A few months back I bought a pressure washer to use at home cleaning the cars etc. I've always used normal car shampoo whenever I've cleaned cars in the past, my favourite one being Turtle Wax. On some detailing websites I've seen people using snow foam with bottles that have adjustable valves on them. I'm curious as to how effective snow foam really is, and whether it's worth the extra expense to buy it along with the better shampoo bottle? Do you literally just spray a slightly thick layer of snow foam on and then leave it for a bit? Or is some scrubbing involved like with conventional shampoo? I'm quite interested in using snow foam as it could mean I don't have to spend ages scrubbing the body panels with a sponge or micro-fibre cloth Please post up your experiences with snow foam, and the names of the products you've used. Thanks!
