Difference Between Foam Guns And Foam Cannons 

If you are not well aware of all the positive and negative aspects of both the foam guns and foam cannon. You will always feel difficulty choosing between the cannon car wash or the foam gun. 

Though both hold their distinctive characteristics and serve a great deal when it comes to cleaning your car. But using them in accordance with the scenario and the type of vehicle can bring out better results. Let us tell you the difference between both these car washing equipment with their usage. Read More.

Foam Guns 

The guns are the extensions that are used to connect to the garden hose and they are used for traditional car cleaning methods. Though the best foam gun without pressure washer and the foam cannon serve the same purpose they differ because of the consistency of the foam they produce. 

As the typical foam guns are mostly attached with the garden hose yet they receive less pressurised water. That does not mix the perfect amount of air to create the thick foam hence resulting in runny foam. That will not be clingy to the surface of your car and will run down within no time. Hence it might not remove all that stubborn dirt from the surface of your car. 

Our expert considers that purchasing a foam gun without a pressure washer is a total waste of money. Instead, you can go for some pressurized water sprayer to get better results in such a scenario. 

Foam Cannons 

The best snow foam cannon and foam lances are attachments to the pressure washer. The most reliable aspect about them is that you can easily attach them with any pressure washer and enjoy amazingly thick foam. 

The foam cannons for hoses are mostly preferred by car enthusiasts as they offer ease of cleaning. The pressure washer offers pressurized water that is ideal for better mixing of the soap and air. And hence it will spray out a thick foam that will stick to your car surface longer to eliminate all kinds of dirt and grime. 

Things To Know Beforehand 

There are a few factors like the preflight checklist that you should confirm before making any move. This will ensure how smoothly your car cleaning procedure will go and you will eliminate all the chances of any possible accident.

Type Of Your Pressure Washer 

It’s vital to know the type, brand, and build of your pressure washer beforehand. As all of them hold their distinctive features and come with different cleaning options. 

The two basic types of pressure washers are one electric-powered and the other gas-powered. Though both of them are effective and do their job nicely, the gas-powered pressure washers are mostly preferred by the purchasers. 

Though we have used both of them, personally we will also suggest you get the gas-powered washer. As it offers higher GPM (Gallons Per Minute) and the PSI (Pounds Per Square Inch) which is associated with thicker foam. 

Experts suggest that you should get pressure washers that offer 1.75 GPM and 1900 PSI ratings if you seek perfection and ease with your car washing. 

Type Of Your Foam Cannon

Before you question how to wash a car with a foam cannon you should try your best to know the brand and type of the foam lances you purchase. Though there are numerous choices available in the market and the best one to go for is that fits your budget. 

But it’s better to purchase an expensive one than the cheap one because of the build quality. Also, this can be a pretty good investment as they will last longer and you will not have to purchase one often.

Go for the foam cannons with the brass connectors with multiple nozzles and knob adjustments. So you can enjoy more spraying patterns and also look for the soap control knob to adjust the consistency of the soap. You can adjust the knob to have the thickest clingy foam and also to get the runny watery foam.

Though having more adjustment options can enhance complexity, you can avail of simpler ones as per your choice. 

Water You Are Using 

The factor that you might not be aware of is that the water you use can also affect the consistency of your foam. As if you are using tap water you might not get your desired results as the tap water is considered hard water because of its high minerals. 

These minerals fight with the active ingredients of the detergent and make them less effective while you might also get to witness some watermarks over the surface of your car. 

Hence it is suggested to use foam cannons for the hose as the filter of the hose will have cleaner water to offer. In contrast, for the best results and maximum thickness of the soap use distilled water as it does not contain any minerals. 

Maintenance & Storage Of Your Foam Cannon 

If you do not take care of your foam cannons in between washes it can result in breakdowns you might witness the build-up of calcium deposits. So if you do not want to waste your money on frequent purchases of foam cannons. 

Make sure to maintain them nicely and the best you can do is to properly clean your foam cannons after every use. Do not leave any traces of the water and the car washing shampoo inside the container. 

Also, wash the foam cannon with water and spray clean water once or twice to eliminate any soap from the nozzle or the suction tube. Then air-dry your cannon to eliminate any chances of rust and other factors. You can then store them at some cool and dry place until the next use.
