How Do Foam Cannons Work?

In addition to making the vehicle washing process more enjoyable, foam cannons can also assist you in achieving excellent results when washing your vehicle. It is possible to use a pressure washer to spray creamy, shaving cream-like bubbles onto your car, which is easy to work with and remove. Furthermore, if you’re like the majority of people, you can use heavier foam with greater cleaning effectiveness.

How professionals use foam cannons?

The photos of automobiles soaked with thick, white shaving cream-like foam have piqued your interest, and you’ve pondered: “How precisely do they do that?” The secret is in the use of foam cannon! When it comes to car washing equipment, a foam cannon blends the ideal amount of vehicle wash soap, water, or air to produce thick suds, which are then shot all over your vehicle using the power of a water hose.

Foam Cannon For Car Wash

High-pressure washers are fantastic. A small electric and gas engine, powered by water from the garden hose, drives a pump that pumps water out at absurdly high pressures, allowing you to swim in it. Many different things can be done with them, but when they are connected to foam cannon, it shoots insane amounts of detergent that will turn any driveway into a winter wonderland!

Using a thick layer of foaming suds, lubricate the exterior of your car, enabling your cleaning mitt to glide over it without leaving swirls or scratches. Although either an electric or gas pressure washer can produce impressive suds, we have found that gas pressure washers consistently produce the best results.

How it works?

The way it works is as follows:

  • Fill the plastic container of foam cannon with 1 – 3 oz of your favorite soap and water and shake it up. Always use hot water because it aids in the aeration of the aerated mixture. Reattach the plastic container to the foam cannon’s head using the provided screws.
  • After filling the foam cannon canister with soap and water, easily fasten it to your washer’s lance and start spraying! Foam cannon are equipped with an adjustable dial, allowing you to fine-tune the amount of foam produced to match the level of dirt on the job. A wash setting for everyone, from the dirty off-roader to a gentle no-touch wash, is guaranteed to be found.

Generally speaking, it is preferred to apply a generous amount of suds to the vehicle and then wash it off before even getting our mitts dirty. All you have to do is coat your car with foam, allow it to sit for 5 minutes, and then let the sheer force of premium soaps and gravity do the rest.

Watch as that of the dirt & grime magically disappears from your vehicle. After that, just use water to clean the car. This simple step helps to reduce the likelihood of installing wash-induced scratches and swirls on your vehicle.

Now it’s time to get back to the fun part: foaming your car! One other overlay of slightly thicker car wash foam should be applied to your vehicle once more. You can even incorporate it into your game if you want! Just remember to utilize a cleaning mitt to scrub off any remaining dirt and grime after you’ve finished. Make use of the two-bucket method to further reduce the likelihood of swirls and scratches.

After you’ve finished scrubbing, make sure you rinse your car thoroughly to remove any remaining dirt or bubbles. Eventually, dry the car with such a super soft towel, just like you’d during any other car washing session.
