Ordered myself a snowfoam lance and some foam solution to give this foaming thing a try. Ordered from cleanyourcar.co.uk - good price and delivery times.

Went for a bottle of their own brand foam and was a bit disconcerted to read on the bottle that it's classed as harmful and has limited evidence of it having a carcinogenic effect! Doesn't strike me as the best stuff to be aerosolising on a regular basis or releasing into the water course.

Are they all potentially toxic or is this stuff a bit dodgy?
