I guess I'm a bit more low-tech than most of you guys. I pump sanitizer through mine, making sure to pull out the interior piece to its max extension to fill the whole chamber with fluid. Then I spray the outside with Star-San. After use, I pump about a quart of cold water through it, followed by another flush with sanitizer. No problems ever. I hang it to dry with the hose at full extension so all the drips can drop out.
