Many car washes nowadays have started using snow foam before the actual washing process because it makes washing easier. Snow Foam is a unique kind of detergent that is used as a pre-wash agent to loosen up the dirt that is on your vehicle. A thick layer of the snow foam is sprayed and left on the car so that it can lift the dirt off the car.
But it is not as simple as washing your car which, can be done with a sponge and a bucket of detergent water. If you are planning to do it by yourself, you will need a snow foam lance, a lance bottle, a pressure washer, and the snow foam liquid. Most Snow Foam Car Wash services nowadays have all the necessary equipment, and it is cheaper to let them wash your car.
