One way I save money is by picking up inexpensive bottles of soap with a coupon and “extending” the life of them. The main way I do this is by making foaming soap.
Frugal Soap Tip #1: Make your own foaming soap.
However, a few weeks ago, our foaming soap dispenser broke, and I needed another idea because the girls were using a ton of soap from the pump (I think they used up half of it in two days, and I can normally make one bottle of soap last for at least a month — if not more when we make foaming soap)!
Frugal Soap Tip #2: Use a rubber band to slow the flow of the soap!
When I was teaching, one thing I did was wrap a rubber band around the top of the soap dispenser — kids can go through a bottle of soap in a hurry! This makes less soap come out with each pump (but still plenty for washing hands, of course). It doesn’t look pretty at all, but it worked great in a pinch.
