Foam spray machines utilize a special formulation of soap and water to create a dense, thick foam. This foam clings to the vehicle's surface, providing an effective way to encapsulate dirt and grime. The residence time of the foam on the vehicle allows it to break down tougher contaminants, such as road tar, bird droppings, and tree sap. This process results in a more thorough cleaning compared to traditional water-based washes, which may merely rinse off dirt without effectively removing it.
