All. Now don't get me wrong, welders prep their work (mainly non-ferrious) with isopropyl alcohol. But the heat in turn burns away majority of the oxidation. Just using alcohol is asking for trouble with ferrious metals; i.e. steel, stainless, iron.
Also using beer and other such beverages is a bad idea, because of it's pH balances leans more towards highly acidic. Hence why using the lemon juice and baking soda is better, baking soda is a natural pH balancer.
Cleaning your hookah is always one thing, but understanding the metal is another. Know how the metal reacts to certain agents and it will last longer the most.
