Some tips for using the foam gun correctly :
- Fill the bottle with hot/warm water before adding soap. 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.
