Go here to see an easy way to make your own foamy soap. Thanks Money Saving Madness! This is a great money saver! I tried this today and used the Dawn Hand Renewal Dish Soap that I bought at K-Mart several months ago during the double coupon days. I think I paid less than $.75 for a 22 FL oz. bottle. Another idea is to use the hand soap that is left in the bottom of the container that won't come out of the pump. I never know what to do with that. I don't want to waste it and throw it out but I also don't want to try to pour it out when I need to wash my hands. Leave a comment if you have another great tip or idea for making foamy soap!
