Hi -- I'm not sure which board to put this on, but since toxins affect your health, I guess this will be okay. I dislike cleaning chemicals -- they tend to give me headaches and other unpleasant symptoms, and besides, I don't think they're very good for people or for the environment. (Well, duh.) My mom sometimes uses baking soda to clean things like stained coffee mugs, and I've seen how well it works; I've heard that diluted vinegar is also an effective cleanser; so I was wondering whether you can use things like that to clean, say, a bathtub or toilet.
