How To Use Cannon Soap?

Many of you might be thinking of the steps or procedures to use foam cannon soap. Well, it’s easy. All you need is to add soap to the cannon’s canister, expecting that you already have a gun performing. The point here to note is that you need to read the instructions on the product before using that, as some soaps are highly concentrated, so you need to dissolve them in water properly. In this way, that concentrated solution will not affect your car’s sealant.

What to Look for in a Foam Soap?

The key and essential thing to note while buying foam cannon soap is pH level. If the pH level is low, it means that soap is highly acidic, leaving more damage to the car’s paint. So, preferably you should look for soap having a pH level of 7. 

The subkey to note is foam’s thickness. Use a formula that is pointedly designed to be used as car soap because all of the car soaps are not thick enough to be used as foam cannons.

Tips And Tricks:

Here are some pro-tips and safety measures to make cannon soap with pressure washers more rapid, easy, and cautious.

Cannon Soap Application:

Never let cannon soap be dried. It doesn’t mean that you had to wash it off until the moment you have applied, but it defiantly also doesn’t mean that you should let it sit for a long time, till it gets dries. Rinse it off when you feel like this is the moment you should get rid of it or when it forms a foamy texture. Also, I will advise you to use it on some warm days, not too sunny or windy otherwise, and it will dry faster than usual.

The car should be rinsed with a pressure washer in the direction from bottom to up, and however, cannon soap should be applied on the top so that the foamy water can flow downward, cleaning all the parts.

To get better results and achieve maximum bubbles, you first need to rinse the car with lukewarm water. Next, if you have diluted cannon soap, it would be great to pour that into a bottle and gently revolve it using a microfiber towel. Otherwise, the bubbles will set themselves inside the bottle rather than being on the surface.

Safety Measures:

While working with pressure washers and cannon soaps, you need to wear some specific equipment to save yourself from any damage or harmful chemical. Necessarily, wear waterproof boots and clothes to protect your skin from making contact with any offensive material. Wear goggles to prevent eye and the area around as eye area is specifically sensitive. Wear breathing masks to save yourself from fumes of chemicals while breathing. Finally, wear plugs to hold hearing while performing with a pressure washer.

Be environment friendly and take care of your surrounding animals and plants; they should be kept away from the area where you are performing, as the chemicals used in soap can be harmful to them. Also, it would be best if you watered plants after using any detergent, vinyl, or product containing harmful material.

Buyers Guide:

Foam Forming:

The major thing to notice in foam cannon soap is foam. You require lots of foam, as it is mixing pressure from the cannon and the soap. This type of pre-cleaning is required. Regular soaps are unable to do this job as they are concentrated, and even when they are diluted with water, they still won’t be able to add sparkle like cannon soap.

pH Concentration:

note the pH concentration of the product. It is highly concentrated on level 0 and alkaline on level 14, and 7 is moderate. So, you have to keep an eye on neutral pH concentration as it will be effective to use and will never leave damage to the car.

Quick Dwell:

It is the time that how long will the product stay on the car before it is washed off. So quick dwell will be a plus point for you if you hurry and want to wind it up faster. But it is not preferred as it does not affect how good the job is. 


Many cannon soaps come with a good odor in different flavors like cherry, apple, and many others. You can go with any of your choices. It is helpful in case you want a good aroma after your product is being washed. You can also go with unscented ones if you don’t wish to adour.

Final Closure

All of the qualities we’ve discussed are worth examining, but in the end, the best option will be the one that produces the thickest foam and cleans the best, ideally with a pH close to 7.

Everything else is primarily “marketing fluff” and shouldn’t deter you from finding the highest-quality soap – since pre-washing with a foam cannon is the ideal way to help your car look its best.

Finally, many foams cannon brands advertise and attract you to use their product. But you are never bound to select their product. They may make terrific snow foam soaps, but you have to decide and choose the best product for you in terms of quality and quantity. Keep in mind that using cannon soap is essential as using shampoo while washing hair. So I have selected amazing products for you. If you can still determine, you can go with Chemical Guys CWS_402 Mr. Pink Foaming Car Wash Soap as this product is outstanding and will give excellent results. Still, if you have some questions, feel free to drop a comment or ask through the inbox. Thanks for reading.
