What is this vodka wash you speak of?
To avoid having fingerprints, etc. burn into the manifold, you rub it down with alcohol so it is perfectly clean. Just before you fire it up for the first time you rub vodka all over the manifold. As it burns off it'll turn the manifold into a pretty colour i.e. the nice gold colour mine came out in. Should probably point out that this will only work on a new manifold and you only get one shot at it (no pun intended).
