How to Mix Car Wash Soap for Foam Cannon or Pump Sprayer
Getting thick foam isn't just about the cannon—it’s about the mix. Here’s how to properly dilute your car wash soap for foam performance without wasting product.
Why Mixing Soap Matters
Too much soap wastes product. Too little creates watery foam that slides off too fast. The right soap-to-water ratio gives you thick, effective foam while saving money.
Best Soap for Maximum Foam
The Super Soaper is designed specifically for both foam cannons and pump sprayers. It’s hyper-concentrated and creates thick, shaving-cream-like foam with the right dilution.
Foam Cannon Soap Mix Ratio
- Water Tank Size: 32 oz standard cannon bottle
- Recommended Mix: 4 oz of The Super Soaper + 28 oz water
- Pro Tip: Warm water helps it mix better and foam thicker
Pump Sprayer Soap Mix Ratio
- Water Tank Size: 1 liter (or 34 oz)
- Recommended Mix: 2 oz of The Super Soaper + fill rest with water
- Pro Tip: Shake well before pressurizing
Why Foam Matters
Thick foam clings to the surface longer, lifts dirt safely, and lubricates your wash. It reduces the chance of scratching during the contact wash stage—especially if you use a towel like the Orange Wash Microfiber Towel.
Common Mixing Mistakes to Avoid
- Adding too much soap thinking it’ll “foam better”
- Using hard water—it kills foam (use filtered if possible)
- Not shaking the bottle before foaming
