Answer:
Vinegar reacts with aluminum, too. Aluminum won't rust like iron, but vinegar will give it spots and blotches.
Vinegar was used as one of the main household cleaning and odor removal agents for a good reason. I think in general you can get numerous iron (III) and chromium (III) (which are less pleasant) salts and complexes aside from acetate, e.g. chloride/iodide if you use iodised salt or hypochlorite from chlorinated water.
Diluted acetic acid (vinegar) etches majority of steels quicker than the glacial one, dissolving its passivating Cr2O3 layer. Aside from concentration, reactivity also greatly depends on the steel type and acetic acid purity
