Hello Gents. I bought a snow foam lance from polished bliss a few weeks back. When I turn the adjuster towards the + it dilutes the mixture, and when I turn it towards - it thickens it up giving more foam. Is this right, as it dosn't seem right??? You would think that turning it to the + would give you more foam, not the opposite! Daft Q I know, but it's annoying me!lol! Any ideas? Lastly, I am running it through a Karcher K Series (one of the 100bar models). I have tried all sorts of mixture ratios, and am filling with hot water as described on the PB website. I use Megs hyper wash. The foam its producing is ok, but its not as thick as I'de hoped. Its not sticking to the car for very long. Nothing like I've seen in some pics of really thick, dense foam. I've tried all the settings, and usually use 200ml of hyper wash and fill the rest up with warm water and shake. I have also tried using more to get thicker foam but to no avail! Where the hell am I going wrong, or do you guys think I have a faulty lance? Any help would be fantastic. Cheers Fellas, Ollie.
