Like many people I know, I keep a cabinet STOCKED full of my favorite brand and scents of anti bacteria foaming hand soaps. When my favorite store has their big 75% off sale, I go! Sadly though, I missed the last one! :( Suddenly I realized one of our bathroom soaps and our kitchen soap was almost gone and I had already used the last of my stock pile! BUMMER!! But then I remembered "I have the foam pumps!" All it take is about 2 table spoons of any liquid soap and water to create a FULL bottle of foaming soap! Just put the soap in the bottle, add the water and shake! It's that simple! You can use any liquid soap and it will work. Also, I know a lot of people are starting to make their own liquid soaps. It works with those too! So the next time you find yourself with empty foaming soap pumps, or you are looking to save a little money, remember this!! Happy soap making everyone!!
