This Tiny Laundry Tweak Helps Keep Towels Mildew-Free
Caroline Mullen explains a simple, cost-effective fix for persistent mildewy towels: adding a scoop of [[borax]] to a hot wash. She describes [[borax]] (sodium borate) as a laundry booster that stabilizes enzymes in detergents to brighten and deodorize fabrics, and notes safety concerns and EU restrictions. Wirecutter writer Andrea Barnes explains why borax boosts cleaning power and why some detergents — notably [[Tide Free & Gentle]] and enzyme-containing formulas like [[Tide Ultra Oxi]] — can eliminate odors even in cold water. Mullen contrasts that efficacy with her scented favorite, [[Mrs. Meyer's]], which may leave residues that trap bacteria, and recommends using either borax-plus-hot-water or a high-performing detergent depending on scent sensitivity, fabric care, and water hardness. She also mentions laundry stripping, potential dye loss in dark fabrics, and offers pragmatic advice for rotating methods to suit preferences.
