Here's how it works:
Contents - 1/2 potato

1. Cut a potato in half.
2. Rub the moist cut side over the dirty mirror.
3. Spray white vinegar on top.
4. Wipe clean with a microfiber cloth.

Voila! Your mirror gleams perfectly, reflecting a clear, precise image without a single streak. This method works wonders on old or tarnished mirrors too—quick, easy, and effective.
Potato starch breaks down stubborn stains and grime. White vinegar cuts grease and adds shine without scrubbing. The microfiber cloth absorbs residual moisture for a flawless finish.
