One of the tv investigative shows did a test with all brands of vodka. From the expensive to the cheap. The vodka drinkers said they could pick their brand from all the rest. No one could. They all picked the cheapest brand as the best and thought it was their brand. Vodka and water will not make starch but you can put a drop of essential oil of lavender in the mix and use it as steam in your iron. Smells wonderful.
