How to Get Thick Foam From Your Foam Cannon (Pro Tips)
Struggling to get thick foam from your foam cannon? Here’s how to dial in your setup and soap choice to get the thickest, safest foam for your car.
Why Thick Foam Matters
Thick foam isn’t just for looks. It:
- Helps loosen and encapsulate dirt before your wash mitt touches the paint
- Gives better dwell time for safe pre-cleaning
- Makes your wash faster and safer
How to Get Thick Foam
1. Use the Right Soap
Not all soaps foam the same. Many soaps marketed as "car wash soap" won’t foam well in a cannon. You need a true foam cannon soap like The Super Soaper.
- Formulated to create thick foam
- Safe for ceramic coatings, PPF, and wax
- Works in both foam cannon and bucket

2. Dial In Your Dilution Ratio
The right soap dilution is key. For The Super Soaper we recommend:
- Foam Cannon: 2-4 ounces of soap + rest water (adjust based on your cannon and water hardness)
- Pump Sprayer: 1-2 ounces per liter of water
3. Use Quality Equipment
- Foam Cannon: Use a reputable cannon with an adjustable nozzle (MJJC, MTM, etc.)
- Pressure Washer: 1200-2000 PSI is ideal for consumer setups
- Garden hose foam guns can work but won’t produce "shaving cream" level foam
4. Water Quality Matters
Hard water can kill foam. If possible, use softened or filtered water to maximize foam thickness.
5. Adjust Your Technique
- Fill cannon with correct dilution
- Turn air mix down for thicker foam
- Spray from the bottom up for best coverage
- Let dwell 3-5 minutes, then rinse and proceed with your contact wash
Common Mistakes That Kill Foam
- Using the wrong soap (regular car wash soap won’t foam thick)
- Wrong dilution — too much or too little soap
- Dirty foam cannon filter or orifice
- Hard water supply
- Weak pressure washer
