foam gun/ canon how do you foam

Foaming and going straight to washing doesnt make sense to me.

Foam, rinse, wash.

Is your foam cannon adjustable?

 

Yes, it is on the max setting and I do have a water softener. I'm going to try another ounce of maxi suds and give it a good shaking.

 

Would you get even more "shaving cream" foam by just hooking up the bottle of soap to the cannon? Instead of mixing soap and water.

 

Not very cost effective though.
