Car Wash Soap For Foam Cannon

Dedicated vs Versatile Formula

Both the Chemical Guys and Adam’s Polishes formula have been designed primarily for foam cannons. This means hundreds of hours of research and development along with thorough testing has taken place before it has gone on the market.

These will be the best option to choose if you want thick suds but often come with a premium price tag. Alternatively you may already have a car wash soap that is suitable for use with your foam cannon already. There are only a few that have the ability to be used within a foam cannon and this will be stated upon the bottle.

If you want to keep costs down and don’t want multiple containers hanging around, then a versatile formula is perfect. However, for an effective washing solution that is able to produce seriously thick suds, the dedicated formula are best.

pH Neutral

You have probably seen that most brands will clearly state that their formula is pH neutral. In short, this basically means that on the pH Scale, which is between 0 for acidic and 14 for alkaline, the soap is a pH of 7, which is classed as a neutral solution.

The importance of a pH neutral formula is that it will not strip any wax or sealant that has been applied to your paintwork. It will also not cause fading of plastics or other automotive surfaces, which can be a common problem.

How To Use The Soap

Depending on the foam cannon soap that you choose, you may be required to dilute the solution. This will be stated upon the usage instructions upon the bottle. However, if you want to produce extremely thick foam, you can make the formula more concentrated.

With the correct diluted formula, you can then fill the reservoir and begin to cover the vehicle with as much foam as you wish.


Using a foam cannon is not only an effective method of cleaning your car but also great fun. Using the best soap for foam cannons will allow you to produce millions of thick suds that is safe to use and will not strip any wax or sealant.

Our recommendations cover a range of different soaps that include those dedicated to foam cannons and others that are more versatile. We highly recommend formulas that are dedicated for cannons but from an affordability perspective, the versatile formulas are still an excellent option.
