1, it is recommended that the ratio of aged vinegar to warm water be controlled at about 1:10.

2, no matter using aged vinegar to soak feet or using white vinegar to soak feet, the bactericidal effect it plays is mainly the acetic acid component in it, and the proportion of acetic acid component in aged vinegar is less. So when you soak your feet, if you add less aged vinegar, the acetic acid will be diluted, then the bactericidal effect is very small, and the added aged vinegar should be more. The ratio of vinegar to warm water is controlled at about 1:10, which can make the vinegar work and avoid the skin being stimulated by acetic acid, which may cause discomfort.
