The Ultimate Guide to Foam Cannon Soaps – Best Picks, Techniques, and Pro Tips
Thick foam. Satisfying suds. Safer washes. If you're not getting these results from your foam cannon, the issue may not be your pressure washer—it’s probably your soap.
In this guide, we’ll break down everything you need to know about choosing and using the right foam cannon soap. Whether you're a DIY weekend washer or a seasoned detailer, this post will help you dial in your setup and results.
What Makes a Foam Cannon Soap “Good”?
The right soap does more than just foam—it lifts dirt, clings to paint, and rinses clean without residue. Look for:
- High foaming formulation
- Lubricity for safer contact washing
- pH-balanced and wax/ceramic safe
The Super Soaper checks all those boxes. It’s formulated to work with foam cannons AND pump sprayers, making it incredibly versatile.

How to Maximize Foam Thickness
Want that shaving cream effect? Here’s how to get it:
- Use 2–4 oz of The Super Soaper in your cannon bottle
- Top with warm water and shake well
- Set your foam cannon to max soap output
- Use a pressure washer with at least 1.5 GPM and 1,800 PSI
- Don’t pre-rinse unless the car is extremely hot or dusty
Then foam the entire car, let it dwell for 2–3 minutes, and rinse. For contact washing, re-foam and wipe down using a soft Orange Wash Microfiber Towel.
Can You Use Any Soap in a Foam Cannon?
Technically yes, but that doesn’t mean you should. Most store-bought car soaps aren’t designed to foam well or work in the dwell/rinse cycle of a touchless-style wash. If you want performance, go with a purpose-built soap like The Super Soaper.
Working in Direct Sunlight?
Foaming in the sun? No problem. You just need the right techniques:
- Set up all your gear before spraying
- Work on the shaded side of the vehicle first
- Foam → rinse → foam again — skip pre-rinsing unless the surface is hot to the touch
- Dry quickly using a Massive Drying Towel and blower
Finish with a light layer of Tough As Shell Ceramic Spray for protection and faster drying next time.
