1. Makes crystal glasses shine

Crystal glasses dull over time from infrequent use. Restore their sparkle by dipping them in cooled potato cooking water, then buffing with a soft, clean cloth. This also revives silverware (soak for 10 minutes) and mirrors.

2. Removes mud stains from fabric

For mud-stained clothes, soak the fabric in potato cooking water and gently rub. Stains vanish like magic—chemical-free. It works wonders on tarnished sheer curtains too.

3. Makes the tiles shine

Rinse tiles monthly with potato cooking water for a like-new gleam. Use sparingly to prevent dullness or stickiness.
