Why you should consider foam cannon

Foam cannons are a great replacement to traditional bucket and soap methods of washing cars. They are easy to use and save a lot of time. If you have a large, muddy car then you can relate with how frustrating it is getting it super clean.

Once you have covered the car in thick studs all you have to do is wait for the specially formulated studs to do its magic removing any grime or dirt from your car. You will then have to scrub the car gently so that you do not leave any scratches then a pressure washer will wash off the soap.

The foam cannon does a better job of protecting your car paint while keeping it clean than a bucket wash. All the products we have reviewed are biodegradable so you do not need to worry about them causing any harm to the environment. The solutions come with millions of active detergents that work on the dirt hence loosening it. This means you do not have to scrub the car surface aggressively.

Foam cannons are not relegated to car washes only, you can find an affordable device to use for your car at home.


For some people the only way to clean their car is through a bucket, soap and sponge. However, this can leave your car with numerous scratches hence destroying the paint work you have spent so much on. Foam cannons help create thick studs that loosen the dirt on your car. Once you have created the studs all you need to do is scrub your car gently then wash off the studs with a pressure washer.
