Household cleaning products may contain harmful chemicals that are toxic to humans, animals, plants, and the environment. A green household should have these natural products on hand — baking soda, borax, distilled white vinegar, hydrogen peroxide, lemon juice, olive oil, vegetable-based liquid castille soap, and washing soda. Howdini.com demonstrates some uses of these ingredients and suggests natural substitutes for traditional cleaners. For those who don’t have the time or desire to become mixologists, environmentally friendly products are available for purchase.
