Homes that have hard water are usually victim to showerheads and sink faucets that have white, caked-on mineral deposits that make for ineffective or sporadic water flow when using them. Instead of replacing them with new fixtures, try this inexpensive and eco-friendly way to clean them instead. Fill a freezer bag halfway with white vinegar, and immerse the fixture in the bag; use a rubber band to secure it in place, and leave it alone for at least two hours. The white vinegar will naturally break up the mineral deposits and leave it sparkling clean.

Another reason to treat your lawn using organic and non-toxic treatments: Your grass clippings could pollute your water. When grass clippings from chemically treated lawns end up washing down storm drains, the contaminated clippings can bring chemicals into public water supplies. Trace amounts from your household (multiplied by the hundreds if not thousands of other households) can send a significant amount of chemicals down the storm drains. To prevent this, go organic and chemical-free, leave the clippings on the lawn or compost them far away from storm drains.

Insulation in the attic of the home is one of the most economic and effective ways to keep a home both warm in the winter and cooler in the hot summer months. But having the insulation improperly installed can actually cause problems. Over time, insulation can shift and move around, so be sure the "vapor barrier" on the insulation is facedown, and not faceup. If it's faceup, the insulation can actually trap moisture and become a breeding ground for mold. If flipping the insulation isn't easy, you can take a box cutter and cut small slits randomly on the insulation to allow trapped moisture to escape.
