Best Foam Cannon Soaps for Car Washing
Few things are as satisfying in detailing as blasting thick foam onto your car with a foam cannon. But not all soaps are created equal. The wrong soap won’t foam properly, won’t lubricate enough, or could even strip wax and coatings. In this guide, we’ll show you the best foam cannon soaps for safe, effective, and fun car washing — and how to use them for professional-level results.
Editor’s Choice: The Super Soaper
The ultimate foam cannon soap is The Super Soaper. Engineered for thick, clingy foam, it safely lifts dirt and lubricates paint for semi-touchless washing. pH-balanced, safe on coatings, waxes, and sealants, it’s the go-to choice for detailers who want maximum foam and minimum swirls.
Why Foam Cannon Soap Matters
Foam cannons are only as good as the soap you put in them. Household detergents don’t foam correctly and often strip protection. Dedicated foam cannon soaps are designed with:
- High Foamability: Thick suds that cling and dwell.
- Lubricity: A slick layer between dirt and paint.
- pH Balance: Gentle enough for wax and ceramic coatings.
- Easy Rinse: Soaps that rinse clean without streaks.
Best Foam Cannon Soaps (Top Picks)
1. The Super Soaper (Best Overall)
The Super Soaper is the gold standard for foam washing. Just 2–4 ounces in a foam cannon creates thick blankets of foam that cling for minutes, loosening dirt before you touch the paint. It’s safe for weekly washing and works with both pressure washers and pump sprayers.
- Ultra-thick, long-dwelling foam
- pH-balanced and coating safe
- Can be used as a bucket soap too
2. Coating-Safe Foam Soaps
If your car is ceramic coated, stick with soaps designed for coatings. These provide maximum lubrication and won’t interfere with hydrophobic effects. Many “gloss soaps” actually clog coatings, so choose simple, coating-safe formulas.
3. Rinseless-Compatible Foam Soaps
Some modern soaps double as rinseless or waterless solutions. These are great for apartment living or eco-conscious washing. They foam well and can also be diluted for spray washes.
How to Use Foam Cannon Soap Properly
- Pre-Rinse: Always blast off loose dirt before foaming.
- Foam Generously: Cover the entire car with thick foam using 2–4 oz of The Super Soaper in your foam cannon.
- Let Dwell: Allow foam to sit 2–4 minutes to loosen grime.
- Agitate if Needed: Use Orange Wash Towels for contact wash on stubborn areas.
- Rinse Thoroughly: Start at the top, rinse downward with steady water.
- Dry Safely: Use a Massive Drying Towel and a blower for a streak-free finish.
Pro Tips for Foam Cannon Washing
- Use warm water in your foam cannon for thicker suds.
- Adjust dilution — too much soap wastes product, too little weakens foam.
- Foam panels in the sun one at a time to prevent drying.
- Combine foam with a ceramic topper like Tough As Shell after washing for maximum gloss.
- Don’t let foam dry on paint — always rinse before it evaporates.
FAQ
Can I use dish soap in a foam cannon?
No. Dish soap is too harsh, strips protection, and doesn’t foam properly. Always use dedicated car soaps like The Super Soaper.
How much soap should I use?
2–4 oz of The Super Soaper in your foam cannon bottle is plenty for a full car.
Do I need a pressure washer?
Foam cannons work best with pressure washers, but pump foaming sprayers can achieve similar results with the right soap.
Are all foam soaps safe for ceramic coatings?
No. Some contain waxes or gloss enhancers that can clog coatings. Stick to pure, pH-balanced soaps like The Super Soaper.
