A leaky toilet can waste around 200 gallons of water per day. If you have a leaky toilet, make the effort to get it fixed. Also, take notice when you see water-wasting toilets at work, in hotel rooms and at the gym. These are easy places to report broken fixtures to management so they can be fixed. Not only do these simple steps save water, they also help reduce greenhouse gas emissions, since it takes energy to pump and treat water, too.

Those fizzing tablets used to get dentures sparkling clean have myriad uses around the house. If you have reusable plastic storage containers that have been stained or have an odor from, say, leftover eggplant Parmesan, fill the container with warm water and two tablets. Wait an hour, and rinse to reveal a like-new container. This also works wonders on coffee-stained mugs and cups. And if you love your slow cooker, use tablets to get the inside sparkling clean.

Many of us are looking for all-natural or eco-friendly cleaning products to use at home. The good news is that there are many great brands to help you get your home sparkling clean. But since cleaning products are not required by law to list ingredients, it can be hard to tell if something is nontoxic or not. Since all cleaning products need to have a warning in case of accidental ingestion, see what level of toxicity is marked on the product. A product labeled with the word "caution" is less toxic than products labeled with the words "warning," "danger" or "poison."
