Black cotton clothes fading to gray? Those pricey "special black" restorers often disappoint. As someone who's tested countless laundry hacks over years of managing wardrobes, I discovered a surprising, effective solution: beer. I tried it myself, and the vibrant black returned—guaranteed to amaze.

1. Load your black cotton clothes into the washing machine.
2. Select your usual wash cycle.
3. During the rinse cycle, add one glass of beer.
Your black cotton clothes will regain their deep, original color! It's simple, highly effective, and incredibly economical.
And if you're into brewing, here's my beer recipe.
