This was probably the first homemade version of home cleaning products I made, and I was (and am!) thrilled with how little it costs to do. The trick to make it foam is in the dispenser. It has a dual pump. One for air, and one for soap. When it comes out, it is foam. A regular dispenser will not work. It has to have the dual pump. I just think this is so neat, and CHEAP!
So here’s how you do it. Put ONE tablespoon of Dawn, or any dishwashing soap in the dispenser, then fill to ALMOST the top with water. That’s it! You can adjust it for more soap if you want, but this works for us.
Now go make some foaming hand soap. I know you want to!
