Hi all, just thought i'd share my thoughts on the Karcher 'FJ6 Foaming nozzle', which i assume is the £20 lance referred to in this thread. I know this is an old thread but i don't think my review necessarily deserves its own post; and this thread is the first result on a search for 'snow foam lance'.
I'm a complete detailing novice so these products are all new to me. This is the first snow foam lance I've used (at home) and i don't really have any point of comparison, other than the self use car wash places.
After some deliberation i decided to give this lance a go; there are LOADS of good and bad reviews online so the only real decider for me was the price - £18 delivered to my door. This is better than half the price of a pro lance such as the autobrite etc..
In a nutshell, you get what you pay for. I used the FJ6 with quartz snow foam, a product highly praised by forum members who clearly know a thing or two about detailing.
Quartz recommend using 1 part solution to 10 parts water for a thick foam.
I used 1 in 6 - the FJ6 has a 0.6 litre bottle.
My car was very grubby after nearly a month of motorway driving and bad weather. I didn't pre-rinse the car, thinking the foam would cling to the muck and penetrate better.
Below are some pictures of the results, which I think speak for themselves. (hope these images aren't too big??)
pre-wash//immediately after foaming//post wash.
I allowed the foam to sit for a good few minutes, but as you can see it wasnt even remotely thick and didnt hang around for long. This was using the lance on the MAX setting, which only worked if you held the trigger and then slowly turned the knob. If you look at the last image you will see the solution just pours out like a hose if you try to use it on the max setting.
I then jet washed, and allowed to dry to properly see the results...
