“Borax softens hard water, removes residue, and boosts the quality of detergent,“ says Cobb. “It’s all-natural and safe to use, and it works great on whitening whites.” Follow the directions of the box.
Another household item to try: white vinegar, which acts much like lemon juice. Cobb suggests adding 1/4 to 1/2 a cup of white vinegar to a load of laundry, then launder as usual. One household item Cobb says to steer clear of: ammonia. “It’s very alkaline, too hard on fabrics, and if you use with bleach it can be hazardous to your health.”
