Written by Cassie Reese, this 44-page guide walks through making your own laundry detergent and household cleaners at home, arguing that the average household's eight loads of laundry a week adds up fast when you're buying store-bought detergent every time. The core case: homemade versions cost pennies per load, skip the synthetic chemicals that react with air to form byproducts like formaldehyde, and are safer to have around kids.

A practical starting point for anyone curious about DIY cleaning recipes rather than a deep dive into chemistry — more about giving you usable recipes than convincing you of anything you don't already suspect about store-bought cleaners.
