Applying vinegar to rust dissolves the oxide and leaves behind a water-soluble salt that you can remove easily. It is called neutralisation, and this reaction happens between rust and acetic acid, which is why cleaning vinegar helps remove iron oxides from household surfaces and objects.
Allow the object to soak in the vinegar for at least 30 minutes. Check the progress. Excessive amounts of rust will require longer soaking, up to two hours.

Leaving a baking soda and vinegar mixture on stainless steel for about 5-10 minutes is usually enough. This allows the mixture to work on stains without causing damage to the surface.

Almost Indefinite Shelf Life
Vinegar is a fermented product and has an “almost indefinite” shelf life according to the Vinegar Institute. “Because of its acid nature, vinegar is self-preserving and does not need refrigeration. White distilled vinegar will remain virtually unchanged over an extended period of time.
Both distilled and white can be used in cooking, cleaning, food preservation, and for medical and laboratory purposes. However, since white is stronger than its counterpart, it is more suitable for cleaning and disinfecting.
