If you choose only one room in the house to invest in green cleaners, choose the bathroom. Many conventional cleaning products contain chemical artificial fragrances and ammonia, which can be irritating to the skin, eyes and lungs. Since bathrooms are some of the smallest rooms in the house and get the least amount of ventilation, cleaning with toxic supplies can lead to an unhealthy environment. But before you buy green cleaning products at the store, consider making your own to save money. You can find a whole host of natural solutions online that use nontoxic ingredients like white vinegar, baking soda and rubbing alcohol.
