Pliny was wrong about lots of things and this is another one. Vinegar is a fabric SOFTENER - the complete opposite of a fabric stiffener. Mixing vinegar with salt produces hydrochloric acid and sodium acetate. Hydrochloric acid degrades the fibres in textiles, which weakens the material, so it would be pretty silly to apply it to cloth armour.
