This helps your solution mix together. - Adjust the spray nozzle first to find the stream of water that works for you. You can adjust it so that it sprays in a decent fan pattern. - Adjust the knob on the top to control how much water is mixed in. The minus (-) sign indicates less water (so more foam is produced), and the (+) indicates more water (so less foam is produced). DO NOT max out the knob onto the (-) side otherwise you wont get much foam. You can turn it all the way to the (-) then dial it back a little, this produced a ton of foam.
