There are many natural cleaners on the market these days, some of which still have synthetic fragrances that end up in our water supply. Fortunately, you can make great, environmentally safe cleaners out of household items. The acid in white vinegar makes it naturally capable of killing mold and bacteria; you can use it to clean mirrors and windows. Baking soda is also great for deodorizing. Lemon juice is another bacteria battler and sodium borate, aka borax, is a multi-purpose cleaner that's useful for scrubbing walls and floors.
