Our garden hose Foam Gun produces a clinging foam that produces a scratch-free car wash to give your car an excellent wash with less work. The Foam Gun works with any standard garden hose. No pressure washer is required. The Ceramic Garage Foam Gun makes washing your car faster, easier, and more fun. The advantage of washing your car with a foam cannon is that it gently removes abrasive dirt particles without grinding them into the paintwork. The foam gun combines a soapy water solution such as using Ceramic Garage Snow Suds with air and running water from your garden hose to spray foam. Turn the dial on your foam gun to adjust the dilution ratio of the soapy foam sprayed from the nozzle. The adjustable nozzle makes setting up a home touchless car wash easy.
