Is your glass bottle looking dull from stubborn limescale buildup? Regular washing often falls short, especially when deposits form inside narrow necks where sponges can't reach.
Luckily, this tried-and-true grandma's method cleans the interior effortlessly. Simply add white vinegar and a handful of rice. Here's how:

- 1 handful of raw rice
- 1 glass of white vinegar
1. Pour the rice into the bottle.
2. Add the white vinegar.
3. Seal the bottle.
4. Shake vigorously.

And just like that, the limescale is gone! Your glass bottle shines like new.
Quick, simple, and highly effective. If the bottle won't seal, cover the opening with your palm or plastic wrap.
No rice? Coarse salt works just as well.
This method is perfect for carafes, decanters, crystal pitchers, or glass jars too.
White vinegar's acidity dissolves limescale, restoring the glass's inner shine and eliminating odors.
The rice acts as a gentle abrasive, scrubbing away grime and opacity.
For heavy buildup, warm the vinegar slightly before adding it for even better results.
