Snow foam = bubble bath for the car that seems to have gained some popularity UK - marketing at its worst.

After hosing off the obvious clumps I find a hosepipe in one hand and a soft sponge in the other - rinsing sponge every wipe and keeping water flowing over the area of interest is just as effective and undamaging and quicker than setting up pressure washers and foam lances i have my own borehole so water use not an issue - or since I live in Wales I can just wait a few hours and rinse it during that days rainstorm
