Apparently someone here is misreading. Chinchillas was pointing out that it would be better to use a vegetable washing liquid to quickly clean our veggies and fruits rather than soaking for a long period of time in water because many of the vitamins in fruits and veggies are water soluble.

One of the natural ingredients used in these washing liquids is corn.... corn alcohol....
