Not used this one Roger - but it looks pretty expensive. A few of us use www.cleanyourcar.co.uk who do a whole range of snow foams. I'm using their Super Snow Foam at the moment and finding it frighteningly effective at producing a thick blanket of foam that seems to shift just about everything. Charlie's idea for a warm water feed to the pressure washer works brilliantly with snow foam as well as avoiding frost bite on the operative and ice formation on the car.
