Borax

Borax, or sodium borate, is an alkaline mineral salt. It disinfects, whitens and fights mold and mildew. It also kills ants.

Add half a cup of borax to each wash load, and you'll boost the cleaning power of your laundry detergent. Add it to your dishwasher for cleaner dishes; use it to clean your toilets, and beyond.

Though borax is natural, it is toxic. Keep borax out of reach from children and pets.
