for those that dont know what snow foam is:

"The foamster will cover your vehicle in a thick layer of foam encapsulating and softening the dirt and grime. Because the foam clings much better to vertical surfaces it can be left to dwell for longer without drying which really allows the emulsifiers and surfactants to work much better than traditional wash methods. This means that when it is rinsed off much more of the potentially paint damaging dirt is removed. A further layer of foam can then be laid onto the vehicle and washed using a soft washmitt for the safest wash possible"
you can buy the proper foam lance

just attachs to the end of the hose pipe and basically u just fill the bottle with "snow foam" (a 5l bottle is about a tenner)
used in conjunction with a woolen mitt, its so much easier to wash the car!
