· Does it work without a pressure washer? Yes, our Foam Gum is designed to connect directly to any garden hose with standard U.S. hose threads - no pressure washer or water bucket needed!

· How much foam does it produce compared to a pressure washer? It produces good thick cleaning foam for a regular car wash at the convenience of your home.However, the water pressure from the garden hose (~60 PSI) is not as powerful as from a pressure washer (>1,500 PSI).

· What kind of soap should I use? Use a car wash soap that is labeled for "foam cannon" or "high sudsing."Or use our Power Foam soap ss that we specifically formulated to produce thick dirt-fighting suds.

· How do I adjust the foam output? Simply adjust the soap-to-water ratio dial with the number "0" for maximum foam output, or number "5" with more diluted foam to cover larger surface areas.

· Will it wash my entire car? One full container of soap & water mix is typically enough to wash a regular size car. For larger SUVs, trucks or vans, or heavily soiled vehicles, you may need to refill to remove all dirt.
