So you've watched Seventh Generation's new television commercial, and have decided to replace all the toxic chemical cleaning products under your sink with natural versions. Getting rid of the old stuff is pretty easy. All you need is a big box or bag and a means of transportation.
Collect any cleaner that doesn't disclose all its ingredients or has hazardous ingredients. Put the box inside your car or in a bicycle bag. Head to your nearest hazardous waste collection site and drop off your old cleaners. That's it in a nontoxic nutshell.
You can find your nearest hazardous waste site by entering your zip code at Earth911 or by typing your city, state, and the term "hazardous waste" into the search box of an internet browser.
Different cities will have different schedules. Here in Burlington, VT, we can go to a local depot four days a week. In Thousand Oaks, California, on the other hand, there's a monthly collection day you sign up for in advance. Whatever you do, just don't pour anything down the drain. The reasons you don't want toxins in your home are the same reasons you don't want them floating around in the environment!
