After this deep-cleaning ritual, run a final empty cycle with just water—no vinegar, no baking soda, no anything. Check your glasses: if they sparkle like a wedding cake, you’ve beaten the hard water. If not, repeat the process once more, because sometimes limestone takes two rounds to surrender.
And if all else fails, accept that your dishwasher is a high-maintenance drama queen. Hard water is a natural disaster in appliance form, but with a little vinegar, a pinch of baking soda, and a lot of cursing under your breath, you can reclaim your sparkle. Now go pour yourself a glass of water—but maybe use a filter this time.
