I can relate to this---I've purchased (yet another) used 10 gallon tank that I'm going to have to clean. If there's a lot of dust on it, I'd stick it in the shower and give it a good rinse so I can see if there's any crud on it. If there is, I'd fill it with warm water and let it soak to see if any of the crud softens; you can use white vinegar to help clean it, as Jenaero said and rinse repeatedly.
If, for some reason, you think it should be disinfected, skip the vinegar and use a diluted solution of bleach and water to go over it. I use 2 oz. of bleach to a gallon of water. Rinse very, very well with running water. I usually wind up filling the tank with water even after I've rinsed just for good measure. If you can, let the tank air dry for a day or at least overnight.
