Ok, I'm gonna get all scientific on ya here - it won't work as good as the alcohol.

the dessicant will only pick up the water as it evaporates - the alky displaces it immediately. the goal
being to get rid of the water before in the process of evaporating it corrodes the contacts. The alcohol
displaces the water and dries without leaving corrosion

dessicant after the fact won't hurt. but won't do you as good as methyl hydrate will.
