The Extreme Snow Foam Lance is an essential tool for any car care enthusiast. Constructed from a quality solid brass body, the Extreme Snow Foam Lance can be used with any snow foam on the market. It fits directly onto a Karcher / Bosch / Kew / Alto / Lavor pressure washer like any other attachment with the separately supplied adaptors. The nozzle on the snow foam lance can be adjusted to deliver varying patterns of foam. The valve on the top of the lance regulates the dilution rate so you can alter the snow foam concentration. We recommend using Linntec Extreme Snow Foam, although this lance can be used with any suitable shampoo or Snow Foam formula. Used with Snow Foam, it is possible to produce a very thick layer of foam which clings to the surface of the vehicle to remove dirt, grit, grime and mud away from all surfaces. By encapsulating and removing much of the dirt and grit prior to shampooing, there is much less chance of creating swirl marks and scratches with your wash mitt.
