hard water grout cleaning 18

Dealing with hard water stains on grout is a real chore—those white, crusty mineral deposits seem to cling to every line between tiles. I’ve found that a simple paste of baking soda and white vinegar, scrubbed gently with an old toothbrush, lifts most of it without damaging the grout. Rinsing thoroughly afterward leaves the bathroom looking much fresher, though you might need a commercial cleaner for stubborn buildup.
