Foam Cannon Myths and Truths – What Really Works?
Not everything you hear about foam cannons is true. Let’s break down the myths and give you the facts to foam smarter—not harder.
Myth #1 – Thicker Foam = Cleaner Car
Thick foam looks cool, but it doesn’t always mean better cleaning power. What really matters is the chemical cleaning strength of the soap and how well it bonds with dirt.
The Super Soaper is formulated to create shaving cream-like foam that clings, lifts, and rinses easily.
It’s not just about looks—it’s about chemistry.
Myth #2 – You Need a High PSI Pressure Washer
You don’t need 3,000+ PSI to get good foam. In fact, many foam cannons work great with entry-level 1,500–2,000 PSI electric pressure washers.
The real key is the combination of GPM (gallons per minute) and a quality foam cannon like the MJJC or MTM.
Even a garden hose with the right adapter can work for lighter jobs.
Myth #3 – Let Foam Sit as Long as Possible
Letting foam dry on the surface causes streaks and water spots. Ideal dwell time is 2–5 minutes, depending on weather.

Myth #4 – Any Soap Works in a Foam Cannon
Technically, yes—but not all soaps are created equal. Dish soap or cheap car wash can strip protection or clog your foam cannon.

Myth #5 – Foam Is All You Need
Foam is step one. It pre-loosens dirt—but without a proper contact wash using a soft towel like the Orange Wash Microfiber, you won’t get a truly clean surface.
