I really like this link: http://www.ecologycenter.org/factsheets/cleaning.html. Since I’m not fond of cleaning with chemicals, this offers many natural “recipes” — like using baking soda, vinegar, and hot water to unclog a drain, which I just did this evening. Fun when you can do what needs to be done in relatively safe ways and that aren’t expensive. And fun to watch the vinegar and soda fizzle like a volcano. ; ) So many uses for these products, and for lemons and limes and other household items, like toothpaste.
