We’re testing the snow foam lances here, rather than the snow foam itself, so we used the same household brand solution in every foam gun, diluted as recommended according to the manufacturer, and with the guns’ adjustable mixture setting at maximum.
All were applied to a filthy but dry car using a mid-range Karcher pressure washer, and then left for 10 minutes before rinsing off. Our snow foam lances ranged in price from budget options to pricier equipment claimed to be preferred by expert detailers, and we rated the effectiveness of the foam coverage as well as the quality of the lance and bottle, and how easy it is to fit the gun to the pressure washer.

Autoglym Polar Blaster
Fits: Karcher, Kew, Alto, Nilfisk, Nilfisk Pro, Kranzle and Lavor
The Autoglym bottle and nozzle feels reassuringly heavy duty, with brass fixings and a spring-loaded adaptor for the Karcher K Series pressure washers - though it also fits a wide variety of other pressure washers. The spring-release adaptor for the Karcher makes the Autoglym assembly a doddle to fit, and it’s also easy to fill thanks to the bottle’s wide neck and clear measurement lines. When attached, the snow foam gun rotates on that adaptor joint so that it stays level, which is a neat trick.

Great though the myriad of car cleaning stuff there is now, the problem is are they owners who don't clear the mess away after there done.
