Tackling hard water stains in grout is a pain, but a mix of baking soda and vinegar can help break down the mineral buildup. Let it fizz and sit for a while before scrubbing with a stiff brush, then rinse well. For tougher spots, a paste of hydrogen peroxide and baking soda works wonders. It takes some elbow grease, but seeing that grout brighten up makes it worth the effort.
