Here are a few pointers to help you with selecting which is going to be the best option for you, depending on your needs but also a few other tips which you may find useful:

For washing a car with a foam gun, you follow much the same steps as you would if you were doing it the old fashioned way - rinse the initial dust and dirt off with clear water, do a shampoo wash to break down grease, stubborn marks and dirt remaining and then rinse off with clear water, dry off and polish.  

You can use the nozzles/lance that come with your foam gun to help with the initial rinse down, as they can give you more direction and power, especially useful for the wheel areas.  

Then you load up your foam container and attach the nozzle/lance.  When first using, it is good to check and test the various settings to see what gives you the best coverage of foam and sufficient pressure to apply it but not to blast soap all over you and the neighborhood. 

You want to allow the foam to sit on the car to allow the detergents to get to work, breaking down the dirt.  So, you don’t want your mix too watery and you need volume of bubbles which make take a few attempts to find which settings give you this.

Starting from the top horizontal surfaces (roof), start applying the foam, working your way down the sides and then to the skirting and finally the wheel arches and wheels.

Once you have coated the car fully in foam, do allow it to sit for a short while to let it have time to work on breaking down the dirt etc.  Don’t let the foam dry on the car (that is not good and will only give you more work to do).  

The foam will naturally start to slide off and of course that is helping you as it takes the dirt with it.  After about five minutes the majority of the foam will have worked its way off and now you can rinse off the rest with clean water. 

Once fully rinsed you can dry and polish the car and check out your image in that squeaky clean reflection.

When you are looking to invest in a foam gun for washing your car you will also find the word cannon or blaster coming up in your searches so what is the difference.  

Primarily as the words would imply - a gun is going to be less powerful than a cannon/blaster) and it isn’t a case of more powerful is always better, it may be that you don’t need such a powerful tool, so it would be a waste of your money to go for a foam cannon option which is likely to cost you more.

The other thing you have to aware of is that for a foam cannon product is going to need to work with a pressure washer to work adequately, because it is more powerful, you need to have something to create that additional power and so you will see information advising you that to operate it you will have a minimum requirement of pressure and water flow, on the other hand a foam gun or sprayer can be used with you normal hosepipe.

A foam gun is more than adequate if you want to have the benefit of producing a good constant application of foam to your car to shift a general build up of dirt. 

It is also a better option to use if your car is an older model, with some delicate materials or additions that you don’t want displaced or damaged by ‘blasting’ it with super-charged suds, the job may get done quickly, but how much extra time do you then need to invest to repair any damage you may have created?

Using a Foam cannon comes into its own if you have tougher, off road vehicles that can take and probably require a heavier handed approach to get through the mud and grime they regularly collect.

Also, if you have a large number of vehicles to turn around in a quick time the cannon will help you speed through them but do watch out for that extra power you have and what you do with it. 

Using a foam wash gun to clean your car is going to give you a much better and quicker overall wash than you can achieve manually.  

With many of the foam wash guns now available you can use a simple dial to get the right mix of foam solution to water and air to create the right type of foam to give good even coverage which then sits on the surface of the car, breaking down and loosening all the dust and debris that has gathered, hence enabling you to easily remove the dirt from every corner and without as much physical exertion. 

It is great when you can get a professional car wash done but cost and availability may mean this isn’t always possible; your favorite car wash and detail company may be some distance and always busy so when you need an urgent clean up it is quicker and easier to get it done on your own drive. 

But also, if you do need to have a weekly wash then that cost can add up, so this is where using the foam gun for car wash comes into play; you have the convenience of having the equipment like the professionals to hand, doing it yourself is a big cost saving and you have the satisfaction of a job well done of your own doing.  

Another bonus of taking on the cleaning yourself is getting to know your car better and spotting any problems or niggles that it is good to get sorted as soon as possible.  Getting up close and personal with the paint work means you spot those scratches or knocks that can do with being treated to prevent rust setting in. 

Or doing the detail on the wheels on a regular basis means you are far more likely to spot if the tread is getting low, or if the pressure needs adjusting.  It is like your own body, the more familiar you get with how it should look when it is performing at its best then the same goes for your vehicle.  

If something is not quite right, the sooner it is corrected the less chance there is of it failing on you at the worst possible moment or perhaps creating other problems which take more fixing and are costly.

We do of course have to talk about any downsides to using a foam gun or cannon to wash your car, just so you are aware.  The main cons concern safety because you are working with chemicals and in some instances, high air pressure both of which need to be handled with care. 

It goes without saying, but I just to be sure - you should always fully read the instructions on the shampoo and foam solutions, as well as the usual warning about keeping it out of your eyes and it being an irritant to skin in neat form, do take note of the dilution tables, especially if using a concentrated product.

Not only will too much of the solution cause too much foam (yes, you can have too much) but also, if you are regularly using too strong a solution on your car, it can cause any finishes to deteriorate quicker and your paintwork to dull.

So, once you have purchased the best foam gun for cars, whether it is the basic trigger and car foam or have gone for the full kit which literally has everything - Gun, cloths, wire brush, detail spray etc.

You now know that the finish you get is as good as any professional car wash, was far quicker and easier to achieve than using your old garden hose and cloth and just possibly will tempt you tempted to hunt out those muddy roads or park under a line of trees just so you have an excuse to test out your new toy and skills!
