Instructions For a Foam Cannon Jeep Wash

By following the next series of steps, you will be able to clean your Jeep using the foam cannon method.

Step 1 – Fill the foam cannon to the 200 mL mark.

Pour in soap

Step 2 – Fill the foam cannon bottle with warm water mixing the soap with the warm water.

Step 3 – Attach the foam cannon to the gas or electric pressure washer.  The pressure washer MUST be rated at about 2 gallons per minute. 

Step 4 – As you prepare to begin spraying, adjust the volume of soap dial on the top of the foam cannon, and the nozzle of the foam cannon to give you the desired amount of foam and spray angle.

Step 5 – Begin spraying on the Jeep while it is dry.  This allows the soapy foam to cling to the dirt, loosen it, and begin to drip it down the side of the Jeep to the ground.  Do NOT allow the soap to dry.  If the Jeep wasn’t too dirty to start with, you can begin to rinse the Jeep after a couple of minutes of soaking.  If it was exceptionally dirty, you may elect to repeat the wash and rinse cycle two or three times, or just add repeated coats of soapy foam to allow it to soften and remove the dirt over more time.

Step 6 – While you give the soap time to soak into the dirt and run off, I sometimes remove the tough spots, and bugs on the grill and windshield using a microfibre wash mitt.

Step 7 – After you’re satisfied with the amount of soaking of the foam on the dirt, remove the foam cannon from the pressure washer and rinse off the Jeep with just water.

Step 8 – Further drying and detailing instructions can be found in the bucket wash method article and video, but for the most part, you have just easily and quickly washed your Jeep with a foam cannon.

How to Get the Material You Need

Below are instructions on how to get what you need, and how you can get it, inexpensively. Links to products mentioned in the article are also found on the websites Featured Products page.

Foam Cannon –

Professional quality foam cannons can run upwards of $200.  The one I used in this article and video, was a budget brand, Amazon acquisition that cost under $30 (CDN) I was satisfied with its performance and quality, and recommend getting one of these foam cannons for the average Jeep lover trying to have fun looking after your Jeep.

Car Wash Soap –

Reviews online rate different soaps for their performance in a foam cannon.  The soap I used, as was evident in the article and video, worked very well in the budget brand foam cannon, and would use it again.  Some other soaps received good reviews online, but I haven’t tried them yet.

Pressure Washer –

Whatever pressure washer you use, it should be capable of spraying about 2 gallons per minute in order to produce adequate foam action.  

The pressure washer featured on the “Featured Products Page” has received good reviews from people using the foam cannons, and is likely the one I’d get if I didn’t already have a capable pressure washer.

Pressure washers that function at this capacity aren’t cheap, and some people already have pressure washers that do not meet this criteria.  For those people, some folks on the forums have shared that by replacing the orifice in the foam cannon with one that has a hole size of 1.1mm, they have been successful at producing foam from the cannon with their existing pressure washer.

So it isn’t necessary to spend upwards of $200 on a pro level foam cannon, when as evident in this article and video, a budget brand foam cannon can still function well enough to do the job of washing your Jeep. The foam cannon is a quick and easy way to clean your Jeep, and now that we’ve learned it can be done relatively cheaply. Therefore, we can now use the extra time and money that we’ve saved to ponder what else we can now buy for our Jeeps.
