Some foods are preserved in vinegar. This is the case with pickles, for example.
Why not reuse this vinegar once the jar is finished?
Luckily, there's a trick to not wasting the vinegar instead of throwing it away.
The trick is to use it to clean your sink. Watch:
1. Open a can.
2. Separate the vinegar from the food.
3. Collect the vinegar.
4. Use it to clean your sink for example.
And There you go ! You reused the vinegar from your pickle jar :-)
Other vegetables are preserved in vinegar such as certain olives or sweet and sour vegetables. Don't forget to recycle it too.
You can then clean a sink, or throw it in your toilet to descale it. And even if this vinegar has a little pickle smell, it doesn't matter, its effectiveness is still present.
