We wash our hands a lot in this house. I mean A LOT. We also happen to love nice smelling, natural liquid hand soap. Such products are not budget friendly for a family with minor OCD. So, I came up with a solution that sends less cash down the drain, but doesn't sacrifice the nice-smelling-natural bit. Here's how: We invested in a few Method foaming hand wash pumps and a big bottle of Dr. Bronner's Soap (the almond is my favorite).
When the Method pumps are empty we fill them with about an inch of Dr. Bronner's and the rest of the way with warm water, mix, and voila! Saving some serious change, one sweet smelling pump at a time. As an added bonus, the foam makes it easier for independent little hands to get clean.
