If you are a car enthusiast, then you need to invest in a foam cannon and soap. Foam cannons make the process of car washing much easier and more fun by shooting thick foam over your car, which gently lifts away dust, dirt, and grime. That said, to get the perfect foam consistency, you need to use the right soap.

In this post, we’ll review the best foam cannon soap of 2023. We’ll discuss what makes each one of these soaps special and why they are suitable for your car washing needs. We’ll also discuss the factors to consider when buying foam cannon soap and some of the common mistakes people make while using it. Read on to find the perfect soap for your foam cannon!

Buying Guide: Foam Cannon Soap

Choosing the finest foam cannon soaps can be challenging with so many soaps on the market. With the aid of this guide, you will be able to browse the various foam cannon soap varieties on the market, comprehend their features, and ultimately decide on the right one to purchase.

Factors to Consider 

Foaming and lathering ability

Foam cannon soap's capacity to foam and lather is crucial since it directly impacts how well soap cleans. The active components in soap will have enough time to break down dirt, grime, and other contaminants if they are designed to produce a thick, soapy foam that sticks to the surface being cleaned. The foam further aids in the releasing and lifting of dirt flecks from surfaces, making it easier to rinse them away. When looking for a foam cannon soap, it's crucial to consider how well it foams and lathers because doing so helps to lubricate the surface being cleaned and lowers the possibility of scratches or other damage.

Compatibility with pressure washers

It is crucial to ensure the foam cannon soap you choose is compatible with the pressure washer and foam cannon attachment you intend to use.  I recommend checking the manufacturer's recommendations before making a purchase of all three of these items to know if they synergize. I personally don't want to buy items and regret my purchases afterward when I find out they don't work together. The majority of foam cannon soaps are compatible with foam cannon attachments and a wide range of pressure washers, usually up to 3000 psi or more.

Soap concentration 

The concentration of foam cannon soap is important because it affects the foam's quality and the soap's cleaning ability. A foam produced by highly concentrated soap is thicker, more stable, and better equipped to lift and remove impurities. It also extends the life of the soap by allowing it to be diluted with water. On the other hand, a foam made with low soap concentration is less dense, requires more physical volume to be useful, and is less likely to be effective. I would pick a foam cannon soap with a high concentration for optimal cleaning results and value. I also caution people not to use too much highly concentrated soap, since you don't need to much for it to be effective.

pH level 

The pH of foam cannon soap is crucial since it can impact the soap's cleaning capacity and safety when applied to your car's surfaces. Too high or too low a pH level might improve cleaning power but harm your car's paint, trim, or other delicate surfaces. Look for a foam cannon soap with a neutral pH level, ideally around 7, as most automotive surfaces, such as paint, plastic, and rubber, are safe at this level.

Environmental friendliness 

While looking for foam cannon soap, take into account its influence on the environment, including biodegradability, recyclable packaging, and non-toxic components used in production. Although eco-friendly products can be more expensive, they provide superior value over time since natural components are gentler on surfaces and ecosystems than synthetic equivalents. 

Ability to remove tough stains 

When shopping for a foam cannon soap, it's essential to consider its ability to remove tough stains, such as mud or oil spills (if you deal with one type of stain often, I would focus your search on that type of stain remover).  Look for soaps with active agents, such as bleaching agents, that can dissolve hard-to-remove stains without damaging delicate surfaces like paint or chrome trimming. Stronger formulas might be better at getting rid of tough stains, but they might also wear down materials because of their higher active agent concentrations.
