Mine was ever so slightly better than 'very soapy water'. I was pretty happy with it.
But for £8 of the Queen's finest instead of having to buy a pressure washer and lance gubbins etc, and the faff of a pressure washer, 'tis great.
Prefer this tho...
Once you can say "Also available in white" thats when you are using snowfoam right.
If you get only slightly better than soapy water, then there is no need for you to buy snowfoam at all.
It's a waste of your money and you'll get the same result if you just used car shampoo instead.
Just my opinion tho
