Foam Cannon Soap Ratio Guide – Don’t Waste Product!

Too much soap = wasted money. Too little = zero foam. Here’s the exact foam cannon dilution ratios pros actually use to get thick foam, better cleaning, and zero swirl marks.

🔬 Why Foam Ratio Matters

If your foam cannon isn't performing, the first thing to check is your dilution ratio. Using the wrong amount of soap can result in:

• Runny, ineffective foam
• Wasted product (and money)
• Increased risk of scratching from improper lubrication

✅ Best Foam Cannon Soap Ratio (Standard Setup)

For most electric pressure washers and standard foam cannons, use this ratio:

• 4 oz of soap to 28 oz of water in your foam cannon bottle
• This gives you a 1:8 soap-to-water ratio inside the bottle

Then, depending on your pressure washer's flow rate, that solution gets diluted even further as it sprays out. That’s where high-performance soaps make a difference.

🧼 Use a Soap Designed to Foam

Not all soaps are engineered for foam cannons. Some dilute too thin and won’t cling. That’s why pros use something like:

The Super Soaper – optimized for maximum foam, cling time, and safe cleaning.

🧪 Adjusting for Water Type & Foam Preferences

• Hard water? Bump up to 5 oz of soap to help counteract minerals.
• Using a foam cannon with a gas pressure washer? Try 3 oz—gas units often foam more efficiently.
• Foam freak? You can safely go up to 6 oz per 28 oz of water for max suds.

🧰 Pro Setup for Thick Foam Every Time

• Foam Cannon: MJJC or similar high-foaming unit
• Soap: The Super Soaper
• Water: Filtered or softened for fewer spots
• Pressure Washer: 1.4 GPM minimum / 1,800 PSI+ for optimal foam
