Hmmm. This is a completely different kind of book/resource than I usually review. However, I live part-time in the tropics. If there's anything that's considered a wild idea, it's sustainable chemistry for cleaning.
Garbage is everywhere (except in bins), toxic chemicals are used on food crops, and "the harsher the better" seems to be the motto for locals who buy cleaning supplies.
This interests me for educational as well as practical purposes in a home and office where neither doors nor windows are sealed (handmade with large gaps). The winds blow smoke from garbage fires, dust, and pollution into spaces. The critters run in and out (lizards, roaches, ants, and more), leaving poop and tracks behind.
Thanks for this one. Going to put some of the ideas into my own bag of cleaning tricks - and see how much safer we can make the environment.
