Why Choosing the Right Foam Cannon Soap Matters

Using the wrong soap can lead to runny foam, ineffective cleaning, or even paint damage. The right formula ensures:

  • Safe for all finishes, including ceramic coatings and waxes.
  • Highly concentrated — only 2–4 ounces needed per wash.
  • Works equally well in a foam cannon or traditional bucket wash.

How to Use Foam Cannon Soap

  1. Fill the Foam Cannon: Add 2–4 ounces of soap and top with water.
  2. Pre-Rinse: Spray the car with water to remove loose debris.
  3. Foam the Vehicle: Cover the car evenly and let the foam dwell for 3–5 minutes.
  4. Rinse & Wash: Rinse off foam, then wash with a high-quality wash mitt.

Why Use a Foam Cannon?

Foam cannons provide a safer wash by pre-soaking your vehicle, softening dirt before you touch the paint. This greatly reduces the risk of swirls, making it essential for maintaining a flawless finish.
