Foam Cannon Soap Ratios & Dilution Guide
If you want maximum foam without wasting product, getting the dilution right in your foam cannon is essential. Too much soap can leave residue, while too little won’t provide enough lubrication to protect your paint.
Why Soap Ratios Matter
The correct soap-to-water ratio ensures that you’re cleaning effectively without damaging protective layers like wax or ceramic coatings. Overly strong mixtures can strip protection, while weak mixtures won’t provide the foam thickness needed to safely lift dirt.
Recommended Foam Cannon Ratios
For most foam cannons, I recommend the following starting points:
- Ceramic Coated Vehicles: 2–3 ounces of The Super Soaper topped with water.
- Waxed or Sealed Vehicles: 3–4 ounces of The Super Soaper topped with water.
- Heavy Cleaning (road salt, mud, bugs): 4–5 ounces of The Super Soaper topped with water.
How to Mix Your Foam Cannon
- Fill your foam cannon bottle with water first to avoid excessive foaming during mixing.
- Add the desired amount of soap based on your vehicle’s needs.
- Gently swirl to mix — don’t shake vigorously.
- Apply foam evenly from top to bottom and allow 3–5 minutes of dwell time.
Pro Tip
If you live in an area with hard water, slightly increase your soap ratio for thicker foam, or use filtered water in your foam cannon bottle.
