounded up our favorite foam cannons to make sure you always have a clean getaway.

Frequently Asked Questions

How do I use a foam cannon?

Gently rinse down your vehicle with water to remove any obvious pieces of dirt. Then, fill your soap lance tank with warm water and then add 1 to 3 ounces of your preferred car wash soap. Attach your foam cannon to a compatible pressure washer and spray down your car from top to bottom. Let the foam sit there for the recommended time and then rinse the car with your pressure washer, using a soft sponge to further wash it if you wish.

What can I adjust when using a foam cannon?

Most foam cannons come with adjustable air/water intake dials and spray fan nozzles. The former lets you choose the thickness of the foam. By reducing the water and increasing the air, you’ll get a thicker soap. The latter lets you change the fan of the spray. We typically use the wider fan to cover the whole car evenly and then the narrow fan for more detailed areas near the tires.

What kind of soap should I use?

You should only use car wash soap in a foam cannon. These are highly concentrated and have high ‘suds’ capabilities, resulting in the thick foam we all know and love.
