A method of cleaning a fluid handling device, comprising:
- inserting a tip of the fluid handling device into an interior of a channel through a first opening disposed at a first end of the channel;
- causing a plasma to be formed within the interior of the channel;
- and
- removing the fluid handling device from the channel through the first opening, wherein the step of causing a plasma to be formed further comprises aspirating reactive and energetic components of the plasma into the fluid handling device.
