How I picked and tested foam cannon soap
I evaluated the product details, online reviews, and customer feedback when compiling this list of the top car wash foams. Then I decided to devote a few days to meticulous testing of the selected solutions myself!
With each soap, I did the following:
- Rinsed my auto
- Added 1.5 oz of the soap to a 1l-bottle
- Applied the solution to the car
- Left it for 5 min
- Rinsed the car
- Wrote data in the table
- Compared the results
I used each soap for a dark-colored vehicle to see the results clearly and mostly did the side panels to check how well the foam sticks. Then, when it was time to choose the winner, I paid close attention to the soap’s overall effectiveness (how well it restores the surface appearance), the convenience of use, and the price-quality ratio. See my champions below!

Foam cannon car wash buying guide
Soap designed for foam guns
Foam cannons work best when used with a soap designed explicitly for foam guns. This type of soap is formulated to create a thick, clinging foam that can be easily rinsed away. Unfortunately, standard car wash soaps are not always effective in a foam cannon, so it is essential to use a specifically made soap for this purpose.
There are many different brands and formulations of car soap for foam cannon, so it is important to do some research before purchasing one. Some of the more popular brands include Chemical Guys, Adam’s Polishes, Meguiar’s, and Sun Joe. These soaps effectively create a thick foam, safe for use on all types of vehicles, and some of them are also biodegradable.
When using a foam cannon, following the manufacturer’s instructions is important. Be sure to use the correct ratio of soap to water and test the foam on a hidden area of the vehicle before beginning the entire wash. If the foam is too strong, it can damage the paint or strip the wax. But if it is used correctly, a foam cannon can be a great way to clean your car.
Cleaning and foaming ability
When looking for a car wash soap to use in your foam cannon, it’s essential to consider its cleaning and foaming ability. Some soaps are better at removing dirt and grime from your car’s surface, while others produce more foam.
Choosing a soap that excels in both areas is the way to go, but if you have to choose one, opt for a soap that cleans well. For example, a good foaming car wash soap will still clean your car’s surface, even if it doesn’t produce much foam.
By the way, a higher price doesn’t mean that the solution works better. The price tag mostly depends on the size of the bottle. Note that buying a smaller container is an excellent method to assess if the soap fits your expectations, and you don’t have to spend a lot of money to find out whether it’s good for you.
Balanced pH formula
You may remember learning about pH in high school science lessons. Simply put, pH is a measurement used by scientists to determine how acidic or alkaline a substance is.
A pH of 0 is completely acidic, whereas a pH of 14 is completely alkaline. The pH-neutral number 7 is the sweet spot for car soaps. That means it won’t affect your car’s protective layer, such as wax or sealer. It also won’t affect your auto’s other components, e.g., a plastic trim. pH neutral solutions are made to keep your paint from peeling or fading.
Although most foam soaps for cars are pH-neutral, it’s a good idea to double-check the specifications before buying.
