Done a bit of chemistry, how does an acid oxidise something? The acid provides hydrogen ions which in reality form H3O, water is H2O. So not sure how that works cause it is the hydrogen ions from the acid that do the work. Rust is an oxide. Vinegar is a weak acid which means not all the ethanoic (acetic) acid forms ions so you may be able to reuse it. To confirm, all you would have to do is measure the pH. This could be done using a swimming pool or soil test pH kit (universal indicator). Measure the store bought vinegar pH then the recycled stuff to see if it has enough umph to do the job again.
