I'll give you a few first. I have many ways here, but I don't have much time. I'll send you a few when I have time:

The wonderful use of vinegar:

1. The towel is hard and tasty. Soak it in vinegar and alkali+water, and it will be as soft as ever.

2. clothes dipped in fruit juice and rubbed with vinegar can fade.

3. Stop hiccups: drink one spoonful of sugar and two spoonfuls of vinegar, and stop hiccups.

4. bitten by mosquitoes, there is no cooling oil, touch vinegar to relieve itching and swelling.
