Thanks for the swift response everyone. While I know the drip tip is the only thing that will come into direct contact with my mouth, I just am a bit "chemical-a-phobic" when it comes to using a tank from someone I don't know. Who knows what kind of junk people are trying to vape in their tanks?

The O-rings is a good heads up, I probably would have overlooked that, and I doubt I will be getting any extras from a used tank buy. I don't want to deal with alcohol, but rubbing alcohol might be a good second option. As for the ultra sonic cleaner, I really need to get me one of those, especially considering how much my DIY hobby has stepped up... my birthday is coming up in june
