After seeing some videos online about how good snow foam can be, I went ahead and bought the official Karcher Snow Foam Lance to go with my Karcher K2 Compact pressure washer. I used Demon Snow Foam, and Valet Pro ph Neutral Snow Foam with the Karcher foam lance. The Demon Snow Foam, in my opinion, is a waste of money, as it has a panel time of about 2 minutes, before it's all run off. (See my update below about Demon Snow Foam) I then tried the Valet Pro pH Neutral Snow Foam, and though this did have a longer panel time, the snow foam was not as thick as I'd seen in videos online. So, after the negative experiences above, I will admit I wasn't expecting much today when I went out to test my new Autobrite Snow Foam Lance. I'm happy to say I was pleasantly surprised, both with the lance itself, as well as the Valet Pro snow foam. Autobrite Snow Foam Lance - The pictures below show the Autobrite Snow Foam Lance. Looking at the long feeder tube, the filter on the end of the tube, the metal bottle cap, as well as the adjustable nozzle (more on this below) and mixture strength dial, this looks to be of a high quality build. And for those of us that take detailing just a little bit too seriously, this sticker is on the bottle... The foam lance comes with the Karcher K series compatible adaptor already connected, so it is ready to go with a Karcher K series pressure washer. If you have a different make washer, ensure you get the lance with the relevant adaptor attached. Valet Pro pH Neutral Snow Foam - The Valet Pro comes in a 1 litre bottle (5L bottle also available), with instructions of what mixture to use, depending on the washer type you are using (pressure washer or hand held applicator) For a pressure washer, it says to mix 300ml of soap with 700ml of water in the foam lancer bottle. Not much else to say about the Valet Pro itself, except to point out (as the name indicates) that it's pH Neutral, which not all snow foams are. Using them together - As the foam lance has a 1L bottle, I used the recommended mixture, and then set the mixture strength dial on the foam lance all the way 'down' (thickest foam). I say 'down' because you need to turn it in the direction of the '-' symbol. I then adjusted the nozzle on the foam lance to see the different types of sprays it produces. The three spray types for the nozzle are - Horizontal spray Single jet Vertical spray (this looks like it isn't foaming as I had run out of mixture when I took this picture - sorry) I'm not sure what you would use each of the spray types for, but I found that the single jet of foam seemed to produce a slightly thicker foam. The horizontal spray seemed to produce a 'scattered' horizontal spray pattern, while the vertical spray produced a vertical, much narrower 'targeted' spray pattern. For my car, I mostly used the vertical spray pattern, moving slowly across the car. This worked a treat, and the foam that came out was thick and stuck to the car as I'd seen in demo videos online. The panel time of the foam was easily more than 5 minutes, as I started washing it off after the recommended 5 minutes, and there was still a LOT of the foam on the car. After foaming the whole car (with the vertical spray pattern), I took some pictures, and you can see the foam is sticking to the car nicely After 5 minutes, I used the Karcher to rinse the car thoroughly, and then gave it a hand dry (thick towel to get most of the water off, followed by a microfibre cloth to dry and buff). Below are the results - Note that this is purely a snow foam and rinse - no washing with soap after the snow foam. What really impressed me was how clean the wheels were, without me having to scrub them. I'm really happy with the results of the foam lance as well as the snow foam. After snow foaming my car more than I would for a normal wash, as I was trying different spray patterns, so made more than one pass over the car, I used up the full 1 litre of mixture I had made. I expect from the 1L of Valet Pro, I could probably get 4 washes of my car, however in future I will probably change the mix strength down a little, and get it to last a bit longer, but I guess it's a little bit of trial and error to get the mixture and lance spray settings just right.
