I read on a post a couple of years ago that applying Vodka or pure vanilla will sanitize a surface to make it food safe.
For example. A lot of cakers use foam core board as a cake base or cake circles, instead of the normal cake circles you get at your local bakery store.
Well, foam core is not food safe. Someone recommended to use Vodka to sanitize it and when the alcohol evaporates, the surface is now food safe and there is no need to apply a clear food safe wrap over it. Apply cake directly on the foam core would be fine....
