Here's the secret of foaming hand soap: it's all in the pump. That's right! You can use whatever liquid soap you want, as long as you have a foaming pump container. I found two bottles of Bath & Body Works soap at a garage sale last year, both of which have foaming pumps. Or, you could go to Walmart and buy a new bottle for a couple dollars.
How to Do It
To make foaming soap, fill the container with water up to an inch from the top. That's right- I said water! Then add a tablespoon or so of liquid soap. You can use the fancy-pants liquid castile soap, but I just used plain old dish soap because we really like the scent. Hubs likes it because it cuts grease better than regular hand soap. Some people also add a little bit of oil to the soap, in order to preserve the life of the pump.
Then, swish the water/soap mixture around a little bit to blend, and screw on the top. Squirt out a little bit of soap to see if it worked. Voila! Using foaming hand soap is super frugal. Not only does it cost mere pennies per bottle, but there is less waste than with bar soap. Plus, it takes less time to make than it does to find a bottle at the grocery store.
Happy foaming!
