Chemical-based cleaners can be harsh on both you and your wallet. Jennifer Roberts, author of Good Green Kitchens: The Ultimate Resource for Creating a Beautiful, Healthy, Eco-Friendly Kitchen (Gibbs Smith), suggests raiding your pantry for alternatives. Baking soda sprinkled on a damp sponge is terrific for scouring; distilled white vinegar diluted with water (use equal parts of each) will make windows and mirrors sparkle. Inexpensive liquid Castile soap, found at most grocery stores, is a great all-purpose cleaner for sinks, counters and other surfaces. These nontoxic, environmentally friendly substitutes take care of messes for a whole lot less.
