Most Lances will have a directional nozzle and a snow foam liquid flow rate adjuster.
 

Take your time to set the lance up and you will achieve the best possible results producing a rich thick snow foam pre-wash. Our tests have shown that the normal flow rate of water through your pressure washer using the vertical direction on the nozzle combined with the liquid flow rate adjuster turned to maximum will produce the best possible results. The amount of rich thick foam will also depend on your mix, for best results it is recommended to use a 50/50 ratio but again it is really your choice.

We have tested our Pro-Kleen Snow Foam with most makes of pressure washers resulting in fantastic results across the board, so whatever your make of pressure washer once it is set up correctly you wont be disappointed.
