DIY hand soap

This hip trick is along the same lines of the dish soap diluting trick on page 7 in the book. Stop spending money on hand soaps! Buy a refillable pump (there are even cute ones to be found out there, too) and fill it halfway or even a quarter of the way full with the Castile soap of your choice. Top it off with water, give it a shake and feel good about not putting extra chemicals down the drain, for cutting out unnecessary packaging and keeping toxic perfumes out of your home.
