これさえ読めば安心! How to Get Rid of Tea Stainsの進め方をロジカルに解説します。

White vinegar is the stinky cousin of cleaning products. But it’s worth the temporary nose assault.

Mix equal parts vinegar and warm water directly in the stained mug. Let it soak for about 15 minutes. Go check your phone, pet your cat, whatever.

When you come back, dump the liquid and rinse. The stain should slide right off. If it doesn’t? Add a teaspoon of salt and scrub lightly.

Your mug will smell like a pickle factory for a few seconds. Trust me, the rinse cycle fixes that. Your tea will taste like tea again, promise.
